<h3>What does sewage treatment mean?</h3>
To prevent water pollution from discharges of raw sewage, sewage treatment is a sort of wastewater treatment that tries to remove contaminants from sewage to generate an effluent that is appropriate for discharge to the surrounding environment or an intended reuse application. Sewage includes pre-treated industrial effluent as well as wastewater from homes, companies, and possibly other sources. There are many different sewage treatment methods available.
Decentralized systems (including on-site treatment systems) and huge centralized systems that transport sewage to a treatment facility via a network of pipes and pump stations are examples of these. Urban runoff (stormwater) from cities with combined sewers is also transported by the sewers to the sewage treatment facility. Sewage treatment often involves two main stages, called primary and secondary treatment.
