Municipal surface water treatment plants (WTP), Tigris & Euphrates river clarification, industrial wastewater coagulation, and paper manufacturing sizing in Baghdad, Basra, Mosul, Wasit, and Kirkuk.
River water from the Tigris and Euphrates carries extreme suspended sediment loads, colloidal clay, and organic color, especially during seasonal spring snowmelt and autumn flash flooding. Aluminum Sulfate (Solid Alum) is the universal, cost-efficient chemical coagulant mandated by the Iraqi Ministry of Construction, Municipalities and Public Works for rapid destabilization of negatively charged colloidal silt in drinking water treatment facilities.
Our technical-grade aluminum sulfate delivers a guaranteed water-soluble Al2O3 content of 16.0% to 17.5% with ultra-low iron content (< 0.01% Fe2O3, iron-free grade), preventing water discoloration in finished distribution networks. When dissolved in raw water, trivalent aluminum ions (Al³⁺) rapidly neutralize the electrical charge of suspended silt particles, forming dense, insoluble aluminum hydroxide micro-flocs that settle rapidly in clarifiers and Lamella plate settlers.
Packaged in 50kg heavy-duty woven polypropylene bags with heat-sealed internal polyethylene liner films, the product resists atmospheric moisture absorption and caking during high-humidity periods in southern Iraq. Indus maintains strategic reserves of over 1,000 metric tons at our Baghdad Central Chemical Terminal, Erbil Heavy Yard, and Basra Port Depot, backed by full certificate of analysis (COA) per batch.
Aluminum sulfate works most effectively in a raw water pH range of 6.0 to 7.8. Because river water in central and southern Iraq is naturally slightly alkaline (pH 7.4–8.2), alum reacts rapidly to form heavy aluminum hydroxide flocs without requiring supplemental acid dosing.
Granular alum is dissolved in water inside mechanical mixing tanks to create an 8% to 15% liquid alum solution. The solution is then metered into the raw water flash mixer using diaphragm chemical dosing pumps.
Yes. Our alum conforms to EN 878 Type 1 and NSF/ANSI 60 standards, with verified low levels of heavy metals and insolubles, fully compliant with Iraqi Ministry of Health drinking water regulations.
