Tender & Specification Inquiries

Technical & Engineering FAQs for Water Chlorination Chemicals

Direct authoritative answers for procurement officers, consultant engineers, and EPC contractors specifying Water Chlorination Chemicals in Iraq.

Why is sodium-process calcium hypochlorite preferred over calcium-process in Iraq?
Sodium-process calcium hypochlorite has significantly lower insoluble calcium residue (under 3% versus over 10% for calcium-process). This means it dissolves completely without leaving thick chalky lime sludge that clogs chemical dosing pump foot valves, injector nozzles, and dosing tanks in Iraqi treatment plants.
What safety features are built into Indus chlorine gas ton containers?
Containers feature dual forged bronze valves protected by heavy steel hoods, and multiple fusible safety plugs that melt at 70°C to relieve pressure during an external fire, preventing vessel explosion. Indus also provides emergency Chlorine Institute "B-Kit" containment hoods that encapsulate valves in the unlikely event of a stem leak.
How should sodium hypochlorite liquid be stored during the hot Iraqi summer?
Liquid sodium hypochlorite naturally decomposes into sodium chloride and oxygen when exposed to heat and sunlight. It must be stored in shaded, well-ventilated chemical storage areas below +25°C away from direct sunlight and acids. Indus provides fresh, stabilized stock directly from regional warehouses.
What is the advantage of 90% TCCA chlorine tablets over calcium hypochlorite?
TCCA contains 90% available chlorine compared to 70% in calcium hypochlorite. It dissolves much slower and more uniformly, and contains built-in cyanuric acid stabilizer that prevents active chlorine from breaking down quickly under direct sunlight, making it ideal for open reservoirs and rural gravity feeds.
Why is sulfur dioxide required before discharging treated sewage into Iraqi rivers?
Chlorine used for disinfecting sewage effluent is highly toxic to fish and river ecology. Iraqi environmental regulations require removing all chlorine residual before water is returned to the Tigris or Euphrates rivers. Sulfur dioxide reacts instantly to neutralize chlorine into harmless chloride and sulfate salts.
What is the optimal raw water pH range for aluminum sulfate coagulation in Iraq?
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.
