White water purification and recycling is an important link for paper enterprises to achieve energy saving, emission reduction and clean production. Papermaking white water contains a large amount of suspended fine fibers, filler particles, residual auxiliaries and organic pollutants. Long-term accumulation of impurities will cause white water turbidity, breeding of microorganisms and slime formation, which pollute pulp quality, block nets and felts, and induce various paper defects. Unpurified white water cannot be recycled efficiently, resulting in huge waste of water resources and increased sewage treatment pressure, which increases enterprise environmental protection costs and fails to meet green production standards. Traditional white water treatment methods have low filtration precision and cannot remove micro impurities efficiently. Shandong Ludao Energy Technology Co., Ltd. provides efficient white water purification and recycling solutions. Through high-precision flocculation, sedimentation and microfiltration technology, we thoroughly remove suspended matter, organic impurities and micro pollutants in white water, restore water clarity and cleanliness, and realize high-rate white water recycling. The recovered fine fibers can be reused in production to improve raw material utilization rate, effectively reduce water consumption and sewage discharge, and help enterprises realize green, low-carbon and cost-saving standardized production.
