Overview of the septic tank "Leader": device, principle of operation, advantages and disadvantages

Purpose and used wastewater treatment technologies

Septic Leader belongs to the category of treatment facilities for autonomous sewer systems designed to serve private houses with permanent residence (the most popular septic tanks for a country house are described in this article).

The degree of wastewater treatment at the outlet of the Leader system is 95% or more.

This indicator corresponds to the current SNiP and sanitary rules and allows the discharge to discharge water into natural reservoirs or soil without additional treatment in the filtration fields.

It was possible to achieve a high degree of purification of sewage water in a septic tank through the use of a combination of several technologies.

The installation uses:

• gravitational separation of effluents;
• treatment with anaerobic bacteria, which ensures the primary decomposition of complex organic substances;
• deep cleaning by anaerobic microorganisms;
• neutralization of some chemical compounds, directly, in a plastic container for a septic tank (description here).

 
Integrated treatment makes it possible to reduce the concentration of any impurities contained in wastewater to levels that, in accordance with current regulatory documents, are safe for human health and the environment.

Technical characteristics of the Leader

Septic Leader is an autonomous cylindrical station, which is installed in a horizontal position on the surface of the soil or in the ground. The capacity of the septic tank is divided into four sections, in which there is a gradual and consistent purification of contaminated effluents. Each branch is connected by a system of air lifts.

Leader septic tanks can be additionally equipped with compressors that help air get into the thickness of silt deposits. This contributes to the normal development of anaerobes - microorganisms that accelerate the process of organic decay.

The standard equipment of the Leader consists of:

plastic body and internal structure;

a compressor with a pumping device-membrane, which forcibly conducts aeration of effluents;

algae or ruff;

crushed stone or limestone backfill located at the bottom of the tanks;

a set of documents (warranty + instructions for use).

Station specifications:

the compressor power of this device is 40-100 W;

per day Leader can pump from 0.4 to 3 cubic meters. m. drains;

device weight - from 80 to 200 kg;

dimensions (length / height / diameter, in mm) - 2000-2800/1500/1 200 or 2700-3600/1650/1 450.

Models of the Leader septic tank line

The company that produces such an easy-to-use installation - the Leader septic tank, produces cleaning equipment of various capacities. The units are intended not only to serve one house, they are also suitable for the use of the whole village.

Type of septic tank model	Productivity, m/cube per day	Volley discharge, l	Number of people served	price, rub.

Leader 2	1,3−2,4	2000	12	From 137500
Leader 3	2−3,6	3000	16	From 190000

The service life of septic tanks Leader is quite high. Of course, this depends on the correct installation, operation, care of the septic tank and other criteria.

How does the septic tank "Leader" work?

The device of the described equipment is extremely simple. It is shown schematically in the photo. Several cameras are housed in a single one-piece molded plastic case. The liquid flows smoothly from one chamber to another through special tubes.

• The first chamber occupies one-fourth of the entire plastic housing; it receives dirty drains entering the septic tank through the sewer pipe. In it, the dirty liquid settles and is divided into light and heavy particles. All large organic matter smoothly settles to the bottom, a light suspension floats up and is grouped there, forming a crust.
• The second compartment plays the role of a bioreactor.Anaerobic bacteria live in it, they feed on organic matter and contribute to its decomposition into the simplest elements, solid particles settle in the second chamber, which, along with gravity, could get here from the first compartment.
• The third section is the aerotank. At its bottom is a cushion of rubble. Another colony of microorganisms (aerobic bacteria) lives in it. They absorb simple organics and make wastewater cleaner and lighter. Oxygen is necessary for the normal functioning of such microorganisms. Its supply is provided by an aerator - a device similar to a perforated pipe. The gas is forced into the chamber by a compressor.
• The fourth compartment is a secondary settling tank - an intermediate link between the first aerotank and the second aerotank. The transit function is its main purpose. While dirty water flows from one section to another, heavy suspensions precipitate everywhere, sludge is removed from each section to the first chamber through a system of special pipes.
• The fifth compartment is a secondary aerotank, more powerful and efficient. Its entire space is filled with algae capable of deep cleaning. It neutralizes phosphates and acids. Algae need oxygen to survive. Its supply is provided by an aerator. It supplies oxygen through the limestone at the bottom of the compartment.
• From the fifth compartment, water flows into the last sixth compartment. The final precipitation of sludge is carried out in it, it is introduced by an airlift into the first chamber, the purified water is discharged from the Leader septic tank by gravity into the sewer ditch or forcibly into the well. From there, the treated effluents go into the ground.

