Civil Engineering for Domestic Sewage Treatment in El Salvador

Characteristics of Domestic Sewage: Significant fluctuations in water quality due to varying residents' living habits, high concentrations of organic matter and suspended solids in the sewage, along with small amounts of oil, detergents and pathogenic microorganisms. Direct discharge is strictly prohibited, as it will contaminate surface and groundwater, and fail to guarantee the safety of residents' drinking water supply.

Combined with the local environmental conditions, Yimei has designed and constructed simple grille tanks and equalization tanks to intercept large-particle pollutants such as debris and plastics. In the main treatment stage, the sewage is further purified through physical and biochemical processes. Sedimentation equipment is equipped at the end for mud-water separation, which can effectively purify the generated domestic sewage, thereby controlling pollution, improving the local sanitary environment and safeguarding residents' health in water use.
