The principle of operation of a chemical dry closet
Such a toilet works by splitting waste with special chemicals. The splitting takes place in a sealed container - storage. Impurities enter the container, and a reagent is added there, which prevents the appearance of odor and breaks them down.
Of course, such a device can hardly be considered a dry closet, but still the use of the prefix "bio" depends on the substance that is added to it.

Chemicals for dry closet
- Formaldehyde-based products are an unsafe composition, so it is better to empty the tank away from housing and green spaces;
- Ammonium reagents - a few days after adding to the tank become safe;
- The solution, which includes live bacteria, is harmless, the contents after processing can be used as fertilizer.
Which peat dry closet is better to choose?
The vast majority of dry closets using peat are produced by Finnish companies, such as:
- Biolan;
- Kekkila;
- Piteco
The Finnish peat toilet for a summer residence is designed for the use of a filler that, in addition to peat itself, also contains sawdust. Advantageously, the Finnish dry closet and the size of the containers (110 liters) make them suitable for use by several people or the whole family.
Among domestic manufacturers, Piteco stands out clearly. Its peat toilets are inferior to the Finnish ones in terms of capacity, but they attract the buyer with the price and separation of waste into fractions and filters.
Peat composting dry closet
Peat dry closets can be conditionally divided into the following types:
- Composting dry closet - it needs electricity for waste separation, ventilation and drying;
- Capacitive, which are considered completely autonomous, since they really do not need water, electricity, or sewage.
Recently, a new Swedish-made composting dry closet Separett Villa 9011 is gaining more and more popularity, equipped with a system for drying waste mixed with peat and turning it into ready-made compost in the shortest possible time.
The company that produces this composting dry closet, in the description of the product, insists on its absolute safety for the environment due to the refusal to use any chemicals. Its benefits also include:
- 1. Economical consumption of electricity;
- 2. Absolute elimination of unpleasant odors;
- 3. No need to connect to the sewer, although the design still provides for this possibility;
- 4. The need to empty the tank at intervals of two to three months;
- 5. Thrift (no materials are spent, which will positively affect the family budget).
Features of the electric dry closet
This design is significantly different from the first two. The liquid from the electric toilet is discharged into a cesspool or sewer. Solid residues are sprinkled with disinfectant powder and dried or burned.
Waste in any case takes up a very small volume. After they can be applied as a fertilizer. Among self-contained toilets, this design is the most expensive and requires constant power supply and forced ventilation.
Without this, it will not be possible to avoid odors that appear when burning or drying solid residues. Therefore ventilation is a must.
#1: Cinderella electric dry closet
The plumbing fixture is made in Norway. It is considered non-waste. It does not need to be connected to water. The flushing process is carried out by means of a compressor connected to the mains.
For the normal functioning of an electric dry closet, neither biological nor chemical agents are needed. After the disposal procedure, the environmentally friendly mass at the exit
Waste incineration is carried out in a special container. After that, only 100% safe ash remains, from which the toilet is emptied twice a month. Such a dry closet works from a 220 V network. Ventilation is mounted through the roof or through the wall.
#2: Separett Villa 9011 electric dry closet
This electric dry closet is made in Sweden. Its distinctive feature is that it can even be connected to a car battery. The model operates without water connection. The liquid component of the waste leaves through a flexible hose, and the solid component in a 23-liter tank is dried and reduced in volume by up to 70%.
The body of the Separett Villa 9011 is made of impact-resistant material, so it is resistant to scuffs and scratches. The plumbing fixture is equipped with a comfortable polypropylene seat. Kit includes all parts for installation
For the fan to work, it is connected to a voltage of 220 V. The set also includes a seat for children. The only negative is the mandatory ventilation device.
For some, the inconvenience is the fact that the device can only be used in a sitting position. This is explained by the fact that the back of the container, in which waste is collected, opens only under the weight of a person.
#3: Dry closet BioLet 25
Made in Sweden for 3 people, this stationary ABS electric dry closet is made in Sweden. Equipped with fan, automatic compost mixing function. Sanitary equipment dimensions - 550 x 650 x 710 mm. Height from base to seat: 508mm.
The power consumption of the plumbing system is 20 - 35 W. The set includes the actual toilet, pipes, catalyst. An extraction system is required for correct operation.
Inside the structure, all biomass must be in a homogeneous state. To do this, the compost and waste are regularly mixed by automatically switching on the agitator. Switching on occurs when the lid is raised and lowered. At the same time, oxygen enters
During mixing, some part of the dry processed product spills into the tray through the grate. The compost mass is blown by a fan. Vapors and odors escape through the ventilation system. In case of liquid accumulation in excess of the norm, the float switch automatically starts the air blower.
The thermostat can also adjust the liquid level manually by adding or lowering degrees inside.
Do-it-yourself peat toilet for a summer residence

