What Is Pretreatment?
Pretreatment means the treatment of wastewater by commercial and industrial facilities to remove harmful pollutants before being discharged to a sanitary sewer system. Depending on the type of business, pretreatment may include installing a grease removal device, a sand/oil separator, a dental amalgam separator, a neutralization tank, or other device designed to remove pollutants.
