A » Industrial wastewater pretreatment methods primarily include physical, chemical, and biological processes. Physical methods involve sedimentation and filtration, while chemical methods use coagulation and neutralization. Biological treatments include activated sludge and biofiltration, which leverage microorganisms to degrade pollutants. Each method targets specific contaminants to improve the efficiency of subsequent treatment stages, ensuring compliance with discharge regulations and protecting the environment.
