We keep pace with the times and use the new technology in recent years - ---spray drying instead of drum drying.Spray polymerized ferric sulfate has lower basicity and water insoluble matter, faster dissolution rate and higher content of polymerized ferric sulfate.We have a fully equipped laboratory, with milling, flotation, sedimentation, leaching and analysis equipment, that enables us to accurately benchmark alternate reagent suites against each other.we can make the process for different metal mining. Could arrange engineer to teach the workman on site and guarantee the clients getting the efficient result and saving cost. Our production line is fully equipped and regularly checked and cleaned to ensure that no impurities in the environment affect production.Our operators have undergone special door training and strictly abide by the operating procedures. PAC polyaluminum chloride has the advantages of good drying stability of spray, wide adaptability to water area, fast hydrolysis speed, strong adsorption capacity, large alum formation, fast density and sedimentation, low effluent turbidity, good dehydration performance, etc. Under the same water quality, the dosage of spray drying polyaluminum chloride is reduced, especially in the case of poor water quality, the dosage of spray drying products can be reduced by half compared with roller drying polyaluminum chloride, It not only reduces the labor intensity of workers, but also reduces the water production cost of users. In addition, spray drying products can ensure safety, reduce water accidents, and are very safe and reliable for residents' drinking water.
