Homesecondary treatment of wastewater

The sewage treatment plants are not equipped enough to deal with such a large amount of sewage waste. There are only a limited number of sewage plants across the country.

The process mainly contained three stages namely: Primary treatment, Secondary Treatment, and Tertiary Treatment. In the primary treatment, large objects, solids are screened using filters and removed. In the secondary treatment, more solid particles and organic matter present in the wastewater is removed using biological treatment. In the tertiary process, disinfection or chlorination takes place to make the effluent good enough to be released or reused.
