Splet02. sep. 2024 · The conventional nitrification/denitrification pathway requires 3.5 g O 2 g −1 N removed, and shortcut nitrogen removal decreases this requirement by 18% (nitrite shunt), 35% (PdNA), or 50% (PNA). As NO x removal with influent COD increases the oxygen savings benefit is reduced. SpletFiltering is the first step at any wastewater treatment system. This process involves the removal of nonbiodegradable contaminants that enter a wastewater works. 3.1.2 Chemical treatment of wastewater Another type of wastewater treatment method is chemical wastewater treatment.

SpletThe basic function of wastewater treatment is to speed up the natural processes by which water is purified. There are two basic stages in the treat- ment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed from wastewater. SpletIn Case (A), the contaminated water undergoes physical treatment and released into the environment. Case (B) utilizes additional RO units to purify and recycle the treated water, reducing by 85% the demand for inlet well water.
