‘Wastewater treatment’

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.

Wastewater which contains a large amount of toxic chemical is treated well before releasing it into the environment to prevent harm to humans, animals and plants. The anaerobic process is one of the most effective and efficient biological processes for the treatment of wastewater where micro-organisms are used to degrade the organic matter. The process is undertaken in the absence of oxygen.
