Silicone defoamer-Ordos Ordos Silicone defoamer sludge is an inevitable product of urban sewage treatment. First of all, we should understand the source, nature, composition and solid content of sludge. According to the different main components contained in sludge, sludge can be divided into organic sludge and inorganic sludge. Generally speaking, cationic polyacrylamide is used to treat organic sludge, and anionic polyacrylamide is used in inorganic sludge. Cationic polyacrylamide is not suitable when the alkalinity is strong, and anionic polyacrylamide is not suitable when the acidity is strong. The solid content When the sludge is high, the amount of polyacrylamide is usually large. Welcome to Ankang Polyacrylamide Co., Ltd.!The size of the floc: too small a floc will affect the speed of drainage, too large a floc will make the floc more watery and muddy. The size of the flocculation can be determined by selecting the molecular weight of the polyacrylamide.
Ionity of polyacrylamide: For dewatered sludge, flocculants of different ionicity can be screened through a small test first, and the best polyacrylamide can be selected, so that a good flocculant effect can be obtained and medicine can be added. The amount is small, and the cost is saved. The third is to establish an emergency linkage mechanism. In the event of a pollution emergency, the two parties will jointly handle the pollution and hazards through upstream and downstream analysis and judgment, unified action, and joint disposal. The fourth is to establish a joint meeting mechanism. The joint meeting is held every six months and can be held at any time under special circumstances. The two parties shall determine the theme and agenda of the meeting before the meeting.
Floc strength: The floc should be kept without breaking under shearing action. Polyacrylamide molecular weight or selected molecular structure contributes to flocculation.
Mixing of polyacrylamide and sludge: Polyacrylamide must fully react with the sludge at a certain position of the dewatering equipment to take effect. For this reason, the viscosity of the polyacrylamide solution must be able to be fully mixed with the sludge under the existing equipment conditions. Whether the two are evenly mixed is the key factor for success. The viscosity of polyacrylamide solution is related to its molecular weight and preparation concentration.
The dissolution of polyacrylamide: good dissolution can give full play to the flocculation effect. Sometimes it is necessary to speed up the dissolution rate, then consider the concentration of the polyacrylamide solution.