Plastic body of the septic tank "Leader"

Pros and cons of a purification plant

The manufacturer, listing the technical characteristics of the Leader septic tank, notes a number of advantages of choosing their own products.

• Septic tank "Leader" can be installed in areas with a high level of groundwater.
• The design of the cleaning plant ensures its high resistance to ground pressure.
• The plastic case is not subject to rotting, it demonstrates high resistance to Russian frosts, to complete freezing of the soil.
• Once, having installed the “Leader” septic tank in your country house, you do not need to add biological materials to it.
• The Leader septic tank, the manufacturer assures, is able to work without electricity (if the outages are short-term).
• Purified water can be used for technical needs.
• Any discharges can be dumped into the septic tank: all drains after household appliances (including washing machines and dishwashers), as well as food leftovers.

Reviews of those who already have the opportunity to operate the Leader septic tank indicate the presence of certain shortcomings that are identified during its operation. In fairness, it is worth mentioning them.

• Prolonged power outages adversely affect the quality of cleaning. It's easy to explain. Bacteria that eat organic matter need oxygen, which is supplied by compresses powered by electricity.
• The main food of bacteria is organic matter, if there is no its supply, the bacteria die. That is why the "Leader" septic tank cannot be used where people live in dachas sporadically, in short trips.
• If the described treatment plant is rarely used in winter, the bacteria will quickly die out, in which case the cleaning function of the Leader septic tank will come to naught.
• In practice, treated sewage at the outlet contains nitrates in its composition, so watering the garden can be dangerous.
• During the canning of vegetables and fruits, acetic essence, salt, alkalis often get into the sewer, they have a detrimental effect on living microorganisms. Their colonies tend to self-reproduce, but this process takes two weeks. During this time, the cleaning system will run idle.
• The influx of guests over the weekend often leads to a sharp increase in discharges. If the chamber volume of the "Leader" septic tank was not correctly calculated, the system will fail, it will contribute to the appearance of a fetid odor, it will disappear only after two weeks.

Disadvantages of a treatment plant

1. Interruptions in the supply of energy for more than 24 hours worsen the quality of cleaning sewer flows due to the low supply of oxygen;
2. Long interruptions in the operation of the Leader septic tank (for example, when installed in a summer cottage) reduce the efficiency of bacteria, which leads to the appearance of odors;
3. Non-use of equipment in the winter period threatens with freezing of bacterial colonies;
4. Preservation of nitrate compounds in the purified stream does not allow the use of liquid for watering vegetable gardens.

If the user has no particular problems with power outages, and septic tank Leader is intended for installation in a country house for year-round living, then all the shortcomings are removed automatically

It is only important to remember that alkalis, acids, salts cannot be dumped into the system, as well as equipment of the required power must be selected so that it can withstand both normal and peak operation.

Installation of a septic tank Leader

Below is a schematic representation of the mounting options for the Leader septic tank.

Recommendations for installing a septic tank

• The sewage supply pipeline is best assembled from polymer pipes with a diameter of 100 mm and laid with a slope of 20 mm per meter. In the wastewater treatment scheme, when turning on the supply pipe system, it is necessary to provide a well (with a diameter of 315 mm or more with a tray for connecting pipes).
• The compressor must be placed in a heated utility room of the building in which the sewerage system is being installed; the compressor needs to be connected to the mains.
• To avoid the formation of condensate, the air duct that leads from the compressor to the treatment plant must be placed in the same trench as the supply pipe. At the same time, make a slope in the direction of the septic tank.
• The septic tank device must be located underground, after making a base for it from compacted sand.
• The discharge pipeline must also be laid at a slope (at least 5 mm per meter).
• The sewage treatment plant must be filled with water up to the level of the drain pipe.

