Anionic Polyacrylamide Treatment Of Water After The Water Quality Is Toxic
Oct 31, 2017

Anionic polyacrylamide treatment of water, the water quality is toxic? When using anionic polyacrylamide to treat water, the user is more concerned about the quality of the treated water. To this end, we tested the toxicity of water after treatment, the test concluded that the toxicity of anionic polyacrylamide is not present, anionic polyacrylamide in the production and sales process are in line with the International Health Organization proposed poly Acrylamide standard (GB-T13940-92): Residual residues in anionic polyacrylamide Acrylamide must be controlled under the control of the amount of 0.05% or less to control the amount of treated water will be controlled at Water Treatment Purification process, acrylamide in 0.2% solute, can be directly consumed in the following. This water quality is in line with the national standard of drinking water treatment standards, which is anionic polyacrylamide non-toxic molecules of the most favorable basis for the mechanism and performance summary, please rest assured that the use of clean water.

Anionic polyacrylamide (APAM) is a water-soluble polymer. It is mainly used for flocculation and sedimentation of various industrial wastes, such as iron and steel plant wastewater, electroplating wastewater, metallurgical wastewater, coal washing wastewater and so on. Mud dehydration and so on. Can also be used for clarification and purification of drinking water. Because of its molecular chain contains a certain number of polar groups, it can be suspended by the adsorption of solid particles in the water, so that the particles between the bridge or through the charge and particles to form a large flocculation, it can accelerate the particles in the suspension Of the settlement, there is a very clear way to speed up the clarification of the solution to promote filtration and other effects.

Application areas

1. Coal preparation plant selection of polyacrylamide for coal slurry precipitation concentrated tailings filter, please use anionic polyacrylamide, non-ionic polyacrylamide, low cationic polyacrylamide.

2. Paint industry, please use anionic polyacrylamide, non-ionic polyacrylamide. Paint wastewater treatment, the traditional method is directly on the mixed wastewater for coagulation treatment, the treatment effect is not ideal, the water quality is unstable, more difficult to meet the emission standards.

3. Dairy industry waste biological treatment, sludge treatment, please select cationic polyacrylamide.

4. Electroplating wastewater containing cyanide oxide treatment Select anionic polyacrylamide, nonionic polyacrylamide, low cationic polyacrylamide.

5. Copper mining tailings wastewater treatment using anionic polyacrylamide, low cationic polyacrylamide, nonionic polyacrylamide.

Principle of action

1) flocculation principle: PAM for flocculation, and floc type of surface properties, especially the potential, viscosity, turbidity and the PH value of the suspension, the particle surface of the dynamic potential is the reason for the addition of particles to join The surface charge of the opposite PAM, can reduce the potential and cohesion.

2) adsorption bridge: PAM molecular chain fixed on the surface of different particles, the particles formed between the polymer bridge, so that particles formed aggregates and settlement.

3) Surface adsorption: PAM molecules on the polar groups of particles of various adsorption.

4) Enhancement: PAM molecular chain and dispersed phase through a variety of mechanical, physical, chemical and other effects, the dispersed phase implicated together to form a network.