Looking at a photo of home-made peat toilets at a powder-closet cottage, it is easy to visually develop a plan for making it yourself. To correctly determine the design, first choose the location of the toilet in the country. The lack of a cesspool allows you to put the toilet seat anywhere. Usually in the country, a room is allocated for a toilet inside the house or a street booth is placed.
The chair is made of wood. First, a rectangular frame is assembled from a bar. All sides are sewn up with plywood to make a box. A hole is cut in the top shelf with a jigsaw. To finish it, it is convenient to use a plastic cover removed from an old toilet bowl.
The storage tank is made from a plastic bucket. A hole is drilled from below, the fitting is fixed and a hose is put on to drain the liquid.The bucket is inserted into the cut hole, tightly covered with a lid.
The toilet seat is fixed to the floor of a booth or a designated room inside the house. An additional container with peat and a spatula is installed nearby. Drainage hose lead to the street. The room is ventilated.
Features of the functioning of toilet cubicles
What does a peat dry closet consist of
A dry closet is one of the types of toilets in which waste disposal is carried out at the expense of organic substances - peat, sawdust and special liquids. Dry closets process waste into safe waste for the environment and health.
The device consists of two plastic cabins and storage tanks. The upper part in shape and size resembles an ordinary toilet bowl, from where the waste enters the storage tank, where there are sawdust, peat or a special filler. In the drive, unpleasant odors are disposed of and waste is processed into compost.
A dry closet is a safe device for the disposal of human waste. Installation of equipment is carried out in public places where there is no access to sewer pipes - in markets, train stations, recreation centers, etc.
Types of dry closets, their device, principle of operation
The most basic difference between a dry closet and a conventional one is its absolute environmental safety.
All waste that enters it is recycled. If this happens under the influence of bacteria, then processed products can not even be disposed of, there is no harm from them. When using chemicals, it is better not to pour waste onto the beds.
There are several types:
- Peat
- Chemical
- Electric
Regardless of the type, the device can be installed both indoors and outdoors. In any case, using a dry closet is much more comfortable than using a traditional wooden cabin.

The best liquids for the lower tank of a dry closet
Dry closet liquid Thetford Aqua Kem Green - an environmentally friendly drug, created on the basis of biologically active material. It is introduced into the lower chamber of the dry closet every 3-4 days. The drug continues to work at ambient temperatures up to -20 degrees Celsius, therefore it is suitable not only for home, but also for outdoor toilets.
- The liquid is bottled in one and a half liter bottles.
- The consumption rate of the drug is 75 grams per 10 liters of the volume of the lower chamber.
- Cost - from 1100 rubles per bottle.

Liquid Aqua Kem Blue
Another drug from Thetford, poured into the lower chamber. One dose of the drug is enough for 5 days of the lower chamber. Completely suppresses odors, disinfects the contents of the sump, breaks down the solid component of fecal effluents. Does not harm the environment. When introducing Aqua Kem Blue, the proportion of 75 grams of the drug per 10 liters of sump volume should be observed. Before administration, the dose of the drug is dissolved in a liter of plain water.
- Available in 2 liter containers
- The price of one bottle (2 liters) - from 1200 rubles

Application in winter
Not every toilet is suitable for use in the cold season. The portable model can be brought into a heated room if you want to continue using it, or put away for storage. Then you need to empty both tanks and clean. Rubber seals are lubricated with oil before conservation. If the pump runs on batteries, it is better to remove them.
Some dry closets are also suitable for winter time, if you need one, check this before buying. Also, at low temperatures, you will have to use special liquids for treating the tank - they act like antifreeze. A similar agent is also added to the water to prevent freezing. In winter, it is advisable to empty the tank more often and clean it - this helps to avoid the formation of frost. In especially severe frosts, you should not leave a full container with waste overnight.

