Three using conditions of poly aluminum chloride

Poly aluminum chloride using the spray-drying method used in the water treatment of the three conditions are as follows.

Since poly aluminum chloride, home of the frame filter press technology, making the water insoluble solids below 0.3, the liquid water insoluble 0.1 or less, to ensure that the user's pipeline flow, while increasing rates of drug use, and natural sedimentation method is unattainable.

In water treatment, the degree of polymerization of basicity that directly affect the water purification effect, we use pressure-type particle spray drying method is to keep the mother liquor in the case of the original activity to improve the degree of polymerization products, but also according to different water quality, timely adjust the size of basicity. The drum drying can easily undermine the degree of polymerization, the product basicity interval is small, the water quality to adapt to very narrow.

Polyaluminum chloride in the spray drying process, since the nozzle child the mother liquor is sprayed uniformly in the drying tower, so that Al2O3 content uniformity, stability, easy control of the target range, the adsorption of colloidal particles enhance the capacity to act as agglomeration and flocculation two effects, other drying method can not be done.
