The length of the polymerised chain, molecular weight and number of ionic charges is determined by the degree of polymerisation. b. CAS No. Though PAC is widely used in other countries its use in India for water purification is not appreciable. injection point should be at least one metre from the filter inlet, and as far away as possible form the filter inlet. auto controller sampling should be pre floc injection. Hence artificially In liquid PolyAC, the water-insoluble matter shall not exceed 0.2% Poly Aluminium Chloride is the product of the batch reaction between solid Aluminium Hydroxide (AL(OH) 3) and liquid Hydrochloric acid (HCI).Aln(OH)mCl 3 n-. It is also used extensively in the pulp and paper processing industry and in production of deorderant and antipresprant. 7. 15-30% lower. optimum pH and dosage needed to achieve the best performance of ferric chloride and poly aluminum chloride in coagulation process were determined. The product is dosed at a rate dependent on the pool flow rate i.e. VISION Turbidity removal efficiency still remained high when the initial turbidities of water were increased to 500 and 1000 NTU. At the top of the scale is aluminum chlorhydrate (ACH): at 83%, it … MSDS of Polyaluminium Chloride(PAC) Product Gallery 2) floc formation, sedimentation rate, processing power than traditional aluminum sulfate. Poly aluminium chloride (PAC) , the white or yellow powder, is an inorganic polymer coagulant.Compared with traditional inorganic coagulants, fengbai poly aluminum chloride flocculation precipitation speed is fast, the PH value applicable range is wide, water purification effect is obvious and non-corrosive to pipeline equipment. = 599.4 Metal hydroxides removes alkalinity Ferric Chloride FeCl 3 M.W.

Be the world's preeminent producer of water treatment agent. Liquid PolyAC shall contain water-soluble aluminium of not less than 2.16% w/w as Al or 10% w/w as Al2O3. Special care must be taken regarding mixing with products previously used in order to avoid gel formation or precipitation. It is also used in water treatment plants, clarification of industrial effluents and as a replacement for aluminum sulfate, aluminum chloride, ferric chloride, ferric sulfate and other non-polymerized conventional inorganic salts. Page No 42 At one water treatment plant in the Otway region of Victoria, polyaluminium chloride replaced alum and in so doing SO4 levels in the treated water were reduced from 27 to 4 - 5 mg/L. 8) and the adaptability of the source water temperature is superior to the inorganic coagulant such as aluminum sulfate. At the end of the stirring period, the beakers were removed slowly from the jar tester platform & the contents of the beakers were al- lowed to settle for 20 minutes. 7) handle water salinity increased less, is conducive to the ion exchange process and high purity of water. Poly Aluminium Chloride ( PAC ) Aguachem Ltd is quite possibly the cheapest Poly Aluminium Chloride suppliers in the UK. 1)purified water is better than aluminum sulfate coagulant, water purification costs compared with 15-30 % lower.

Related Links. It’s currently a bit busy. How To Look After Your Spa Water, movie buy review on flocpac There are now a number of different grades of PAC with aluminium concentrations between 9.5% and 18%. Note: a) .the cost of Poly Aluminium Chloride is twice/thrice of Alum ( roughly the cost of PAC-$0.4/ Kg) The optimum dosage level of the chemicals is governed by the reduction of turbidity. The lowest basicity commercial PAC's are about 10%; most PAC's are in the medium to high basicity range (50-70%). If you have any questions, please feel free to contact me. Classified as corrosive at higher concentrations, it is typically yellow in colour. The cost increase for the substitution of aluminium sulphate with poly aluminium chloride was in the order Powdered PolyAC shall contain water-soluble aluminium of not less than 14 ± 0.3% w/w as Al, or 30% w/w as Al2O3. At the low end of the basicity scale is ACS, with 0% basicity (which means it is not a PAC). STABILITY AND REACTIVITY Stability : As supplied Poly Aluminium Chloride is stable at normal temperatures and pressures. Before to Select Poly Aluminium Chloride, we should understand the formula chain, in the the general formula (Al n (OH) m Cl (3n-m)) x and have a polymeric structure,totally soluble in water.. 1)purified water is better than aluminum sulfate coagulant, water purification costs compared with Industrial water purification c, urban sewage treatment Poly Aluminium Chloride - PAC These compounds have the general formula (Al n (OH) m Cl (3n-m) )x and have a polymeric structure, totally soluble in water. no system should be fitted to the pools with high rate sand filtration. 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). injection runs should be sheathed and as short as possible. Poly aluminium chloride is used extensively in the food manufacturing industry as a coagulant. 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.
