Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safer for the environment.

Sewage Treatment Process

  • Preliminary Treatment: This is the first stage of sewage treatment plant process for removal of coarse solids and other large materials often found in raw wastewater. Preliminary treatment operations typically include large filtering screens, grit removal and, in some cases, breaking of large objects.
  • Primary Treatment: The main purpose of this treatment is to reduce any heavy solids (organic & inorganic) that settle to the bottom by sedimentation while oil, grease & lighter solids float to the surface by skimming. The settled and floating materials are removed and the remaining liquid may be discharged or subjected to the next stage i.e. secondary treatment.
  • Secondary Treatment: The prime objective is the further treatment of the effluent from primary treatment to remove dissolved and suspended biological matter. During secondary sedimentation, called secondary or biological sludge, are normally combined with primary sludge for sludge processing which remove biological solids. Secondary treatment may require a separation process to remove the micro-organisms from the treated water prior to discharge or tertiary treatment.
  • Tertiary/Advanced Treatment: Tertiary treatment generally follows secondary treatment and aids the removal of those wastewater constituents which cannot be removed in secondary treatment. Treated wastewater is sometimes disinfected chemically or physically (for example, by lagoons and microfiltration) prior its discharge into the receiving environment (sea, river, lake, wet lands, ground, etc.)

We also offer Package treatment plant is a method of sewage treatment which uses physical, chemical and biological processes to remove physical, chemical and biological pollutants/contaminants. Package sewage treatment plant is beneficial for the areas like small town ships, hotels, villas, restaurants in their premise. Small sewage treatment plant used in minimal land area and for small/less population.
