Biqing water free samples, technical support and after-sales service tracking, your satisfaction, my pleasure ......... sewage treatment flocculant general use PAC, PFS, ferric chloride, and pam like. Various advantages of these types of flocculants are: 1, PAC: adaptable to all kinds of water quality, the high turbidity of the water flocculation effect is particularly significant, PH value is applied in the range of 5-9. For low-temperature treatment results were better, alum flocculation form a block, dense and heavy particles, easy settlement can shorten the settling time, low turbidity, low color, good filtration. Filtration cycle can be shortened. Containing high alumina, low dosage, you can reduce the cost of flood control. Corrosion small, in favor of the pipeline protection, easy to use, easy to store, transport, in case of deliquescence, the effect is the same. 2, polymerization ferric chloride: it is a new, high quality, efficient inorganic polymer flocculant iron salts. In flocculants can make water, sediment coagulating substance called coagulant. Commonly used mainly inorganic cationic coagulant polymer, such as hydroxy aluminum, zirconium hydroxy, these inorganic cationic polymers may dissociate in water to give hydroxyl bridge polynuclear complex ions, negatively charged and suspended solids in surface . Further, ferric chloride can also be used, aluminum trichloride and zirconium oxychloride by hydrolysis and other chemical agents, complexing, hydroxyl bridge effect, hydroxyl bridges polynuclear complex ion is formed, play hydroxy aluminum, zirconium hydroxy same effect. Coagulant is not used, the better. Multicore the bridging hydroxyl ion concentration is too high because of coagulant will sediment surface adsorption excess iron ions are positively charged, resulting in the loss of its iron coagulation effect. Therefore, there should be a coagulant used optimum concentration. With coagulant use, so that its purifying effect increased, reducing the amount of substance called coagulant. Coagulant are mostly water-soluble polymer. Polymer molecules (or association of molecules) can sediment particles are coalesced together coagulant further coalescence, thus speeding up the pace of its coagulation. Commonly used coagulant has partially hydrolyzed polyacrylamide, sodium carboxymethyl cellulose and sodium alginate. Similarly, the coagulant is not used, the better. Because coagulant exceeds a certain concentration, it can form a network structure in the water, but prevents sediment particle coagulation. Therefore, the use of coagulant is also one of the most appropriate concentration.
