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.
Types of treatment facilities
A septic tank suitable for price and characteristics can be selected from three groups.
1. Storage tanks for collection and periodic removal of effluents by special equipment.
2. Septic tanks for anaerobic wastewater treatment by 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 Leopard: reviews
Users can select the desired products from a wide range. 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 notes on leaks, but the problems are fixed. With an excess of detergents, intense foaming is possible. Some users consider the Bars-Aero septic tank the best option.
There are comments on components, in particular, on filtering through a grid, which is difficult to clean and it is advisable to have a spare one.
Distinctive features
Septic "Bars" has differences from other brands:
· the case from a spiral-twisted pipe of large thickness - 25 mm;
· the presence of air layers inside the pipe walls that retain heat inside;
· the ability to choose a model with a cast neck, shifted to the edge of the tank and the inclination of the inlet pipe specified at the request of the customer;
· treated drains can be discharged directly from the septic tank, without installing an additional pumping well;
· the cover is made with thermal insulation and has an anti-slip coating;
· internal partitions are made thin and durable.
Septic tanks: device and principle of operation
Septic tanks are designed for sedimentation and partial decomposition of domestic wastewater. They do not require power supply. Cleaning is carried out by no more than 60%, after which filtering is carried out through the soil.
Wastewater treatment facilities for a summer house and a private house do not require pumping of drains. They consist of tanks with adjacent sections, into which the liquid enters by overflow. The largest is the first - sedimentation tank. Even with the most modern method of wastewater treatment, there is always primary sedimentation, where most of the mechanical impurities are separated.
An important process in the septic tank is the biodegradation of effluents, produced in one of three ways.
1. Fermentation with a lack of oxygen.
2. Decomposition in a biofilter in the form of a bed in which microbes live in an aerobic environment, converting organics to sludge. The principle of its action is similar to the decomposition of wastewater on the soil surface, only the process occurs 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. Hard granules are covered with a film of colonies of bacteria that eat sewage. If it is not, granules perform the function of mechanical filtration, which significantly reduces the cleaning efficiency. To activate the process of decomposition of organic matter, biological products are introduced into the sewage system at least 1 time per month in some models. Together with the drains, they fall into the treatment device. The beginning of their action can be determined by the absence of an unpleasant odor. The filling should not be filled with water, and sewage comes into it in small portions.
3. Aeration tank with the mixing of effluents with air, in which aerobic bacteria decompose organic matter. In the presence of activated sludge, with the access of air, microorganisms actively multiply and eat organic matter. The process must occur continuously, otherwise activated sludge dies after 3 months. Wastewater treatment plants are used in private homes, where effluents for decomposition are supplied continuously.
The final stage of wastewater treatment is filtration. Purified water from anaerobic septic tanks enters the filtering 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, using as fertilizers.
Bars treatment devices are a line of models of different operating principles.
Storage capacity
The brand "Bars-N" is advisable to use in the country or in a country house for non-permanent residence. The volume of the tank is from 2 to 10 m 3 . Sewage flows by gravity into the storage tank through the inlet pipe. The device is sealed and the possibility of groundwater with precipitation is excluded. The tank 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 taken out by a cesspool machine.
The disadvantage is the overpriced septic tank - from 30 thousand rubles. Installation is expensive. You can save by installing it yourself.
Most of the lineup is represented by anaerobic treatment models.
Bars Eco
The Bars-Eco model of a vertical type provides space saving. 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 cameras, where the reception is the largest (50% of the volume). In it, sedimentation of mechanical impurities occurs. In the next section, the same processes for separating suspended particles proceed. Before the last stage, the effluent passes through an inert biofilter, where they undergo anaerobic decomposition and delay (without air access).
From the last section, the water enters the soil for purification.
Bars Mini
Bars-Mini septic tank - the minimum size model (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 go to soil treatment.
Bars-Bio
According to a similar principle, the Bars-Bio septic tank works. For a private house, you can choose a capacity of up to 10,200 liters. The horizontal tank is divided into three sections. Drains are collected in the middle chamber, from where, after settling by overflow through a biofilter, they enter the next chamber. Then the liquid through the pipe passes through the chamber of the primary sump to the second biofilter and to the third sump. From there, water flows by gravity or using a pump to filter into the ground.
Bars-Aero
Septic tank is a vertical capacity of two chambers. The principle of operation is different from previous models. The drains through the pipe 1 enter one of them (aeration tank) and are saturated with air using aerators 3 located at the bottom. In the tank is a bacterial storage 2, which serves as a biofilter. On its developed surface, aerobic microbes that eat sewage live and multiply. Active sludge is downloaded by airlift 4 from the bottom of the tank into the basket 5, located near the neck.
Sludge turnover 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, access to which is possible through the neck. Purified water exits through pipe 8.
Final sewage treatment takes place in the next settling tank with inclined partitions. Technical water is formed at the outlet , which can be used to irrigate the garden or dump into the ground.
Septic 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 cessation of aeration, it is recommended to reduce the discharge of effluents into the septic tank, otherwise activated sludge will be removed from the tank. They can be returned to active life if you start the aeration tank no later than in 1-2 days.
After the installation is idle, the resumption of the cleaning regime fully begins after 1-3 days. All this period the water will be purified by 70-75%. Adding bacteria to the septic tank to activate the process is not recommended. Natural processes occur in the installation.
Detergents in wastewater have time to oxidize with activated sludge, if used sparingly.
Conclusion
Septic Leopard is available in various modifications. The device is characterized by high strength and durability. It is advisable to install a turnkey septic tank, since the installers start them and restore their operability when there are malfunctions. Buyers have no comments on the drives, and the technology for more complex models should be followed to ensure high-quality treatment of sewage from pollution.
