VSEP helps Shanghai automotive factory achieve a 100X reduction in C.O.D.
The wastewater from the production of automotive parts can be difficult to treat due to its varied chemical composition. This type of wastewater contains high levels of COD that need to be reduced to meet local sewer specifications. The typical treatment scheme could consist of chemical treatment followed by a lot of pre-treatment steps and eventually a reverse osmosis membrane system. This type of treatment scheme can take up quite a bit of space in a facility and have high operating costs due to the chemical addition.
