Features of treatment systems wastewater in the countryside

Any developer with improvement of a country house, sooner or later perplexing questions: How to arrange a local sewer system? Modern technologies allow to solve this problem in several ways. But here arises another dilemma - how to choose the system that is best suitable for you, your home, land, and most importantly - how much it will cost. After all, for choosing the best option, you need a comprehensive solution.

So, in order to outline the milestones users FORUMHOUSE you need to know first of all that, to purify waste water in two ways:

1. Anaerobic method. In this method, waste water occurs due to anaerobic bacteria, which do not require access of air.

In this method, the degree of purification can reach about 70% water and therefore the output of the sewer installation requires additional cleaning. To this end, using the field of filtration.

2. Aerobic method. In this case, wastewater is due to aerobic i.e. bacteria require the presence of air.

With this method, thanks to the forced air injection process is more rapid splitting of polluted water, which allows to achieve purity above 95%.

The first method is used in various kinds of septic tanks - from simple overflow from septic tanks of concrete rings and ending with local treatment facilities. The second method of purification used in stand-alone sewer systems - for example, a deep biological treatment plants.

Septic tank of concrete rings

This kind of local treatment plant, working on the principle of anaerobic, despite its simplicity and cheapness, however, requires a thoughtful approach. So what features can be in this type of septic tanks?

Dmitry Zadrutsky ( "Artezium" company Chief Engineer):

- While this kind of treatment plant in the area often construct their own, should take into account a number of features of this type of septic tank:

• Purification in this form occurs through the septic tank effluent overflowing from chamber to chamber. And so, as a rule, set the 3-chamber septic tanks of concrete rings.
• It is necessary to pay attention to the diameter of the rings. On this depends the volume of the septic tank. The greater the number of people staying, the greater the volume of the septic tank is needed and the number of cameras.
• If in the area a high level of groundwater, in order to avoid the infiltration of polluted water into the soil requires a better sealing of the septic tank.
• For better treated effluent can be used special bacteria, and for purification of runoff, it is recommended to arrange the filter box.

The disadvantages of this type of septic tank may include:

• The complexity of installation and a large amount of earth works;
• Unlike plastic septic tanks do not provide full sealing ring joints;
• The need to use special equipment to install a septic tank and a crane.

Although the septic tank may be disposed of toilet paper, personal hygiene products and produce from the washing sink machine, the reset of the dishwashing machine is not desirable, because fatty deposit is formed on the walls of backbone pipe. Also of note is the inability to use water for irrigation, and the need for periodic call assenizatorskaya machine for pumping the septic tank.

Local treatment facilities

To understand what processes occur in the form of a septic tank, will help us managing partner "Triton Plastik"Manufacturer septic tanks"TANK» Vladimir Pivovarov:

–If we talk about the principle of operation of septic tanks, we can say the following. Wastewater from the home devices sent by gravity through pipes into the first chamber septic tank, wherein It passes their natural separation of the lungs - fats, oily substances, organic waste and heavy components.The heavy fraction sinks to the bottom and eventually converted into yl light together with water fed into a second chamber for recycling the anoxic anaerobic bacteria, and then, if it is, and in the third camera.

A final purification is performed waste already in the filter fields, which are selected based on the absorption characteristics of the ground in the area and depth of the groundwater in the installation time.

The organic yl accumulated in the receiving chamber of the septic tank as a result of recycling heavies from wastewater are periodically disposed of by pumping through a hose assenizatorskaya machine.

It should be noted that for this type of septic tank to the mandatory filtering the Device. Since the water of the septic tank is cleaned by approximately 60-70% and it requires additional cleaning to clear the ground.

After an additional purification process the water is purified to almost 99%. However, it is not recommended to use this waste water for irrigation or other purposes.

Vladimir Pivovarov:

- When a seasonal residence, pumping is required once in 1-3 years, depending on the number of people living and usage. This can be assessed visually by opening the hatch in the septic tank before winter. When permanent residence pumping 1 time per year, or with the addition of bacteria 5-8 years time.

Under the conditions of a seasonal residence, it is necessary only once a year to produce sludge pumping out a septic tank in the preservation of it for the winter.

And with permanent residence using special backfill bacteria to intensive decomposition of sludge, about once a month, pumping is required much less often, only every 5-8 years.