Commissioning of the septic tank Leader

• at the beginning of the operation of the septic tank, the average daily air temperature should be at least 12 degrees Celsius;
• the temperature of the water entering the sewage treatment plant must be at least 15 degrees Celsius.

Control of the septic tank

• mandatory actions include regular monitoring of the degree of aeration, which must coincide with that indicated in the data sheet;
• comply with the operating conditions of the compressor (in accordance with the passport for the product);
• timely perform maintenance of the septic tank;
• prevent chlorine and oil-containing substances from entering the treatment plant.

forced option

Maintenance of a septic tank Leader

• empty the receiving chamber (septic tank) once a year with a sewer;
• brush loading - once a year, rinse with a stream of water;
• excess sludge periodically (1 time in 3-6 months) is pumped by airlifts into the receiving chamber - septic tank;
• crushed lime in the aerotank of the 2nd stage to replenish 1 time in 3 years;
• weirs and walls of the body should be cleaned once every 3 years.

The septic tank compressor Leader supplies air to the aerators and inside the septic tank there is aeration (seething) and oxygen supply of biological organisms (bacteria). The compressor is installed in the technical room, and the air is supplied through a separate tube (metal or plastic).

In fact, I can’t say anything good or bad about the septic tank, the only thing that confuses me is that it is necessary to add crushed limestone, maybe it somehow dissolves there, but at the same time it remains inside and concretes the bottom of the septic tank.

Design

The system provides deep purification of wastewater. Inside the hull, liquid and organic waste are transported between compartments using airlifts. Cleaning is carried out by colonies of anaerobic and aerobic bacteria living on special synthetic algae made of the thinnest thread. When the oxygen compressor is on, the efficiency of the system is at its maximum level.

The first volumetric compartment is used for settling sewer waste. Large organic impurities settle to the bottom, and the liquid suspension enters the next compartment (the so-called reactor).

Bacteria that do not depend on oxygen live in a biological reactor. In the process of decay, the waste is split into small fractions. Some of them settle down.

After that, the liquid is processed in the aeration tank with the help of aerobic bacteria.Air enters this compartment through a special perforated pipe, ensuring the oxidation of organic matter and the formation of sediment. The bottom of the aeration tank is lined with small gravel, on which bacteria colonies willingly arrange.

The resulting sludge is pumped into the receiving chamber using an airlift, and the clarified liquid enters the next compartment for deep cleaning. Aerobic bacteria also function here. The compartment is provided with artificial algae and a lime bottom. An aerator is installed at the bottom. The main purpose of the compartment is to reduce the acidity of the water.

In the last compartment, purified up to 95% water is collected and once again settled, which can be used for irrigation.

Septic tank Leader at the price of the manufacturer. Sales, installation and maintenance

Septic Leader is a high-tech treatment facility with deep biological post-treatment. In fact, this is a cross between a conventional septic tank and a full-fledged autonomous aeration station.

The principle of operation of the septic tank Leader

How does a septic tank Leader work?

The standard septic tank includes:

1. septic tank
2. Bioreactor
3. Aerotank 1 stage
4. Secondary clarifier
5. Aerotank 2 stages
6. Tertiary clarifier
7. Air valve
8. Regulating valve

Consider below the principle of operation of a septic tank:

1. Drains through sewer pipes from the house enter the first chamber - the receiver. In it, their primary settling and separation in suspension take place. Large fractions sink to the bottom, and the lungs float to the surface, forming a "crust".
2. Part of the treated effluent goes into the bioreactor. Here, under the action of anaerobic bacteria, splitting from simple substances occurs.
3. From the bioreactor, wastewater flows into the aerotank, which begins to saturate them with air. As a result, organic matter is oxidized and activated sludge is formed.
4. The airlift pumps the activated sludge into the receiving compartment, and then into the deep cleaning compartment. Its main role is to reduce the acidity of treated effluents.
5. The water purified from organics enters the last chamber, where suspensions and activated sludge are removed.
6. At the output, we get up to 96% purified water, which can be discharged into the ground, reservoir, etc.

