Sewage treatment Unit processes used to separate, modify, remove, and destroy objectionable, hazardous, and pathogenic substances carried by wastewater in solution or suspension in order to render the water fit and safe for intended uses. Treatment removes unwanted constituents without affecting or alter...
The secondary treatment is designed to remove soluble organics from the wastewater. Secondary treatment consists of a biological process and secondary settling is designed to substantially degrade the biological content of the sewage such as are derived from human waste, food waste, soaps and detergent...
A total of 67 bacterial strains were isolated from a secondary effluents generated by sewage treatment plants. These strains were adapted to tolerate 6 mM nickel ions (Ni2+) and 10 g L1 cephalexin. Bacterial cell biomass that has more than 150 mg g1 biosorptive capacity was used for the ...
The primary treatment is a physical treatment, which removes the sewage’s stones, sand, fat, grease, etc., through mechanical treatment, such as grid, sedimentation, or air floatation. The secondary treatment is biochemical treatment, in which the pollutants in the sewage are degraded and ...
The stable secondary effluent after biological sewage treatment is a reliable water source for reuse. However, the effluent after secondary treatment still contains a considerable amount of pollutants, bacteria, etc., and needs to be equipped with advanced treatment processes such as disinfection or ...

1. Introduction The traditional sewage treatment plant is divided into three levels of treatment pro- cesses. The primary treatment is a physical treatment, which removes the sewage's stones, sand, fat, grease, etc., through mechanical treatment, such as grid, sedimentation, or air floatation....
