The washing is very important for the extraction of sand and gravel. This process creates a large volume of polluted wastewater. Using separation equipment like a decanter centrifuge for cleaning sand washing water and gravel wash water is popular in many places, high molecular weight Anionic flocculant can help the separation quickly.
Our acrylamide residual content is less than 500ppm.
It is the high Molecular Weight and Anionic Degree Anionic Polyacrylamide use for sand making and washing wastewater treatment.
It is for wastewater flocculation sedimentation, sedimentation and clarification treatment.
Soluble in water, safe, non-toxic, hydrolytic stable, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun. It is slightly acidic, when skin contact, wash immediately with plenty of water.

Primary Effects
Instruction of polyacrylamide
Before using,dissolve polyacrylamide with tap water at a ratio of 0.1%-0.5% and stir until fully dissolved.
Do not use iron materials to stir or hold PAM, because the reaction performance of PAM will decrease when it encounters iron.
The dosage needs to be calculated through laboratory pilot tests, with the aim of achieving the aggregation of flocs and presenting the phenomenon of sludge-water separation.
It is better to use up the prepared PAM solution within 24 hours.
Products should be stored in unopened package in a dry atmosphere at temperature no higher than 35℃.
