: . : bcrccr b >As municipal sewage treatment requirements become higher and higher, moisture content has always been a strict indicator for each sewage plant. In many cities in the south, plate and frame filter presses have been selected as the The first choice of dehydrators, although low in efficiency, is indeed excellent in terms of moisture content requirements, and has also become the first choice tool for acceptance standards. After the above introduction, during the sludge dehydration process, the selection of cationic polyacrylamide flocculant is also the main point that determines the moisture content. If the flocculant is not selected properly, it will cause severe poor dehydration effects and damage to the filter cloth. It is very large, which reduces the life of the machine and increases the frequency of replacement parts, which will cause a lot of economic waste.

: . : bcrccr b >There are many types of polyacrylamide on the market. The production processes of cationic polyacrylamide are very different. Many manufacturers are producing In order to reduce costs and increase the good-looking color of polyacrylamide, some additives will be added, which have a certain degree of strong alkalinity and cause certain corrosiveness to the equipment, which cannot be found in the short term. When selecting acrylamide monomer, there is no strict control. , resulting in insufficient monomer content and insufficient cationic monomer strength. These factors will cause polyacrylamide synthesis problems. The polyacrylamide produced by our company only uses imported acrylamide, and the monomers are produced by our company. In order to achieve the best results in terms of purity and stable product quality, the workshop is a dust-free workshop with constant temperature control to ensure that the cations produced are Polyacrylamide flocculant is guaranteed to be effective and stable.

Mainly flocculates negatively charged colloids, with functions such as turbidity removal, decolorization, adsorption, and adhesion. It is suitable for organic colloid content in dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic product processing and fermentation and other industries. High wastewater treatment, especially suitable for dehydration treatment of urban sewage, urban sludge, papermaking sludge and other industrial sludge.
