Polyacrylamide (anion)

Use

Polyacrylamide is a polymer widely used in sand washing, which has excellent precipitant properties. The sewage of sand washing mainly contains a large amount of sediment and impurity suspended matter, and the turbidity of sand washing sewage is high. In the sand washing, polyacrylamide is mainly used as a solid-liquid separation agent, playing an important role in the process of removing sediment and suspended matter in sand-containing mud. The addition of polyacrylamide can effectively reduce the amount of sediment in the treatment pool and make the pool water clearer. Sand plants usually use rotating salons and filters to separate sand and mud and separate water and mud. However, even with these treatments, some small particles remain in the mud that can blur the color of the water. In this case, polyacrylamide can act as a dispersant to disperse these residues in the water, thus making the water quality clearer. The treated sewage can not only be recycled, and the sediment generated after treatment can be buried by the filter press, without causing pollution. In addition, polyacrylamide can also be used as a degrader to remove the residual heavy metals from the sand field Children and other harmful substances are decomposed and diluted to reduce the impact on the environment. Its application can also make for more water Resources are recycled and utilized to strengthen their contribution to environmental protection.

Usable method

1. When using, put the polyacrylamide product evenly into the stirring and rotating water, (control the stirring speed at 100-300rpm Appropriate) with 0.05-0.1% concentration of aqueous solution; diluted water generally choose tap water (or remove brine), warm water (<60℃) can accelerate the dissolution.

2. the dissolution operation should be carried out in the looking material, ceramic, stainless steel and other anti-corrosion mixing tank. Avoid iron rust.

3. Dissolved coagulant should be transported with low shear pump such as screw pump diaphragm pump; or quantitative gravity injection with valve.
