water treatment chemicals

Water treatment agents are divided into flocculants, corrosion inhibitors, scale inhibitors, algicide, defoaming agents, cleaning agents, dehydrating agents, decolorizing agents, phosphorus removal agents and ion exchange resin.

Flocculants can be divided into inorganic flocculants and organic flocculants. Inorganic flocculants mainly include iron salts and aluminum salts, and organic flocculant water treatment is mainly polyacrylamide.The following is the introduction of flocculant products:

Polyacrylamide.

Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation sex, can reduce the friction resistance between liquid, by ion characteristic points can be divided into non-ionic and anionic, cationic and amphoteric ionic four types.

Action principle

A. flocculation principle: PAM for flocculation, species with quilt wadding condensation surface properties, especially the potentiodynamic, viscosity, turbidity and PH value of slurry, zeta potential on the surface of the particles, particle polymerization is to join the cause of surface charge instead of PAM, can lower the potentiodynamic and condensation.

B. Adsorption viaduct: PAM molecular chains are fixed on different particle surfaces, forming a polymer bridge between each particle, which causes the particles to form aggregates and settle down.

C. Surface adsorption: various adsorption of polar group particles on PAM molecules.

D. Enhancement effect: the molecular chain of PAM and the dispersed phase, through various mechanical, physical and chemical functions, will be associated with the dispersed phase, forming a network, thus enhancing the function.

Features and USES

Polyacrylamide has a long molecular chain, which allows it to bridge between particles, pulling them together and settling quickly;Polyacrylamide can greatly reduce the energy required by the fluid through the pipeline.So polyacrylamide is widely used in many fields.The first four major users of polyacrylamide in China are oil fields, water treatment, paper making and mineral processing.The applications of water treatment are: municipal, printing and dyeing, food, alcohol, metallurgy, electroplating, leather, coal washing, paper making, municipal sewage, steel, ceramics, river desilting, etc.
