Our products are widely applied in wastewater treatment chemicals both for municipal and industrial, paper making chemicals, mining chemicals, enhanced oil recovery (EOR) and drilling mud fluids in oilfield chemicals, textile and dyeing, super absorbent polymer (SAP) resins , sugar & food, and other industries.
1. Sewage or Wastewater Treatment Chemicals
PAM can suit to more different conditions with less usage and high efficiency, generate less mud, easily treatment. So it is used separately or combined with organic flocculants.
Both municipal sewage and industrial waste water should be purified, pretreatment is essential before mechanical dehydrate to better mud performance and increase productivity of mechaneryequipments. Recommend use anionic PAM separately or combined with cationic PAM for mud dehydrate. The dosage is 2%~5% of average mud (water content 70%).
2. Potable or Drinking Water Treatment Chemicals
Potable/drinking water industry uses polyacrylamide in clarifying and dewatering processes. Several years ago only inorganic coagulants were used although today the use of organic coagulants such as polyamines have partially or totally replaced organics.
Solution methods:
PAM cannot be added into water directly, it should be made up solution at 0.1-0.3% solid content first before application. Makeup water temperature should be between 10oC and 40oC for optimum product performance. Slightly increase temperature can accelerated dissolution, but control temperature not exceed 60oC.
Following dispersion into agitated water, stirring should continue for about an hour to ensure complete dissolution.
Packing and storage:
Packaging in 25kg Kraft paper or PE bag, with inner PE lining.
Storage in dry, ventilated and coolspace. Avoid damp and rain. Avoid contact metal such as cooper and iron. The shelf life of powder is two years.
