Integrated water treatment equipment integrates coagulation, sedimentation, filtration, drainage, backwashing, and water collection processes. This series of water purification units can operate fully automatically without personnel operation, serving as a crucial unit for the automation of waterworks management. When paired with an automatic dosing system and disinfection equipment, it can become a fully functional water purification station (plant). The integrated water purifier for potable water has a pretreatment section (fine and coarse particle separation device) and a controllable backflushing system. The internal coating of the potable water-grade integrated water purifier has no small tube design, ensuring long-term stable operation and producing water quality that meets the national standard GB 5749-2006 for Drinking Water.
