Anionic polyacrylamide liquid with 80–95% hydrolysis degree is a highly effective polymer flocculant widely used in water treatment and wastewater treatment processes. This type of polymer is produced through the polymerization of acrylamide followed by partial hydrolysis, which converts a large portion of the amide groups into negatively charged carboxylate groups. When the hydrolysis degree reaches 80–95%, the polymer contains a high concentration of anionic functional groups, giving it strong electrostatic interaction capability and excellent flocculation performance in many water treatment applications.

The 80–95% hydrolysis degree of anionic polyacrylamide liquid provides a high charge density and long molecular chain structure. These characteristics allow the polymer to efficiently destabilize suspended particles and promote the formation of large flocs. Compared with powdered polyacrylamide, the anionic polyacrylamide liquid form offers advantages such as rapid dissolution, easier dosing, and faster reaction in treatment systems. Because the product is already dispersed in liquid form, it can be diluted quickly and injected directly into treatment processes through automatic dosing equipment. This greatly improves operational efficiency in large water treatment facilities.

One of the most important applications of 80–95% hydrolysis degree of anionic polyacrylamide liquid is in municipal drinking water treatment. Natural water sources such as rivers, lakes, and reservoirs often contain suspended solids, fine clay particles, algae, and organic matter. These particles are very small and remain stable in water due to electrostatic repulsion. During the treatment process, coagulants such as aluminum sulfate or ferric chloride are typically added to neutralize particle charges. The anionic polyacrylamide liquid with 80–95% hydrolysis degree is then used as a coagulant aid to strengthen floc formation. The long polymer chains bridge multiple particles together, forming larger and heavier flocs that settle quickly in sedimentation tanks. This improves turbidity removal and enhances filtration performance.

Another important application of 80–95% hydrolysis degree of anionic polyacrylamide liquid is in industrial wastewater treatment. Many industries generate wastewater containing suspended solids, mineral particles, oils, metal hydroxides, and organic contaminants. Industries such as mining, steel production, chemical manufacturing, textile processing, and food processing require efficient flocculants to remove these pollutants before discharge or reuse. The strong negative charge and high molecular weight of anionic polyacrylamide liquid with 80–95% hydrolysis degree enable it to effectively bind fine particles together and accelerate sedimentation. As a result, the treatment process becomes more efficient and the quality of treated water improves significantly.

In the mining and mineral processing industry, 80–95% hydrolysis degree of anionic polyacrylamide liquid is widely used for tailings treatment and thickening operations. Mining tailings consist of extremely fine mineral particles that settle very slowly under natural conditions. When the anionic polyacrylamide liquid is added to tailings slurry, the polymer chains adsorb onto particle surfaces and form bridges between them. This process produces large flocs that settle rapidly in thickeners, allowing clear water to be recovered and recycled in the processing plant. Efficient tailings settling also reduces environmental risks associated with suspended solids discharge.

The sludge thickening and dewatering process is another key application of 80–95% hydrolysis degree of anionic polyacrylamide liquid. Wastewater treatment plants generate large amounts of sludge containing water and fine solids. Before disposal or further treatment, this sludge must be thickened and dewatered using mechanical equipment such as belt filter presses, centrifuges, and plate-and-frame filter presses. When the anionic polyacrylamide liquid with 80–95% hydrolysis degree is added to the sludge, it improves floc formation and enhances the release of water from the sludge structure. This results in better filtration efficiency, higher solids capture, and drier sludge cakes, which helps reduce disposal costs.

In the paper and pulp industry, 80–95% hydrolysis degree of anionic polyacrylamide liquid is used to treat wastewater containing cellulose fibers, fillers, and organic materials. The polymer promotes rapid aggregation of fine fibers and suspended solids, allowing them to settle quickly in clarification systems. This improves water reuse efficiency and reduces the environmental impact of wastewater discharge. In some cases, the polymer also helps recover valuable fibers that can be reused in the papermaking process.

Another important application of anionic polyacrylamide liquid with 80–95% hydrolysis degree is in oilfield water treatment and produced water clarification. Oil production processes often generate wastewater containing drilling solids, mineral particles, and oil residues. The polymer enhances solid-liquid separation and helps remove fine suspended solids from produced water. By improving sedimentation and clarification, the polymer supports efficient water recycling and protects downstream treatment equipment.

In addition, 80–95% hydrolysis degree of anionic polyacrylamide liquid is used in environmental protection and sediment control projects. During construction, dredging, and land development activities, large amounts of suspended soil particles can enter nearby water bodies. The polymer can be applied to flocculate these particles quickly, reducing turbidity and preventing sediment pollution in rivers, lakes, and reservoirs.

In conclusion, anionic polyacrylamide liquid with 80–95% hydrolysis degree is a highly effective and versatile flocculant used in many water treatment applications. Its high anionic charge density, long polymer chains, and strong bridging ability allow it to efficiently remove suspended solids and improve sedimentation performance. Because of its advantages such as fast dissolution, convenient dosing, and high treatment efficiency, this polymer is widely used in municipal drinking water treatment, industrial wastewater treatment, mining tailings clarification, sludge dewatering, paper industry wastewater treatment, oilfield water management, and environmental sediment control. As water treatment technologies continue to develop and environmental regulations become stricter, 80–95% hydrolysis degree of anionic polyacrylamide liquid will remain an essential chemical solution for improving water quality and protecting water resources.
