Excessive water consumption has always been a major problem of high cost and high energy consumption in papermaking enterprises. Traditional papermaking processes require a large amount of fresh water for pulp dilution, equipment cleaning and circulating system replacement, resulting in huge water resource waste and increased water cost. At the same time, excessive water usage leads to increased sewage discharge, raises the pressure of sewage treatment and environmental protection inspection, and restricts the green and low-carbon development of enterprises. Many factories attempt to improve water recycling rate simply, but the circulating water has poor cleanliness, serious impurity accumulation and excessive microorganisms, which will cause paper defects and equipment fouling after reuse, making it difficult to achieve high-rate water recycling. Shandong Ludao Energy Technology Co., Ltd. provides systematic water-saving papermaking solutions. By optimizing pulp concentration control, improving white water purification and recycling efficiency, and reducing invalid water circulation, we greatly reduce fresh water supplementation and overall water consumption. The technology ensures the cleanliness and stability of recycled water, does not affect paper forming quality and production efficiency, effectively reduces enterprise water cost and sewage discharge, helps enterprises meet green production standards, and realizes energy-saving, emission-reducing and sustainable development.