How does a peat dry closet work
This unit is perfect for country houses and cottages. Let us consider in more detail what a peat dry closet is. The filler of the unit is peat. It absorbs bad odor. The filler contains no chemical additives. Excrement is processed into environmentally friendly compost. And this is a plus, because then you can use the compost as a fertilizer. The size of the dry closet is the same as an ordinary toilet bowl.
How does a modern dry closet work
Consider how peat works dry closet for a summer residence.
System device
The toilet consists of two containers. The bottom compartment is called the storage tank - waste gets there. It is located under the seat. This is a pull out container. Its volume is different - from 44 to 140 liters, but the most popular - from 110 to 140 liters. This is enough for 4 people.
The upper compartment is a tank for peat mixture. Water is not used in the dry closet. The top tank is equipped with a handle. After turning it, the peat mixture is poured into the storage tank.
The back wall is equipped with a ventilation pipe, which starts from the storage tank and goes up 4 meters. The contents of the lower compartment are always hidden by special flaps. They open when you use the toilet.
Operating principle
To choose a suitable peat toilet for a summer residence, you should understand the principle of its operation. Waste enters the storage tank, after which it is covered with peat.
This is done very simply: you need to turn the handle on the upper container in one direction - the mixture will sprinkle on one side, and then in the other direction - the mixture will sprinkle on the other side. Thus, the waste is evenly poured.
Beneficial bacteria turn feces into fertilizer. The mixture also absorbs liquid (urine). If a dry closet is used by one person, or the whole family, but only on weekends, then the mixture has time to process the substance. If you use it constantly, then peat is not able to process all the urine. For this, there is a drainage and filter system. The liquid passes through the drain into the lower compartment. There, the urine is filtered and discharged with a hose to the street. The hose is placed at an angle. You can take the hose to the compost pit.
You can do this in the following way - remove the drawer from the toilet body and pour the contents into the compost pit.
A few years later, peat with waste is processed into environmentally friendly fertilizer.
The dry closet set includes pipes and clamps. The ventilation pipe is installed vertically. Ventilation also helps to vent excess urine. Don't forget to take care of ventilation.
If the toilet is used no more than 20 times a day, then the ventilation is equipped with a hose with a diameter of 40 mm, and at the same time, ordinary draft is used.
If there are up to 60 visits per day, two hoses 40 mm and 100 mm should be installed. Uses normal traction.
If the toilet is visited more than 60 times a day, then it is worth equipping ventilation with two hoses. One hose with a diameter of 40 mm provides natural draft. The second - 100 mm - with forced ventilation.
The benefits of using a peat toilet in the country
Having understood the principle of operation of a peat dry closet, it is worth talking about the advantages of this unit.

- The main advantage of such a dry closet is environmental friendliness. Now there will be no unpleasant "aromas" in your house. The dry closet has compact dimensions and can be installed anywhere on the site.
- The mass of the dry closet is small, and carrying will not be difficult.
- Waste is processed into compost.
- Such a toilet is economical. The cost of the mixture for the toilet is low.
The consumption of a mixture of peat for peat toilets is 5-7 kg, that is, 20-30 liters, provided that 3-4 family members use it for 1-2 months.
Are there any disadvantages
Peat dry closet has its drawbacks. Together with it, a drain and ventilation are installed, so it should be placed outside the house. If you run out of filler, you should not immediately run after ordinary peat, since you should buy a special mixture for this dry closet. These are all the negative aspects that a peat dry closet has.
Types of peat toilets
There are two types of peat dry closets: portable and stationary.
Portable - these are small dry closets. They are easy to transport and easy to install. You can use them in summer cottages, on trips and even on yachts.
Stationary - these are small cabins. Inside them are cassette dry closets. To replace the filler, you just need to change the cassettes with peat inside.
There is also a tourist option. These are dry closets with bags filled with peat.
We examined the types of peat dry closets, and now you can choose the most suitable option for you. Following our advice, the installation of a peat toilet in your country house will take place without much effort.
Toilet cubicle arrangement

