Pre treatment of wastewater
View：1 Add Time：2025-07-05
Wastewater pretreatment is an important step aimed at removing large particulate pollutants, suspended solids, and oily substances from wastewater. This step is crucial to ensure the smooth progress of subsequent processing. Common pretreatment methods include grilling, sand settling, oil separation, and adjusting water quality and quantity. Among them, the grille is mainly used to intercept large particulate matter, the settling sand is used to remove inorganic particles with high specific gravity, and the oil separation is targeted at oily substances in wastewater. In addition, regulating tanks are widely used for balancing and stabilizing water quality and quantity.
