Letâs have a look on the wide range of Effluent Sewage Treatment Plant which refers to wastes discharged into surface waters. This cleaner effluent is then used to feed the bacteria in biofilters. This plant is designed to treat the effluent coming from various sources that may otherwise be toxic / hazardous for the environment. Effluent Sewage Treatment Plant is available in some varieties such as Automatic Effluent Treatment Plant, Wastewater Effluent Treatment Plant, Fluidised Aerobic Bio Reactor Plant, and much more. The treatment of different effluents varies with the type of effluent and therefore constitutes different tasks consisting of mechanical, biological, chemical and physical process steps.
