Decrease of COD Wastewater Automotive by Using Sludge Prodused by Process

Purification of wastewater´s OEM is by physicochemical methods , always industry with four continues methods: mechanical oil-skimming, neutralization and flocculation ,sedimentation ,filtration completes purification. Produced sludge in these methods is useful for purification of wastewater. We used this sludge instead of polyelectrolyte and partial lime. (by using jar test method). Then COD (chemical oxygen demand) is decreases until 50% and produces better sludge.
