We clean drains on a science

We clean drains on a science
The designs intended for bio sewage treatment, are called also as bioreactors, and in a complex with ponds — installations of an underground irrigation. Process can take place both in natural, and in artificial aspects. To the first carry fields of a filtration and bio ponds. Similar systems simpler and less expensive proceeding from belief of economy, after all for bacteria the soil and water — a certain habitat. Artificial complexes — aerotenka and metatenka, septic tanks and SBR — more perfect and high-speed. But about everything one after another.

Most that on there are natural filters — it is the soil and water. But they suit only slabozagryaznenny drains. When there is a lot of organic chemistry, bacteria do not cope with processing that leads to earth or reservoir rotting. To intensify process, do fields of a filtration and bioponds. the 1st represent the land lots adapted for purification of zapyatanny liquids through the sand, sandy and loamy soil horizons, carrying out function of mechanical, chemical and bio filters. Usually, it is some plots in the area from We clean drains on a science
a half to 2 hectares, with an equal horizontal surface. Though what of them about a meter, leaving approximately on as much deep into is protected by shaft from the soil which is badly carrying out water, height. Lands here remind a pie layers in what settle down as follows: from above a vegetative cover with artificially dissolved aerobic bacteria, later засыпка, occupied by already anaerobny bacteria, a filtering material: rubble and sand. Existence of 2 species of bacteria promotes effect strengthening We clean drains on a science
(there is a double cleaning). Passed via the mechanical filter and the fat-free drains on pipes pour out in the field, covering it with a layer in 20–30 cm then pass final cleaning, passing through a loose material. Already almost transparent, water on drainage system in advance established on a site gathers to the corresponding pipes, from where arrives in a collector and further — to the river or a well. Such areas are calculated on comparably large volumes of works: 1 hectare of sand it is capable to pass in day through itself 70–125 CBM, 1 hectares of sandy loam — 50–100 CBM, loam — 40–70 CBM. If your requirements are lower, it is possible to arrange underground fields of a filtration. Liquid in them arrives through raspylitelny pipes.

It is necessary to refer ability to regeneration and clarification to advantages of this technology — lands without the aid of others are restored after cleaning, and at especially intense schedule of operation it is required to them перекопка only the top layer. On the other hand, the neighbourhood with the big, stinking areas not palatably. The candidate represents the bioponds being complexes of malekhanky being reported reservoirs in what drains settle and filtrations are exposed. The system of pumps pumps over contents from the 1st pool in another. The similar organization best of all is suitable for housing estates because it is intended generally for tertiary treatment in summertime. In the winter water freezes, and "metabolism" stops.
