When carrying out effective treatment of domestic wastewater in a country house or in a private house, the Bars septic tank, manufactured by Aqua Hold, has proven itself well.
Types of treatment facilities
A septic tank suitable for the price and characteristics can be selected from three groups.
1. Storage tanks for collecting and periodically removing wastewater with special equipment.
2. Septic tanks anaerobic wastewater treatment for 70% with soil filtration.
3. Biological wastewater treatment plants up to 98%.
The price of a septic tank is quite reasonable and depends on its volume and the amount of equipment.
Septic Bars: reviews
Users can choose from a wide variety of products. Models are produced for periodic use, as well as working continuously. From the reviews it follows that the cost is justified, since the list of advantages is quite impressive. There are comments on leaks, but the problems are fixed. With an excess of detergents, intensive foaming is possible. Some users thinkthe best option is the Bars-Aero septic tank.
There are comments on accessories, in particular, on filtering through the mesh, the cleaning of which is laborious and it is advisable to have a spare one.
Distinguishing Features
The Bars septic tank is different from other brands:
25 mm thick coiled tube body;
· the presence of air layers inside the pipe walls that retain heat inside;
· the ability to choose a model with a cast neck, offset to the edge of the tank and a slope of the inlet pipe specified at the request of the customer;
· treated wastewater can be discharged directly from the septic tank, without installing an additional pumping well;
· the lid is thermally insulated and anti-slip;
· Internal partitions are thin and strong.
Septic tanks: device and principle of operation
Septic tanks are designed for settling and partial decomposition of domestic wastewater. They do not require electricity. Cleaning is carried out by no more than 60%, after which filtration through the soil is performed.
Wastewater treatment plants for summer cottages and private houses do not require pumping out wastewater. They consist of containers with adjacent sections, into which the liquid enters by way of overflow. The largest is the first - a sump. Even with the most modern method of wastewater treatment, there is always a primary settling, where most of the mechanical impurities are separated.
An important process in a septic tank is the biodegradation of wastewater, produced in one of three ways.
1. Fermentation in the absence of oxygen.
2. Decomposition in a biofilter in the form of backfill, in which microbes live in an aerobic environment, converting organic matter into sludge. The principle of its operation is similar to the decomposition of wastewater on the soil surface, only the process takes place in a container with porous granules and air access. Due to the developed active surface, the filter volume is small, and the process is much faster than on the soil surface. Solid granules are covered with a film of colonies of bacteria that eat sewage. If it is not there, the granules perform the function of mechanical filtration, which significantly reduces the cleaning efficiency. To activate the process of decomposition of organic matter, biological preparations are introduced into the sewerage system at least once a month in some models. Together with the drains, they enter the treatment devices. The beginning of their action can be determined by the absence of an unpleasant odor. The backfill should not be filled with water, and sewage enters it in small portions.
3. Aerotank with mixing of effluents with air, in which aerobic bacteria decompose organic matter. In the presence of activated sludge, with access to air, microorganisms actively multiply and eat organic matter. The process must take place continuously, otherwise the activated sludge dies after 3 months. Purification devices have found application in private homes, where effluents for decomposition are constantly received.
The final step in wastewater treatment is filtration. Purified water from anaerobicThe septic tank enters the filtration field underground, where it slowly decomposes over a large area and goes into the ground.
Over time, insoluble substances accumulate in containers. They should be removed with drainage pumps and used as fertilizer.
Bars cleaning devices are a line of models of different operating principles.
Storage capacity
Brand "Bars-N" is advisable to use in the country or in a country house with non-permanent residence. The volume of the tank is from 2 to 10 m3. Effluent flows by gravity into the storage tank through the inlet pipe. The device is sealed and the possibility of groundwater ingress with precipitation is excluded. The container is made of low pressure polyethylene and has sufficient strength. Its weight is small, and its service life is high, due to the absence of corrosive elements and the resistance of the material to aggressive environments.
After filling the tank with liquid, the signal lamp lights up. Waste is pumped out and removed by a sewage truck.
The disadvantage is the overpriced septic tank - from 30 thousand rubles. Installation is expensive. You can save money by installing it yourself.
Most of the line is represented by models of anaerobic treatment.
Bars-Eco
The Bars-Eco vertical type model saves space. Depending on the need, you can choose a station with a capacity of 370 to 1200 liters per day.
The capacity is divided into 3 chambers, where the receiving one is the largest (50% of the volume). It is upholdingmechanical impurities. In the next section, the same processes of separation of suspended particles take place. Before the last stage, the effluents pass through an inert biofilter, where they are anaerobically decomposed and retained (without air access).
From the last section, water enters the soil for post-treatment.
Bars-Mini
Septic tank "Bars-Mini" - a model of the minimum size (1000-1600 l) contains two chambers and is equipped with a biofilter installed between them. The productivity of the device is 330-530 liters per day. Pre-treated effluents are sent to soil post-treatment.
Bars-Bio
The Bars-Bio septic tank works on a similar principle. For a private house, you can choose a capacity of up to 10,200 liters. The horizontal tank is divided into three sections. Effluent is collected in the middle chamber, from where, after settling, it flows through a biofilter into the next chamber. Then the liquid passes through the pipe through the chamber of the primary clarifier to the second biofilter and into the third clarifier. From there, water flows by gravity or with the help of a pump for filtration into the ground.
Bars-Aero
The septic tank is a vertical container of two chambers. The principle of operation differs from previous models. Effluent through pipe 1 enters one of them (aerotank) and is saturated with air using aerators 3 located at the bottom. In the tank there is a bacteria accumulator 2, which serves as a biofilter. Aerobic microbes that eat sewage live and multiply on its developed surface. ActiveSilt is downloaded by airlift 4 from the bottom of the tank to basket 5, located near the neck.
Turnover of sludge in the station is continuous. Its excess accumulates in the basket and is periodically removed. The air supply to the airlift is regulated by valve 6, which can be accessed through the neck. Purified water exits through nozzle 8.
Final wastewater treatment takes place in the next sump with sloping baffles. At the outlet, process water is formed, which can be used for watering the garden or dumped into the ground.
Septic tank "Bars-Aero" cleans wastewater by 98%. After turning off the compressor after 4-6 hours. in the septic tank begins the growth of anaerobic bacteria. Aerobic are covered with a protective film and go into sleep mode. After the termination of aeration, it is recommended to reduce the discharge of effluents into the septic tank, otherwise the activated sludge will be removed from the tank. They can be returned to active life if the aeration tank is launched no later than in 1-2 days.
After the installation is idle, the resumption of the cleaning mode in full begins after 1-3 days. Throughout this period, the water will be purified by 70-75%. It is not recommended to add bacteria to the septic tank to activate the process. Natural processes take place in the installation.
Detergents in wastewater have time to oxidize with activated sludge if used sparingly.
Conclusion
The Bars septic tank is available in various modifications. The device is highly durable and long lasting. It is advisable to install turnkey septic tanks, since installers start them upand restore performance in the event of a malfunction. Buyers have no comments on the drives, and the technology for more complex models should be observed in order to ensure high-quality wastewater treatment from pollution.