Toilet cubicle device
In many public places, it is not possible to equip ordinary closets, and in such cases, mobile dry closets come to the rescue. They have already become indispensable for various mass events, are widely used in organizing traveling fairs and folk festivals, and are installed in markets and construction sites.
The stationary dry closet consists of a base, to which three walls and a front panel with a hinged door are attached. On top of the structure has a roof.
The walls and all components are made of durable plastic, resistant to mechanical damage and fire. The material used for the manufacture of dry closets is well tolerated by temperature changes, does not collapse under the influence of sunlight and is resistant to aggressive chemicals. He is not afraid of corrosion, he is easy to clean and does not need regular tinting.
We watch the video, the device:
Inside the cabin is a toilet bowl, equipped with a tight-fitting lid. Under it is a storage tank into which wastes fall. This tank is particularly durable and resistant to active chemical liquids that break down all impurities in it. Ventilation is provided inside the cabin, so that unpleasant odors and harmful fumes are removed to the outside.

The small dimensions and light weight of dry closets make it easy to transport and install them in a new place. The installation of booths does not require a specially prepared site, but free access to them by special vehicles for cleaning tanks must be provided.
Prices
If we arrange dry closets of different types as prices increase, then liquid models are the most affordable in terms of the level of “capital” investments.
liquid
Portable samples with a lower tank volume of 15 to 20 liters generally cost no more than 10,000 rubles. (prices start from 4500 rubles). Although there are luxury products for which you will have to pay a little more - for example, Thetford Excellence + costs from 11,500 rubles.
Manufacturers, familiar on city streets, evaluate dry closets-cabins according to the level of equipment:
- "economy class" costs from 13,500 rubles. ("Economy class);
- for the "standard" you have to pay 3000 rubles. more;
- "comfort" will cost almost 20,000 rubles;
- "VIP" (with heating and lighting) - about 30,000 rubles.

In fact, the VIP version is a standard set of toilet facilities for an ordinary city apartment.
Peat
With peat dry closets, not everything is clear.
There are samples of Russian production, which are affordable for most summer residents. For example, Piteco 201 costs about 9000 rubles, and Piteco 505 or Piteco 506 - 5500-5600 rubles. Of course, for such products, “flushing” occurs manually, but the capacity of the storage tank is nevertheless impressive - 72 liters.
If we talk about prices for products of foreign brands, then they can cost several times higher. For example, a Finnish KEKKILA Termotoilet with a tank volume of 230 liters costs about 40,000 rubles. A sample of the "luxury class" BIOLAN Populett 200 is estimated at 65,000 rubles.

And this is only the “visible part” of the BIOLAN Populett 200
You can find peat toilets a bit cheaper, but in these cases their "performance" will be lower. The same BIOLAN has in its assortment a Komplet model with a 140-liter lower tank and a price of 22,500 rubles.or a very simple option for 12,500 rubles, which is called “Simplett”, but it already has a volume of 28 liters, while we are talking only about “solid” waste, since liquid ones are separated in the toilet seat area and discharged into their canister.

Simplett - the "smallest" dry closet in its family
Electrical
Electric dry closets can be divided into two categories.
The first, more accessible, category includes products with waste separation - liquids are discharged by a hose into a tank or into the ground.
The second category of products is the complete processing of waste products, including toilet paper. Initially, due to heating, the “excess” liquid evaporates, then the residue is burned. Moreover, in order for the residue to be homogeneous, it is “grinded” with a mixer equipped with cutting blades (as in a mixer).
The first category includes Separett toilets (from 18,000 to 55,000 rubles). The second category includes Biolet Mulltoa toilets (from 50,000 to 140,000 rubles).

