FAQS on sodium thiosulfate in water treatment
Q: What is the primary use of sodium thiosulfate in water treatment?
A: Sodium thiosulfate is primarily used to neutralize residual chlorine in water. It reacts with chlorine to form harmless chloride and sulfate ions. This makes it essential for dechlorinating treated wastewater or drinking water.
Q: How does sodium thiosulfate work in dechlorinating water?
A: Sodium thiosulfate chemically reduces chlorine (Cl₂) or hypochlorite (OCl⁻) through a redox reaction. The reaction converts chlorine into non-toxic chloride (Cl⁻) and sulfate (SO₄²⁻) ions. This ensures safe water discharge or testing.
Q: Is sodium thiosulfate safe for use in drinking water treatment?
A: Yes, sodium thiosulfate is recognized as safe for dechlorinating drinking water in controlled doses. It rapidly breaks down chlorine without introducing harmful byproducts. Regulatory agencies approve its use within specified concentration limits.
Q: What are the advantages of using sodium thiosulfate over other dechlorination agents?
A: Sodium thiosulfate is cost-effective, easy to handle, and reacts quickly with chlorine. Unlike sulfur-based alternatives, it produces no foul odors or hazardous residues. Its stability in solution also simplifies storage and dosing.
Q: Can sodium thiosulfate be used in wastewater treatment for industrial applications?
A: Yes, sodium thiosulfate is widely used in industrial wastewater treatment to remove excess chlorine. It protects aquatic life by eliminating toxic chlorine before discharge. Its effectiveness and low environmental impact make it a preferred choice.