Operation and maintenance of the septic tank Leader

Proper operation and timely maintenance of the Leader septic tank is as follows:

1. Installation and commissioning are recommended to be carried out in autumn or summer, when the air t is not lower than +15. This is advised to do in order to preserve the vital activity of microorganisms in the septic tank.
2. Sewer hatches must always be closed.
3. Always observe the nominal load not exceeding 20%.
4. You can not run into a place where a septic tank is installed by vehicles.
5. Regularly, once a year, we pump out the sediment from the receiving chamber.
6. We wash the brush load once a year.
7. Excess sludge must be pumped into the receiving chamber 2-3 times a year.
8. Change the lime load once every 3 years.
9. Once every 3 years, check the weirs and clean the inner surface of the housing.

Our company will perform a full professional service of autonomous sewers Leader, which guarantees the absence of many problems with the operation of the installation in the future.

Model range Uponor Sako

In the standard line of the manufacturer - four modifications of septic tanks:

As you can see from this list, the volume of Uponor septic tanks starts from one and a half cubes and ends with four cubes. As already mentioned, this volume covers the entire segment of country houses, houses and large cottages. However, given the design features and modularity of the equipment, you can easily increase the volume capacity, thereby improving system performance.

Septic tanks of small volumes of 1.5 and 2 m3 have two settling sections. Large septic tanks of 3 and 4 cubic meters. already consist of three and four containers. These containers are supplied separately. And it's easier to install them that way. This is especially true for large cleaning systems. The volume of drains and the model of equipment is selected individually, but it should be remembered that it is always better to choose gravity systems with a margin. This will only benefit the quality of cleaning and protect the system from volley discharges when guests run over.

Overview of the range

Septic Leader is available in several versions. Each model is designed for a certain number of residents. Depending on the power, the cost of the product also differs. Here is an overview of the models that are on the market:

• "Leader 0.4" is the most budget version of the device. It is designed to service sewers, which are constantly used by 2-4 people. The septic tank handles 400 liters of sewage per day. The cost of such a device is close to 75 thousand rubles.
• If three to six people permanently live in the house, then it is better to purchase the Leader 0.6 device, you can buy it for 85 thousand rubles. Such a septic tank will cope with 600 liters of wastewater per day.
• "Leader 1", the cost of which is about 110 thousand rubles, is able to cope with 1000 liters per day. This capacity is enough to serve a house with 5-10 tenants.

More powerful products are also available. So, to serve several houses or a small hotel at once, septic tanks "Leader 1.5" and "Leader 2" are used. Such devices will cope with drains from 12 to 20 people at once. As productivity increases, so does the cost. "Leader 1.5" can be bought for about 120 thousand rubles, and for "Leader 2" you will have to pay almost 140 thousand rubles.

Thanks to a large assortment of models, it is easy to choose the right septic tank from this manufacturer. But do not save money, it is better to purchase a device with a performance margin. This will allow you not to worry about the efficiency of its work, even if numerous relatives come to you and the number of drains increases.

Characteristics of septic tanks Leader

The company in question produces septic tanks of various sizes, which have been put into mass production.

Such treatment systems are mainly intended for operation in the country, but they are also capable of servicing several cottages at the same time. These include:

Leader 0.4:

• Productivity = 0.2 - 0.5 cubic meters;
• Volley discharge = 400 l;
• Number of people = 2.

Leader 0.6:

• Productivity = 0.4 - 0.75 cubic meters;
• Volley discharge = 600 l;
• Number of people = 3.

