The coagulation principle of the water treatment process of the sewage treatment plant mainly involves the aggregation process of colloids and tiny suspended solids in the water. By adding chemicals to the water, the colloid particles that are difficult to precipitate in the water are destabilized a

Common water quality standards can be roughly divided into three categories: physical, chemical and biological indicators. For example, indicators such as color, temperature, and turbidity are physical indicators, PH, COD, ammonia nitrogen, total nitrogen, total phosphorus, etc. are chemical indicat

In textile manufacturing, one of the most critical steps before weaving is warp sizing—the application of a protective film or layer to yarns to improve their strength and abrasion resistance during weaving. This sizing process reduces yarn breakage and ensures smooth performance on high-speed looms. Traditionally, natural and synthetic polymers like starch, polyvinyl alcohol (PVA), and carboxymethyl cellulose (CMC) have been used as sizing agents. However, growing demands for improved performance, reduced environmental impact, and cost efficiency have paved the way for newer sizing technologies.
