Polyacrylamide Extensive Attention
Aug 04, 2017

Sludge is the inevitable product of sewage treatment, Polyacrylamide first of all we should understand the source of sludge, nature, composition and solid content. According to the sludge contains the main components of different sludge can be divided into organic sludge and inorganic sludge. In general, cationic polyacrylamide for the treatment of organic sludge, anionic polyacrylamide for the treatment of inorganic sludge, alkaline is very easy to use cationic polyacrylamide, and acidity should not use anionic polyacrylamide, Polyacrylamide When the solid content of mud is high, the amount of polyacrylamide is usually large.

Cationic polyacrylamide ionization options: for the dewatering of the sludge, can be different degrees of flocculant through a small experiment to filter, Polyacrylamide select the best suitable polyacrylamide, so that you can get the best flocculant effect, and Can make the least amount of drugs, cost savings.

Polyacrylamide mixed with the sludge: polyacrylamide in the dehydration of a certain location and the sludge must be fully reacted, the occurrence of flocculation. To this end, the viscosity of the polyacrylamide solution must be appropriate, in the existing equipment conditions can be fully mixed with the sludge, Polyacrylamide the two mixed even if it is a key factor in success. The viscosity of cationic polyacrylamide solution is related to its molecular weight and formulation concentration.

Cationic polyacrylamide dissolved: dissolved in order to play a full play flocculation. Sometimes need to speed up the dissolution rate, then consider increasing the concentration of polyacrylamide solution.

Potatoes, sewage treatment, potatoes, also known as potatoes, Polyacrylamide potato starch wastewater is potato starch and related starch chemical products produced in the production process of waste, the food industry is one of the most polluted wastewater.

Wastewater contains a lot of organic matter,Polyacrylamide such as sugars, proteins, etc., resulting in wastewater COD, turbidity and color are high, if the direct discharge of waste water is not only a waste of water resources.

But also cause serious pollution to the environment. Directly discharged into the water of the organic matter will be in the natural fermentation after the release of hydrogen sulfide, ammonia and other gases to pollute the environment.

In the water due to the high concentration of organic matter, Polyacrylamide a variety of microbial growth and rapid propagation, which harmful microbes or pathogens a large number of growth and reproduction, Polyacrylamide not only directly against the aquatic animals, and because of microbial growth and organic matter oxidation,

Dissolved oxygen in the water is depleted, so that aquatic animals died due to lack of oxygen, thus causing serious pollution to rivers, reservoirs and the environment. For the treatment of potato starch wastewater,

People are trying to develop a reasonable, Polyacrylamide efficient and low energy consumption of starch wastewater treatment methods. At present, Polyacrylamide in the process of wastewater pretreatment coagulant or primary flocculant water-soluble polymer in the water treatment has attracted wide attention.
