Polyacrylamide is generally a non-toxic product and a chemical substance, but the raw materials are toxic, so try not to contact it for a long time. If polyacrylamide is contacted occasionally, it will not harm the body, so don't worry too much. If it is contacted for a long time, it may cause local skin …
There are many polyacrylamide models, and the molecular weight of each model is also different, some products can reach more than 10 million molecular weight, and some products have only a few million molecular weight. The molecular weight of the cationic polyacrylamide is lower than the molecular weight of the anion, then how to determine …

There are many methods for water treatment, such as adsorption, chemical oxidation, electrodialysis, biochemistry and ion exchange, etc. As one of the oldest water treatment methods, flocculation precipitation is a more effective and low-cost pretreatment method. Nowadays, it has been widely used in the field of water treatment at home and abroad. The principle of …
Polyacrylamide is a polymer compound with a linear or cross-linked structure that can be obtained by polymerization. It can form high molecular weight aqueous solution when dissolved, and has good fluidity and stability. The special properties of polyacrylamide make it play an important role in many fields. Application of environmental protection 1. Sewage treatment As …

What is the pH of water? How to apply? The pH of water is the negative logarithm of the concentration of H+ in water. To wit: pH= a lg[H+] Because the H+ concentration of water is very small, it is very inconvenient in application, and the use of pH value to reflect the pH of …
Aquaculture wastewater pollutants and treatment technology Aquaculture wastewater, as a highly concentrated organic wastewater, is rich in a large number of pathogens and washed by rainwater into water bodies, which is easy to seriously cause the deterioration of groundwater or surface water quality. Due to the large amount of nitrogen, phosphorus and water-soluble organic matter …

Sludge discharge and sludge treatment technology of sewage treatment plant 1. Sludge discharge (precipitation) In the process of sewage treatment, sewage will produce sludge containing suspended matter and pollutants after passing through the primary sedimentation tank, secondary sedimentation tank and other units. These sludge will be separated from the wastewater by gravity precipitation, resulting in …
