ChemTreat has aluminum chloride available as a liquid. Corporate Video. Class 1 - 3 ; Class 4 - 5; Class 6 - 10; Class 11 - 12; CBSE. Quality. They also consume more alkalinity than alum, and hence tend to depress pH of the dosed water much more. Raw water structures differ from site to site, because of this, a range of different flocculation chemicals are supplied to customers by MWS. 16 thoughts on “Instead Alum Use Poly Aluminium Chloride Coagulant in Water Treatment” Jonalyn Madriaga says: ... Can you suggest me quantum of dosage of polyaluminium chloride against ferric alum..? +30 2310 997794 Correspondence tolkatha@chem.auth.gr & A.I. It is readily soluble in water. Operators use different charged groups … Ofthe inorganic coagulants tested, only polyaluminium chloride (PACI), ferricsulphate and ferric chloride were possible alternatives to alum. Ferric chloride is used as a precipitation agent for surface water treatment. Ferric Sulfate and Ferric Chloride. No. • The effective optimum coagulant dosages were 0.6 g/L and 0.7 g/L for Alum and ferric chloride respectively for stabilized leachate and incase of fresh leachate 0.8 g/L and 0.6 g/L for Alum and ferric chloride respectively. Evaluation and optimization of the coagulation/rapid mixing step of the water treatment process includes a variety of aspects. Phosphorus Removal Metal salts (most commonly ferric chloride or aluminum sulfate, also called alum) or lime have been used for the removal of phosphate compounds from water. Metsi Water Solutions is a leading supplier of water treatment chemicals in the Eastern Cape region of South Africa. Coagulant agent Alum Magnesium chloride Polyacrylamide Moringa oleifera1/23/2018 8 9. Ferric chloride – Effective over a wider pH range than alum. Because of this, it is normally a distant second choice to alum. Ferric Chloride vs. Cerium as Coagulant November 13, 2012. Q. Hi, I was wondering if anyone has tried to mix a small amount of cerium in with ferric chloride for waste water treatment? 102, Padmavati Complex, GIDIC Vapi - 396195, Vapi, Valsad, Gujarat. Lime (Ca(OH2)), lime soda ash (Na2CO3) and caustic … Reply. Visit BYJU’S to study the uses, physical and chemical properties, structure of Ferric Chloride (FeCl3) from the expert faculties. The ions can have charges as high as +4, but are typically bivalent (with a charge of +2.) Poly aluminum chloride is used mainly to remove color and colloidal matter in aqueous systems. Alum however, has a number of disadvantages: ♦ limited coagulation pH range: 5.5 to 6.5, This is one of the few water treatment chemicals that can sequester odors. 46 optimum pH for alum reaction was found to be between pH 4 and pH 8 (Reynolds and Richards, 1996). 24AXLPS2501A1ZZ. Ferric Chloride. (2007b) investigated the effectiveness of alum, ferric chloride, ferrous sulfate, and ferric sulfate in the removal of colour from a leachate sample at different pH conditions, pH 4, pH 6, and pH 12. Aluminum Chlorohydrate – Produces less sludge and is less corrosive than aluminum sulfate. A large proportion of chemicals supplied are Flocculants, which are used in potable and sewage water treatment. Optimal coagulant dosages are critical to proper floc formation and filter performance. Tolkou Laboratory of General and Inorganic Chemical Technology, Department of Chemistry, Aristotle University of Thessaloniki, GR-54124 Thessaloniki, Greece, Tel. Alum can be bought in liquid form or in dry form. Coagulation is an essential component in water treatment operations. Using synthetic coagulants are not economical and useful for health in developing countries. 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 … WATER TREATMENT COAGULANTS Paper Presented by : Peter Gebbie Author: ... such as ferric chloride, ferric sulphate and PFS®, are not that popular in Australia and tend be more expensive than alum on an equivalent dose basis. It was noted that reduction of the turbidity is greater by the use of ferric chloride in comparison with alum and this at lower doses. Empirical work has shown that combining alum and ferric chloride as dual coagulants does not result in a more effective coagulant.
