The product is dosed at a rate dependent on the pool flow rate i.e. efficiency of Alum and Poly Aluminium chloride popularly known as PAC in purification of water. A new inorganic polymer coagulant, poly-aluminum-silicate-chloride (PASiC), was prepared by two approaches: (1) hydroxylation of the mixture of AlCl 3 and fresh polysilicic acid in Al/Si ratios ≥5, (PASiCc); (2) hydroxylated poly-aluminum-chloride (PAC) combined with polysilicic acid aged 2 h in Al/Si ratios ≥5, (PASiCm). In potable water treatment, clarification of water using coagulating agents has been practiced from ancient times. There are now a number of different grades of PAC with aluminium concentrations between 9.5% and 18%. Previously, alum was dosed at 45 to 55 mg/L at this plant. How To Look After Your Spa Water, Pool Water Treatment Advisory Group - Polyaluminium Chloride PAC Dosing, Pool Water Treatment Advisory Group - Polyaluminium chloride (PAC) dosing. Coagulants such as alum, PAC (poly aluminum chloride), ferric chloride, ferrous sulfate etc are used and from the organic range products like poly DADMAC, polyamine and poly DCDA are used.
