Septic tanks, water treatment

The septic tanks have to collect the waste water treatment and make them solid elements are deposited on the bottom of the septic tank and the liquid components are to be expelled through proper drainage in the event there is no a direct network connection, the pit should have a ventillación point that we install at a height greater than that of human beings if they do on land, and in case of being in an urban environment over the roof. OPERATION: Upon entering the wastewater on the computer, the input device 1 arrival slows and prevents agitation and suspension and decanted sludge and floating materials (fats, oils and foams) going directly into the separation zone effluent 2 .Effluent suffer at first forming a layer decanted sludge in the bottom of the tank 3. Fats and other lightweight materials (soaps, detergents, foams) density difference ascend to the surface resulting in a supernatant layer formed by the accumulation of these floating materials 4. After decanting, sludge undergo a process of anaerobic decomposition and optional organic matter present. As a result of this fermentation produces a partial liquefaction of the pretreated water lodos.Las in the stages of settling and anaerobic digestion (primary treatment), passed through a biological filter 6, filled with high-performance filter material. This material has two main functions:Physical barrier to the passage of solids that have not been separated in the settling process, thereby reducing the MES (suspended matter) it supports microorganisms (because of its high specific surface) responsible for carrying out processes aerobic digestion, whereby reducing the amount of organic matter (BOD5) present in the outlet water, ensuring the disposal of treated effluent for discharge to the receiving environment 7. The pretreated water in the stages of settling and anaerobic digestion (primary treatment), passed through a biological filter 6, in the case of Epurbloc ®, filled with high-performance filter material. This material has two main functions: It is a physical barrier to the passage of solids that have not been separated in the settling process, thereby reducing the MES (suspended matter). Due to its high specific surface, serves to support the microorganisms responsible for conducting the aerobic digestion process, whereby reducing the amount of organic matter (BOD5) present in the outlet water, ensuring the evacuation of treated effluent for discharge into the receiving environment 7. The ventilation system is responsible for high 8 evacuate fermentation gases generated in the aerobic and anaerobic processes (CO2, CH4, H2S, SO2, etc..) 5, leaving the debugger team decompression holes. It also serves to ventilate and bring to the septic tank and biological filter fresh air needed for digestion processes mentioned above. Although the processes of aerobic and anaerobic digestion will be continually reducing the volume of accumulated solids in the bottom of the unit, there is always a net accumulation of mud. The sludge accumulated at the bottom of the equipment must be removed periodically to prevent the reduced yield of purification equipment, caused by the accumulation of foam and long-term sludge
