How To Reduce Bod And Cod In Wastewater. Using Physico-chemical treatment of wastewater in which you try to separate colloidal particles is achieved through the addition. Typically legislation for COD discharge is from below 120 mgL in the EU to below 50 mgL in China and therefore in order to meet regulatory standards additional treatment is. While the cost of removing BOD and COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means there are nonetheless specific situations which justify the use of hydrogen peroxide. The COD measures the total material available for chemical oxidation both.
To remove BOD a wastewater treatment plant has to aerate the water which requires a lot of horsepower aka electricity. Hydrogen peroxide H2O2 has been used to reduce the BOD and COD of industrial wastewaters for many years. Wastewater with lower COD or BOD concentrations. The hydrogen peroxide will chemically attack the organics in. COD has been reduced. One way to reduce COD in water is to use coagulants and flocculants to bind sludge together.
How to reduce COD in wastewater Primary and secondary treatments remove around 75-85 COD but the hard-to-treat COD remains.
Our BIOCLENS technology can reduce the COD of wastewater depending on its speciation when the encapsulated bacteria use it as a food source during denitrification. COD has been reduced. To remove BOD a wastewater treatment plant has to aerate the water which requires a lot of horsepower aka electricity. Wastewater separation coagulation and flocculation COD removal by microbial action. Three common BOD reduction methods for wastewater treatment are. Wastewater separation techniques remove colloidal solids suspended in wastewater by coagulation and flocculation in wastewater treatment.
