3、 Main uses
1. Sludge dewatering
According to the nature of the sludge, the corresponding molecular weight product of this product can be selected, which can effectively perform gravity sludge dewatering before the sludge enters the pressure filtration. During dehydration, large flocs are produced, which do not stick to the filter cloth and do not flow during pressure filtration. The amount used is small, and the dehydration efficiency is high. The moisture content of the mud cake is below 80%.
2. Treatment of sewage and organic wastewater
This product exhibits a positive charge in acidic or alkaline media, which can coagulate and precipitate wastewater with negative charges in suspended particles. For example, wastewater from sprinklers, breweries, monosodium glutamate factories, sugar factories, meat factories, beverage factories, textile printing and dyeing factories, etc. cationic polyacrylamide is several times or tens of times more effective than anionic polyacrylamide, non-ionic polyacrylamide, or inorganic salts, Because this type of wastewater generally carries a negative charge.
3. Flocculant treatment in water treatment plants
This product has the characteristics of low dosage, good effect, and low cost, especially when used in combination with inorganic flocculants, the effect is better. It will become an efficient flocculant for water treatment plants in the Yangtze River, Yellow River, and other river basins.
4. Paper Additives
Cationic PAM paper enhancer is a water-soluble cationic polymer containing amino formyl groups, which has functions such as reinforcement, retention, and filtration, and can effectively improve the strength of paper. At the same time, this product is also an efficient dispersant.
5. Oilfield chemicals
Polyacrylamide also has certain chemical effects in oilfield drilling and exploitation, such as being used as a clay anti swelling agent and thickening agent for oilfield acidification
