Biological sewage for a country house

Today, almost every country house is equipped with sewage. But if in the village there is no central wastewater collection system, then the problem of their treatment arises. In this case, it is possible to build a cesspool on the site, but later it will have to be pumped out and exported waste on an assenizator machine. Another thing, if used biological sewage.

How does it work

The biological treatment station is a complex. It includes several components. Namely:

• automation unit;
• compressor;
• Four (or more) chambers: reception, aero tank, stabilization chamber of activated sludge, secondary settling tank.

At hit in the first chamber there is a separation of drains into fractions. Then, using a compressor, air bubbles are pumped into the water, and everything is pumped into the second chamber. Here the wastewater is mixed with biological sludge, and the cleaning process begins. After transferring such a suspension to the third chamber, the activated sludge stabilizes. Then the effluent passes through a secondary settling tank, where suspended particles are removed from them.

Tip! As a result, the output is almost pure water. It can be used for watering plants or drained into the nearest reservoir without harming the environment.

In biological treatment stations, all processes occur with the help of special bacteria. These microorganisms process phosphoric, nitrogen and other compounds that are found in wastewater. As a result of their vital activity, bacteria produce silt that is harmless to the environment.

Pluses stations

Before you purchase and install any equipment, every buyer wants to know about its benefits. Here are the pros:

1. Such equipment can be installed independently.
2. Stations are highly efficient. They are able to cope with large volumes of wastewater. At the same time, the purification rate reaches 98%.
3. As a result of the work of microorganisms, biological sludge is formed. It can be used as a fertilizer for garden and garden plants.
4. Equipment is easy to maintain. Once a year, it suffices to scrape off the muddy growths and clean all the pipes. Also, there is no need to use the services of ascenisation machines.
5. The station can be installed almost anywhere on the site. Modern manufacturers produce models that operate at temperatures from –30 to + 40 ° C. At the same time the station can be placed in any soil.
6. During operation, no unpleasant odors are formed. And due to the use of sealed containers, leakage does not form (with proper installation), therefore such a device can be installed near residential premises and water sources.
7. It has a long service life. If you carry out periodic maintenance work, the station will serve for fifty years or more.

But there are some disadvantages. The most important of them are the dependence on electricity and high cost. But these disadvantages are more than covered by pluses. Electricity is consumed not so much, and high costs are compensated by the lack of costs for pumping sewage and long service life.

Recommendations for selection and operation

Before you buy a sewage treatment system for your country house, you must determine its choice. The first thing you should pay attention to is the capacity or volume of the containers. Here it is worth knowing how much wastewater is generated in your home. This indicator depends on the number of permanent residents, frequency of visits by guests and the availability of equipment that uses water (dishwasher and washing machine, etc.).

Tip! It is worth acquiring a biological treatment station with a volume three times the daily discharge of waste from the family.

Also pay attention to the material used in the manufacture of the device. As a rule, plastic is used. It is durable and durable. And, of course, it is advisable to choose a station from a well-known and well-established manufacturer.

If we talk about the recommendations for operation, then there are no special requirements. The main thing is not to forget about the existence of such equipment on the site. It is necessary to periodically open the inspection hatch cover and inspect all elements. Also, carefully monitor the connection of the cable to the device, do not allow moisture to enter. In addition, it is necessary to carry out periodic pumping of accumulated sludge, this can be easily done with a deep-well pump directly to the bed. Silt is safe for the environment and even a fertilizer.
