General Information AV 100 RO Antiscalant formulated for use as reverse osmosis antiscalant to control formation of inorganic scale ofcalcium, magnesium, barium, strontium, fluoride, iron and silica and fouling of membrane surfaces. AV 100 RO is thermally stable and its activity is not impaired in either acidic or alkaline solution. Theexcellent scale-inhibiting and fouling properties AV 100 RO will ensure that critical condition of membrane surfaces are maintained free of scale and fouling even when the water quality is suchthat the saturation index for hardness scale is exceeded. Composition AV100 RO is synergistic blend of sequestering agent and polycarboxylic acid. Typical Properties Appearance Sp. Gr at 25oC pH Solubility : Clear amber liquid : 1.01 - 1.2 : 2.0 - 4.5 : completely soluble in water Dosage & Feeding The dosage rates of AV 100 RO will vary according to the nature of water within the circuit to Betreated which will be influenced by feed water quality and saturation indices of various scales forming species present. AV RO is very effective indeed, it has been found to be effective even at 1 - 10 ppm, but for heavy scale water a higher dosage will be needed since there is some demand on the chemical due to stoichiometry in its action. For such systems, we suggest a range of 5 - 20 ppm to be maintained in the system at all time for excellent scale control. For best result AV 100 RO should be metered continuously using a corrosion resistant feed pump. It may be dosed directly from shipping container Handling Precautions Avoid contact with eyes or skin. In case eyes are contacted, flush with plenty of water at least for 15 minutes and get medical attention immediately. PACKAGING In plastic container with a net weight 25 kgs and 200 kgs.
