ддллралралдп Quality water, mainly depends on the environmental hygiene. Economic activities - industrial production, agriculture, domestic and industrial waste entering the environment, all of this may be adversely on the quality of water consumed. Septic tanks used in mechanical wastewater treatment: Septic tanks giving pure silt 1 horizontal tanks 2 vertical sumps 3 circular tanks Sumps giving recycled sludge 1 Septic 2 Bunk Or septic tanks Escher

ддллралралдп The goal is to release the biological purification of waste water from organic matter. Soil biological methods of sewage treatment fields filtering field irrigation Public field irrigation

ддллралралдп The main objective of the sanitary - topographic survey WWTP is to identify violations of sanitary requirements for maintenance and operation of the territory, individual buildings, sewage treatment plant as a whole and SPZ. Sanitation inspection should include checking the correctness of the device, maintenance and operation of treatment facilities, additional cleaning, decontamination and disinfection of wastewater and sludge. Sanitary and epidemiological survey is performed in order to determine the effect on the incidence of sewage treatment plant personnel and the population living near the intestinal infections and geohelminthiasis. Types of sanitary sewage treatment plant survey
