Polyacrylamide, abbreviated as PAM, is a water-soluble linear polymer composed of polyacrylamide monomers, appearing as white granules or powder, odorless, and easily soluble in water but not in most organic solvents. It is the most widely used flocculant, sedimentation, dewatering, and auxiliary filtration polymer in the water treatment field. By means of charge adsorption and bridging agglomeration, it aggregates fine suspended particles and colloidal impurities in water into large flocs, which then precipitate and separate quickly, significantly reducing the SS, COD, and color in wastewater. It is widely applicable in the full range of municipal wastewater, industrial wastewater, and sludge treatment.

Activated carbon filter material is a commonly used shallow-depth filtration medium in the domestic water treatment industry. It is made from high-purity, high-quality anthracite coal as raw material, which undergoes artificial selection, multiple crushing, sieving, water washing and dust removal, and drying refining. The product is black, multi-angled granular, with hard texture, stable structure, and high porosity, serving as the core underlay filter material for double-layer, triple-layer filter beds and mechanical filters. The chemical properties are inert, resistant to acids and alkalis, non-soluble, non-corrosive, and does not disintegrate or release impurities after long-term immersion in water. It is suitable for various domestic water, industrial wastewater, and recirculating water filtration systems, and is the preferred upper filter material paired with quartz sand.

Citric Acid: Also known as Citric Acid, with the chemical formula C₆H₈O₇, it is a natural organic acid found in fruits such as citrus and lemons, and is the most widely used food-grade organic acid and industrial additive globally. Market mainstream products are refined through grain fermentation technology, with high purity and good safety, complying with the national standard GB 1886.25 and the EU E330 food additive standard. The product is usually in the form of colorless transparent crystals or white crystalline powder, odorless with a very acidic taste, easily soluble in water and ethanol, with a weak acidic solution, and has excellent pH regulation, metal chelation, antioxidant, and antibacterial preservative properties. It also retains its natural characteristics.
