Poly Aluminium Chloride in all form, is extensively used as an industrial coagulant and Flocculent in different industries. Different grades of PAC are available for different purposes. PAC products are used in water treatment for removal of suspended solid (Turbidity) and other contaminants such as natural organic matter from surface water, Micro - organisms and colloidal particles, silt and clay are stabilized by surface electrostatic charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum.

Pneumatic flat valve product knowledge
The series of flat valve is designed for pneumatic conveying system designed a new series of products, is currently the domestic advanced pneumatic conveying system for the special valve. The series of flat valve opening and closing action is between the valve body and the valve in a non-contact state, and the flat valve is closed, by the valve body and the O-ring seal to seal. The unique design of the internal components of the flat valve realizes the unobstructed passage of gas after the valve core is fully opened. Therefore, the long life of the flat valve. Features: Unobstructed gas flow throughout the valve; opening and closing flexible, between the valve body and the frictionless use of state; Size specifications: gas through the diameter of 25mm to 100mm; pressure 1MPa; long service life. Design features: Piston components unique design: Piston cylindrical surface with a special treatment, so to achieve high hardness and wear resistance. Action test, the piston normally open at 0.3MPa pressure, closed.
