Difference Between Organic Polymer Flocculant and Inorganic Flocculant

Difference between organic flocculant agent and inorganic flocculant Compared with inorganic flocculant, the dosage of organic flocculant agent is less and the flocculation speed is faster. Due to the coexisting salts, the medium pH and environmental temperature have little influence on the sludge production. Moreover, the organic flocculant agent molecules can carry electrophilic groups. For example -COO and -OH. And it has chain, ring and other structures. This structure is favorable for pollutants to enter into flocs and has good decolorization. The chroma removal of organic flocculant agent is about 20% higher than that of inorganic flocculant. At present, polyacrylamide is widely used. It can adapt to a variety of flocculation objects, with less dosage, high efficiency, less sludge and easy post-treatment. It is often mixed with other inorganic flocculant agent, such as aluminum chloride. However, the monomer or hydrolytic and degradation products of synthetic polymer flocculants are often toxic. For example, the monomer of polyacrylamide has neurotoxicity, teratogenicity, carcinogenesis and mutagenicity. Introduction of flocculating water purifying agent ferrous sulfate There are many kinds of flocculant agent, including organic and inorganic. Today to recommend to you is a high-efficiency water purification agent. Everyday use is very common. Ferrous sulfate water […]

Application of Water Treatment Chemicals in Summer

Application of water treatment chemicals in summer The sewage treatment effect of sewage treatment plant in winter and summer was compared and analyzed. The results show that the average removal rate of COD and BOD is about 79% and 87% respectively. The effluent can meet the standard. The removal efficiency of COD and BOD had no significant difference between winter and summer. The removal effect of SS in summer is better than that in winter. The research results have important guiding significance and practical value for the design of urban sewage treatment plant. After nearly one hundred years of development, activated sludge process has made great progress in technology. Water treatment agent has become the main treatment technology of domestic sewage, urban sewage and organic industrial wastewater. This is one of the main methods to treat urban sewage. Activated sludge process is a method of artificial aeration, which makes the activated sludge evenly distributed and suspended in the aeration tank, fully contact with sewage, and under the condition of dissolved oxygen. What are the effects of water treatment chemicals on water quality? Water treatment is a series of processes to remove some unnecessary and harmful substances in water by physical […]
