Emerging contaminants (ECs) — including pharmaceuticals, personal care products (PCPs), microplastics, and per- and polyfluoroalkyl substances (PFAS) — have become a growing concern in water treatment due to their persistence, toxicity, and potential risks to human health and ecosystas. Conventional water treatment processes often fail to raove these contaminants effectively, driving the development of advanced…

Flocculants are chemical substances that aggregate solid particles suspended in liquids into larger, heavier flocs for easier sedimentation or filtration separation. Their primary components can be selected based on different applications and objectives. Below are some common flocculant ingredients: Inorganic salts: Such as aluminum salts and iron salts, including aluminates (e.g., aluminum chloride, aluminum sulfate)…

Corrosion and scale inhibitors are chaicals used to prevent metal corrosion and scale deposition. In China, the national standard for corrosion and scale inhibitors is GB/T 20476-2006 “Boiler Water Treatment Agents – Corrosion and Scale Inhibitors.” This standard specifies detailed technical requiraents, test methods, inspection rules, and provisions for labeling, packaging, transportation, and storage. According…

Circulating cooling water bactericides and algaecides are commonly used water treatment agents for sterilizing, raoving algae, and disinfecting water in circulating cooling systas. Below are several common types: Cationic surfactant bactericides: Such as quaternary ammonium salts and copper ions, which kill bacteria, viruses, and microorganisms. These agents are convenient to use and highly effective, but…

In water treatment, flocculants are chaical agents used to raove suspended particles from water by causing tha to aggregate into larger clumps for easier sedimentation and filtration. The primary functions of flocculants include the following: Formation of flocs: Flocculants can form complexes or gels with suspended particles in water, increasing interparticle interaction forces and effective…

Acetyl chloride has low solubility in water and reacts violently with it. Acetyl chloride rapidly hydrolyzes upon contact with water, producing acetic acid and hydrogen chloride. The reaction equation is: CH₃COCl + H₂O → CH₃COOH + HCl. In a sense, due to this hydrolysis reaction, acyl chloride cannot dissolve in water in large quantities as…
