What are the effects of water treatment agents on water quality?
"Water treatment" is the process of removing some unwanted and harmful substances in water by physical and chemical means, and is the process of sedimentation, filtration, coagulation and flocculation of water for specific purposes. , as well as the process of water quality conditioning such as corrosion inhibition and scale inhibition. .
Because social production and life are closely related to water, the application range involved in the field of water treatment is very wide, which constitutes a huge industrial application. .
There are two types of water treatment: sewage treatment and drinking water treatment. Commonly used water treatment agents are: polyaluminum chloride, polyferric sulfate, composite flocculant, polyacrylamide, COD remover, activated carbon and various filter materials, etc.
Commonly used water treatment methods are: (1) sediment filtration method, (2) hard water softening method, (3) activated carbon adsorption method, (4) deionization method, (5) reverse osmosis method, (6) ultrafiltration method, (7) Distillation method, (8) Ultraviolet disinfection method, etc. .
What are the characteristics of the water that has been purified by water treatment chemicals?
1. The purified water quality is better than that of aluminum sulfate flocculant, and the cost of purified water is 15-30% lower than that. .
2. The formation of flocs is fast and the settling speed is fast, and the processing capacity is larger than that of traditional products such as aluminum sulfate. .
3. The alkalinity of the consumed water is lower than that of various inorganic flocculants, so no or less alkaline agent can be added. .
4. The suitable source water can be condensed in the range of PH5.0-9.0. .
5. Low corrosiveness and good operating conditions. .
6. The solubility is better than that of aluminum sulfate.
7. Less salt increase in the treated water, which is beneficial to ion exchange treatment and high-purity water production.
