For the duration of secondary treatment method, biological processes are made use of to eliminate dissolved and suspended natural issue measured as biochemical oxygen demand (BOD).
Decentralized systems treat wastewater closer to its resource, cutting down the demand on central conveyance systems and making it possible for with the reuse of addressed drinking water in irrigation and industrial processes.
