The sludge produced by the paper-making industry, due to its unique composition, is recognized within the industry as one of the difficult-to-treat sludge categories. This type of sludge is rich in a large amount of plant fibers and fine fiber fragments. It has a loose and porous structure, strong particle dispersion, and weak bonding force between fibers, making the sludge extremely difficult to dehydrate. During the actual treatment process, using conventional universal flocculation agents often fails to achieve effective agglomeration and flocculation of the sludge particles, easily causing problems such as disintegration of the flocs and poor formability. The resulting sludge cake is soft and unformed, with a high water content, failing to meet the environmental protection disposal standards. At the same time, it is prone to filtration failure, with a large amount of suspended matter and fiber fragments carried in the filtrate, which not only wastes the cost of the flocculation agent but also causes secondary pollution of the filtrate. The difficulty and cost of subsequent filtrate treatment also increase simultaneously, causing great troubles for the environmental operation and maintenance of paper-making enterprises.

The reason why traditional general-purpose agents cannot be adapted to papermaking sludge lies in the fact that their formulation design has not been optimized to take into account the high-fiber characteristics of papermaking sludge. They can only achieve basic flocculation for common sludge and cannot solve the core problems of fiber dispersion and difficulty in clustering. To address this issue, Works Chemical, based on the characteristics of papermaking industry sludge, has developed a dedicated sludge enhancer specifically for this purpose. The customized formula precisely adapts to the physical and chemical properties of papermaking sludge, completely overcoming the problem of sludge dewatering with high fibers.

Works' special sludge enhancer for paper sludge has an extremely high degree of cationic charge. It can quickly neutralize the negative charges on the surface of sludge particles, eliminate the electrostatic repulsion force between the particles, and lay the foundation for the aggregation and flocculation of sludge particles. At the same time, the product contains specific bridging and capturing components, which can strongly wrap, encapsulate long fibers, short fiber debris, and combine the dispersed fibers with sludge particles, achieving rapid aggregation and coagulation, and forming a structurally stable floc.

After being added and used, the sludge floccules in papermaking become dense and stable, and the formed sludge cakes are firm and dry, not prone to loosening or cracking. The moisture content can be stably maintained at the environmental protection standard. The filtrate is clear and transparent, without suspended impurities, completely eliminating the problem of filtration contamination and reducing the subsequent treatment cost of the filtrate. This agent is suitable for sludge produced in different process sections of papermaking wastewater, compatible with various types of filter press equipment such as plate and frame and belt, and can be put into use quickly without the need to modify the existing treatment process. The Works special sludge enhancer solves the sludge treatment problems in the papermaking industry in one step, from flocculation, dehydration to meeting the filtration standard. It overcomes the long-term pain points of papermaking sludge such as "unable to catch, unable to dry, and dirty filtrate", providing a new and efficient treatment paradigm for papermaking enterprises to achieve environmental protection compliance, reduce costs and alleviate burdens.