Leader 1:

• Productivity = 0.7 - 1.2 cubic meters;
• Volley discharge = 1000 l;
• Number of people = 5.

Leader 1.5:

• Productivity 1.5 - 1.8 cubic meters;
• Volley discharge = 1500 l;
• Number of people = 7.

Leader 2:

• Productivity = 1.3 - 2.4 cubic meters;
• Volley discharge = 2000 l;
• Number of people = 12.

Leader 3:

• Productivity = 2 - 3.6 cubic meters;
• Volley discharge = 3000 l;
• Number of people = 16.

The main characteristics that must be taken into account when choosing and buying a septic tank are:

Cleaning station performance

Here it is important to know that this will significantly depend on:

• The number of people who will use it daily;
• The total amount of wastewater.

1. The size of the septic tank, when calculating which you need to know the performance, since it is this indicator that completely influences the choice of the future location for installing the station;
2. Required compressor power. This factor can affect the purification of the liquid and its efficiency, as well as the cost of the septic tank.

Advantages and disadvantages

A certified brand product has several positive qualities at once, such as:

• long service life;
• the possibility of using at a high level of groundwater;
• convenient design, providing the station resistance to ground pressure;
• reliability and safety for the environment;
• resistance to corrosion (including the effects of aggressive environments);
• resistance to frost and freezing of the soil;
• does not require the addition of additional biological materials or chemicals for proper operation;
• the complex functions even when the power supply is turned off;
• the station does not need to be additionally locked in the ground;
• small stations with a four-level cleaning system have small dimensions that allow you to install LOC near residential buildings.

But there are also disadvantages that users openly talk about in their reviews. It:

• a sharp decrease in the quality of cleaning in the event of a power outage;
• the death of bacteria only during seasonal use (in warm weather);
• the possible presence of nitrates in already filtered and purified water;
• the appearance of an unpleasant odor as a result of a malfunction of the system (for example, when a septic tank overflows);
• salts, acids and alkalis should not be drained into the sewer - this harms bacteria.

Model selection principle

Choose this type of treatment plant by consumption per day and salvo discharge. The cost per day is calculated based on the number of residents and all the procedures that they take every day.

For example. Family of 3, there is a washing machine, dishwasher, shower / bath, toilet, kitchen sink. We count how many times a drain tank can go down on average per day, multiply by its capacity, we find how much water is drained when the toilet is placed. Next, we consider how much water is spent on washing, washing dishes, washing, how often family members take a shower, bath, etc. We summarize all the data and get the number of drains per day.

You need to choose the size for a volley discharge or a daily amount of drains

Now we calculate the magnitude of the volley discharge.This is the volume that an individual sewer installation can process within 2 hours. Most often, at least, this is the volume of two bathrooms or the amount of water that the family spends during the evening/morning shower + toilet flushes + water for washing + cooking + washing dishes. This is if all these processes are going on simultaneously.

Knowing these two numbers, select a model. In the selected model, both numbers should not be less. More - easily, less - the installation is unlikely to cope. As a rule, the main criterion is a volley discharge. Since if the installation cannot cope with such an amount of water, untreated water will leave the septic tank. As professionals say, there will be sludge removal, and, accordingly, there will be a smell and related "charms".

Advantages of this septic tank

Once inside the septic tank, the effluents go through several stages of purification, which is accompanied by the separation of fractions and gradual decomposition. The process is activated by adding special bacteria to the waste. The saturation with bacteria depends on the volume of the tank and the amount of wastewater received.

The scheme of the septic tank "Cedar" allows you to consider its simple design

In addition to a simple and understandable design, the Kedr septic tank has the following advantages:

• easy installation in a small area pit;
• installation without the participation of heavy equipment;
• tightness;
• anti-corrosion material (durable plastic);
• the possibility of installation near the house (but not closer than 5 m);
• service life - 30 years or more;
• affordable price.
