Hydrochloric Acid
This is commonly used as a pH adjuster and descaling agent in the water treatment industry.
Hydrochloric acid, or HCl, effectively lowers the pH of alkaline water, making it more suitable for industrial processes. When water becomes too alkaline, it can cause corrosion or reduce treatment efficiency.
HCl helps balance the pH, ensuring proper system operation.
Additionally, hydrochloric acid dissolves limescale and mineral deposits that form in boilers, heat exchangers, and pipes. When breaking down these deposits, it maintains smooth water flow, prevents blockages, and improves system efficiency. Its powerful properties make hydrochloric acid essential for maintaining clean, efficient, and well-functioning water treatment systems in various industries.

Hydrogen Peroxide
Being a powerful oxidising agent, hydrogen peroxide plays an important role in water treatment by effectively disinfecting water. It breaks down harmful contaminants like bacteria, viruses, and organic matter, ensuring water safety and purity.
As hydrogen peroxide works, it decomposes into water and oxygen, leaving no harmful residues behind.
This makes it an eco-friendly alternative to chlorine and other chemical disinfectants. Water treatment facilities use it to control odours, remove pollutants, and improve water quality without adding toxic by-products.
Its versatility and environmental safety make hydrogen peroxide an excellent choice for maintaining clean water in both drinking water systems and wastewater treatment processes.

Phosphoric Acid
The main reason this chemical is in use is that it is a good corrosion inhibitor in the water treatment industry.
Phosphoric acid protects metal pipes and tanks by creating a layer of phosphate salts that prevents rust and corrosion. This protective layer shields infrastructure, especially in systems where water contains corrosive elements.
Since the latter reduces the risk of corrosion, phosphoric acid extends the lifespan of pipes, boilers, and storage tanks. It also helps maintain water flow efficiency by preventing blockages caused by rust build-up. This is what makes it valuable for industries that rely on metal infrastructure. Also, phosphoric acid ensures that systems remain durable, reliable, and safe for long-term use.
