WebFeb 21, 2024 · Often an inorganic salt of aluminum (alum) or Fe³+ is added to destabilize colloidal dispersions and create small “pin” flocs. Then a polymer is added to further flocculate the solid into large (1- to 10-mm), fast-settling flocs. Typical dosages of polymer are 0.1 to 10 ppm, and the amount required is strongly dependent on the solids ... WebILCA® was developed by PWNT as a pre-treatment flocculation for CeraMac® filtration. Coagulation is provided upstream via a static mixer or an overflow weir for chemical mixing, and the flocculation occurs in the ILCA®. It is not necessary to form large, settleable flocs for filtration by CeraMac®, so smaller pin flocs are acceptable. soft ui tailwind
