Can anionic polyacrylamide be used as coagulant aid with ferric sulphate and polyaluminium chloride?

It is important to point out that the optimal coagulant dose can be reduced when anionic polyacrylamide is used as coagulant aid with ferric sulphate and polyaluminium chloride, thus decreasing treatment costs. 3.10. Mechanisms of the process

Does anionic polyacrylamide improve the coagulation–flocculation process?

The use of anionic polyacrylamide had little effect on this cost but improved the coagulation–flocculation process, leading to a significant increase in the settling speed and reduction in the volume of sludge produced. Table 7.

What is polyacrylamide used for?

Polyacrylamide is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. One of the largest uses for polyacrylamide is to flocculant solids in a liquid. This process applies to wastewater treatment, mining washing application, processes like paper making. Passed ISO9001, ISO14001, OHSAS18001 quality system certification 2.

How to make polyacrylamide solution?

Solution should be made up at 0.1-0.3% solid. Make-up water temerature should be between 10 o C to 40 o C for optimum product performance. Following dispersion into agitated water, stirring should be continue for about an hour. The liquid polyacrylamide are stable for one week. 5. Company Exhibition

How does polyacrylamide flocculation work?

Passed ISO9001, ISO14001, OHSAS18001 quality system certification 2. Polyacrylamide Application Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization.

How to store polyacrylamide?

Polyacrylamide Package and Storage 25kg/plastic enhanced paper bags with inner plastic bag, 25kg/PE bags.PAM polyaceylamide polymer should be storaged in a dry and cool warehouse with 24 months validity. Solution should be made up at 0.1-0.3% solid. Make-up water temerature should be between 10 o C to 40 o C for optimum product performance.