This is how the biotoilets of the Biolet Mulltoa family look like
What are street country toilets, see the video:
The range of country dry closets is very large - there are plenty to choose from. And if you calculate the cost of arranging an autonomous sewage system and its maintenance, then the cost of most models will not seem excessive. Of course, we are talking only about the disposal of "black" wastewater, and "gray" wastewater (from bathing, washing dishes) can be discharged into a simple drainage well or storage tank for recycling (watering the site). But in order to make the right choice, it is worth consulting with a specialist who will take into account both the load and the particular location of the cottage.

Peat dry closet for giving
Dry closets, popular in cities, have only just begun to appear in dachas. In Russia and the countries of the post-Soviet space, the following types of dry closets are offered:
- peat composting;
- based on biologically active liquids.
In the article, we will consider the features of a peat composting dry closet, which is an ideal solution for giving. It uses a natural filler - peat mixture. This filler for peat dry closet well eliminates odors and recycles all waste into an environmentally friendly product. You can, of course, use ordinary peat, but still a peat-based odor absorber is more effective.
How is a peat dry closet arranged?
Almost all country dry closets of peat type have the same design and equipment. The main difference is the size and shape of the storage tank.
The device of a peat dry closet for giving (model "Compact")
- 1 - body;
- 2 - toilet seat;
- 3- tank cover;
- 4 - dispenser handle;
- 5 - tank;
- 6 exhaust pipe;
- 7- dispenser;
- 8 - perforated container.

A peat dry closet is a structure made of a toilet bowl and a compost bin. Details of a dry closet are made of heat-resistant and shock-resistant plastic.
The peat accumulator has a capacity of up to 10 liters, a filler is poured into it for further use of the toilet.
An exhaust (ventilation) pipe with a length of 2.5 to 4 m is used to remove odors and evaporate excess fluid from the toilet, as well as to supply oxygen to the compost mass. Ventilation should be removed as evenly as possible upwards.
The capacity of the tank is from 40 to 140 liters, and the composting process takes place in it. It is the dimensions of the compost tank of a peat dry closet that affect the installation process and the frequency of cleaning of specific models.
An exchange membrane and a drain hose are also available as an option.
The installation of a peat dry closet is carried out indoors or in a booth on the street, as it is not afraid of frost. For its normal operation, a ventilation pipe is installed and, if necessary, a hose is connected to drain the filtered liquid and an exchange membrane is placed.
The principle of operation of a peat dry closet
Peat dry closet is simple and effective in work:
- human waste entering the dry closet is sprinkled with peat or a mixture of peat and sawdust;
- the filler, covering the waste from above, prevents the spread of odor;
- the filler absorbs liquids, 1 kg of peat mixture absorbs 10 liters of liquid fraction, 90% of which is removed by evaporation through an exhaust pipe;
- with frequent use, it is recommended to remove the filtered liquid fraction through the drainage;
- the filler mixed with solid waste under the influence of air and microorganisms eventually turns into compost - a harmless and valuable fertilizer.
How to use a peat dry closet?
- Before the first use, fill the bottom of the receiving tank with 1-2 cm of peat.
- The peat mixture for the dry closet is poured into the upper tank.
- After visiting the toilet, turn the dispenser handle on the upper tank to the right and left several times to evenly distribute the peat mixture over the contents of the dry closet receiving tank.
- When the receiving tank of the dry closet is full, remove the upper part of the structure from it, and take the contents into the compost pit, where in a year you will get a compost mass enriched with fertilizers.
With the constant use of a peat composting dry closet with a tank with a capacity of 100 - 120 liters by a family of 3-4 people, it will have to be cleaned approximately once a month.
The positive aspects of using peat dry closets for giving:
- rather rare cleaning of the toilet;
- obtaining natural compost;
- can work at low temperatures.
The difficulty with peat dry closets is that these toilets are not entirely mobile, yet they need to be connected to ventilation and drainage.
Using a modern peat composting dry closet, you will always have comfortable amenities in the country and environmentally friendly compost for fertilizer.
