Reconstruction Project of Raw Water Pretreatment Station of 2 * 600MW Unit in a Power Plant of Huaneng International

Raw water: Ganjiang River water

Water treatment capacity: 1500m3/h

Raw water turbidity: about 150NTU

Process before transformation: mechanical flocculation tank+inclined tube sedimentation tank

Process after transformation: high-density micro vortex flocculation sedimentation tank

Outlet water quality before transformation: 15NTU

Effluent water quality after transformation: 2NTU

Dosage before transformation: 30mg/l

Dosage after transformation: 20mg/l

Huaneng International Power Co., Ltd. is one of the largest listed power generation companies in China. According to the production water quality and volume requirements of the power plant, our company uses our company's "high-density micro vortex clarified water treatment technology" to transform the raw water pretreatment station. The original mechanical mixing flocculation is removed, and the hydraulic classification is carried out again. The inclined pipe of the sedimentation tank is removed, the high-density micro vortex inclined plate is replaced, and the transformation is completed in three phases, After the transformation, the operation is stable and the dosage is saved. At the same time, the mechanical equipment is canceled, the operation and maintenance amount is reduced, and the electricity cost is saved.
