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 purifying agent. It is a by-product produced in the process of producing a rare metal product by sulfuric acid method. The appearance of ferrous sulfate water purifying agent is light green or light yellow-green crystalline solid. Adding a certain amount can adjust the pH value of alkaline water, organically combine with suspended solids in water, and accelerate sedimentation. It is mainly used in water purification and industrial wastewater treatment, and has bactericidal effect.
What are the uses of high efficiency flocculant ferric sulfate
Flocculants include organic flocculant agent polyacrylamide. There are also inorganic flocculants such as aluminum salt and iron salt. Commonly used are polyaluminum chloride, polymeric ferric sulfate, polyaluminum ferric chloride, ferric sulfate and so on. Its a complete range. The following is a brief introduction to the use of ferric sulfate.
Flocculant is widely used in the field of water treatment. It can also be used as a raw material for the manufacture of jarosite and other iron salts and pigments, an etchant for aluminum devices, a coal dyeing agent for wool fabric dyeing and cotton printing, a soil conditioner for agriculture, a catalyst for polymerization in organic synthesis, and a purifying agent for some industrial gases. It can also be used as a biocide. It can also be used for pickling of metals, especially stainless steel and copper parts. Acid pickling solution is used as an oxidizing medium for extracting useful components from ores.
