PAM
a)Good for water treatment
b)Very useful in paper making
c) Industrial treatment and recycling.
PAM
Application
1. Industrial wastewater treatment. The effect is significant especially for wastewater with neutral or alkaline pH value, large suspended particles, high concentration and positive charge, such as wastewater of steel plants, electroplating plants, metallurgical plants and the coal washing plant.
2. Drinking water treatment. Use this product to deal with raw water, which has advantages of small dose, low-cost, no secondary pollution, etc.
3. Papermaking additive. It can used as dispersant of long fiber paper, dry strengthen agent, retention and drainage agent and flocculant for papermaking wastewater,etc
Instruction for use
1. It's very important to make the efficient dispersion during using, otherwise will cause agglomerate and "fish eyes", dissolving time will be longer.
2. Lowhardness water for use; avoid adopting such tank or pool, which will influence on water quality.
3. Improve the water temperature to accelerate the dissolving velocity, but not exceed 50°C.
4.Stirring will accelerate dissolving, but tough stirring will make the dispersant chain broken and degradation. Shipshape agitator with 200 - 500 rpm is the best choice.
5. Commonly mix the product into 0.05%-0.5%(w/w)solution as reserve.
6.Adjust the optimum dosage of product according to application condition.
