PAM
Cationic polyacrylamide (PAM) is a linear polymer compound that, due to its various active genes, can form hydrogen bonds by affinity and adsorption with many substances. Mainly a negatively charged colloid brought by flocculation, it has functions such as turbidity removal, decolorization, adsorption, and adhesion.
It is suitable for the treatment of wastewater with high organic colloid content in industries such as dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic processing, and fermentation. It is particularly suitable for the dehydration treatment of urban sewage, urban sludge, papermaking sludge, and other industrial sludge.

Applitation
Municipal and Industrial Wastewater Treatment: Polyacrylamide flocculants are used in wastewater treatment plants to remove suspended solids and pollutants from wastewater. They are highly effective in improving the settling characteristics of solids, resulting in a clear liquid phase that can be discharged safely into the environment.
Mining: Polyacrylamide flocculants are used in mining operations to separate solid particles from liquid streams. They are particularly effective in separating clay particles and other fine solids from water, which is essential for the efficient processing of mineral ores.
Papermaking: Polyacrylamide flocculants are used in the papermaking industry to improve the retention of fine particles and fibers in the pulp. This leads to improved paper quality and reduced paper losses during the production process.
Oil and Gas Production: Polyacrylamide flocculants are used in oil and gas production operations to remove suspended solids from produced water. This improves the efficiency of downstream processes, reduces the environmental impact of produced water, and enhances the recovery of oil and gas.
Food and Beverage Production: Polyacrylamide flocculants are used in the food and beverage industry to clarify liquid products such as fruit juices, beer, and wine. They are highly effective in removing suspended solids, yeast, and bacteria from these liquids, resulting in a clear and stable product.
Advanges
1. Strong water retention: prevents rapid drying of mortar;
2. Instant: stir in cold water before use, with a fast dissolution rate;
3. Environmental protection: no VOC, formaldehyde, etc; no odor;
4. Low cost: lower cost and less dosage compared to ordinary water retaining thickeners;
5. Good workability: The consistency, anti sagging and water retention properties of the mortar in dry powder mortar are characterized by small dosage, good water retention, high cohesion, and good durability.
