I believe that is clear to everyone, the production of each product will encounter a lot of difficulties, and that the process of the production of PAC, encountered what difficulties need to be addressed, and will be for customers to produce high quality PAC? Poly aluminum chloride has its own uses advantages are widely used in industrial sewage treatment, far we produce polyaluminum chloride PAC has years of experience, Now PAC process for production use, encountered difficulties with you to explain : 1, PAC produced product purity is difficult: alumina content is an important indicator of the poly aluminum chloride products. Generally considered that its content is higher, the higher the purity, the better the quality. Poly aluminum chloride is widely used in industrial wastewater treatment, and did not have much content requirements, but in the paper industry polyaluminum chloride of high purity requirements are particularly high in this regard is not only difficult, but also one of the focus. The white poly aluminum chloride to occupy a certain position, is widely used in the paper industry. 2, the production the PAC difficult of insolubles difficult: the national standard commercially available poly aluminum chloride insoluble content was clear and prescribed. Production of poly aluminum chloride PAC is generally used in the minerals as raw materials, the general composition of minerals and other raw materials are complicated and subject to the broken addition powder, and the finer the powder, the higher the rate of alumina dissolution, but the corresponding insolubles and other miscellaneous harder it precipitation, how to effectively reduce the insoluble matter is urgent need to solve the difficult problems of production of PAC. 3, the production of poly aluminum chloride difficult of heavy metals and other harmful ions removal problem: certain raw materials, such as heavy metals on the high content of harmful ions, sodium sulfide, calcium sulfide, acid soluble process of harmful ions generated sulfide precipitation and removal; consider the aluminum shavings replacement and activated carbon adsorption to remove heavy metals and other harmful ions. Believe that after years of combat experience, we have gradually overcome difficulties, to produce the best quality products for our customers, we will be the most favorable prices, contributed to the long-term cooperation of the new and old customers, a series of purifying agent for you options: PAC, polyacrylamide, PFS, liquid ferric chloride efficient water purifying agent, where necessary, where there is BK! http://www.bkjsj.com PAC anionic polyacrylamide http://www.bkscl.com poly aluminum chloride multi-faceted hollow ball http://www.bkels.com pebbles