In this case, a septic tank can be used for all types of soils, including non-filtering and a high water table.

The main advantages of this type of treatment facilities include:

• Long life - more than 50 years;
• Easy to operate and energy independence;

• Possibility of processing in moderate amounts of organic substances, which fall into a septic tank with waste water, for example, detergents, paper or cigarette butts;
• Durable ribbed surface of the septic tank, and its production of highly durable plastic material that increases stoykostk corrosive chemicals and seasonal temperature changes.

deep biological treatment plant

So what advantage is a similar system battery drainage and how the purification of waste water?

expert company "SBM - Group" producing autonomous systems local sewerage "YUNILOS"Beskischenko Maxim.

- The operating principle of the deep biological treatment plant based on the method of continuous cultivation of microorganisms, which occurs under the influence of oxygen or as it is called aeration method. A sewage purification is due to the activated sludge obtained from bacteria and microscopic animals.

Activated sludge - is weighted active biomass in water, carrying out the wastewater treatment process in the aeration tank. May be produced by biological purification of a large community of microorganisms rapidly oxidize organic matters.

Due to the organic substances present in wastewater and excess oxygen supplied to the plant, the bacteria begin to develop rapidly, and then glued into flakes, after which they secrete enzymes mineralizing organic pollution. When injected into the sump outlet yl cereal settles quickly, separated from purified water.

The degree of purification Photo allows using purified water for irrigation, and the resulting activated sludge in the aeration tank in its structure is very similar to a river and is a valuable fertilizer. So what causes sewage truck is not necessary.

Unlike cesspools, installation of biological treatment is not the accumulation of impurities, and their biodegradation for simple, secure connections - process water and stabilized by the activated sludge, thus no bad smell. Therefore, the station can be installed close to the house, at a distance of 2 meters, and the treated water can immediately take on the terrain without the use of after-treatment systems of the soil.

But is there any features in the operation of such a system?

Beskischenko Maxim:

- Despite the reliability of the system, there are several rules that must be followed for the efficient operation of the plant, namely:kanalizatsiyuzapreschaetsya to dispose of waste from construction, chemicals, plastics, petroleum, and other biologically degradable compounds. And if a power failure, it is necessary to reduce water consumption, as the overflow of the receiving station and the camera hit untreated wastewater into the environment. It is also necessary to make timely pumping activated sludge.

Summarizing it can be noted that the main advantages of this system are:

• The degree of purification in the current aeration units exceeds 95%, and purified water can be directed into water without additional filtration device fields;
• The station is easy to transport. Also, when the station setup is not required to conduct extensive earthworks or installed on a concrete base station and its anchors;
• The mechanical properties of the body made of expanded polypropylene allow any station set, the most "hard" ground even at very high level of groundwater;
• The durability of the station, its absolute tightness, ecological safety, resistance to corrosion, as well as to corrosive acids and bases, allows to exploit deep biological treatment system is not less than 50 years old.

How to start a variety of battery drainage?

In order to choose a local treatment facility, the consumer must first answer a few simple questions:

• How many people will live in the house constantly;
• What type of accommodation will be in your home - a seasonal or permanent;
• What amount constitutes sewage plumbing devices;
• Land area;
• Features of the soil, which will be installed treatment plant.

Vladimir Pivovarov:

–Knowing that the rate of urban water consumption is 200 liters per day per person, each user can select the desired volume of the local sewage treatment plant for your home.

Important influence the location of septic tanks in the area, the soil characteristics and the factor where the discharge of treated wastewater will be carried out. Depending on the chosen setting of the septic tank and corresponding accessories circuit. So much for the classical circuit wiring with low groundwater levels require infiltrators, drains or wells, in accordance with how you will organize the field of filtration.

Vladimir Pivovarov:

- Gardeners need to remember that planting trees closer than 3 meters of a septic tank is not permitted on the location, especially those trees that have a very strong root system. And if in the area already have wells or wells with water, the installation of a septic tank filtruyuuschey site should be at a distance of more than 15 meters from them.

To sum up, we can say that, armed with the necessary knowledge, and most importantly, clearly imagining the possibilities and the characteristics of a treatment plant, lyuboyzastroyschik can choose the most optimal system drain.
