Now water has been partly treated and needs to be treated further in the next step.


3)Secondary treatment:


This stage unlike the previous one is not physical in nature, but a biological treatment process. Inorganic matter that is dissolved in wastewater is removed in the secondary stage of wastewater treatment. Bacteria are used to convert colloidal and dissolved organic matter.

Secondary sludge is formed here Cheap Trevon Coley Jersey , part of which is recycled to activate the sludge process and the remaining is mixed with primary sludge and sent to the sludge digestion tank. 905 of inorganic solids are cleaned in this stage of treatment.

Disinfection agents that are used depending on the kind of water conditions are added. After water is treated with such agents, it is finally ready for reuse or safe disposal.


Owing to the benefits and need for treating wastewater, a larger number of hospitals are installing sewage treatment plants and contributing in protecting the environment from the damage of this waste.
