Water treatment is essential for ensuring the safety and efficiency of industrial processes, power generation, manufacturing, and municipal water supplies. However, raw water sources often contain dissolved minerals, contaminants, and aggressive vapours that can cause corrosion, scaling, and fouling in industrial systems.
At Bonchem, we provide industry-leading water purification chemicals designed to control deposit buildup, corrosion, and fouling, ensuring that industrial equipment operates at peak efficiency. Our custom-built dosing systems and proven chemical treatment programs help industries maintain high water quality standards and protect their systems from long-term damage.
This article explores how water treatment removes chemicals, the role of water purification chemicals, and the most effective chemical treatment methods used in industrial water systems.
How Water Treatment Removes Chemicals
Water treatment involves several chemical and physical processes to remove contaminants, neutralise harmful substances, and improve water quality for industrial use. The process typically includes the following steps:
Coagulation and Flocculation
Purpose: Removes suspended particles and heavy metals.
How It Works: Water purification chemicals like coagulants are added to water, causing tiny particles to clump together into larger masses (flocs).
Common Chemicals Used:
- Aluminium sulphate (Alum)
- Ferric chloride
- Polyacrylamides
Sedimentation and Solid/Liquid Separation
Purpose: Allows flocs to settle at the bottom for easy removal.
How It Works: Once coagulated particles form larger clumps, they sink due to gravity. Clarifiers and sedimentation tanks help separate these solids.
Bonchem’s Role: Our solid/liquid separation treatment programme ensures efficient sludge removal without affecting water quality.
Filtration
Purpose: Removes remaining solids, bacteria, and chemical residues.
How It Works: Water passes through sand, gravel, or activated carbon layers to remove impurities. Membrane filtration (e.g., reverse osmosis) is used for finer purification.
Common Chemicals Used:
- Activated carbon (removes organic compounds and chlorine)
- Iron removal agents
pH Adjustment and Neutralisation
Purpose: Controls water acidity or alkalinity to prevent corrosion and scaling.
How It Works: Acid or base chemicals are added to balance water pH.
Common Chemicals Used:
- Sodium hydroxide (raises pH, reduces acidity)
- Sulphuric acid (lowers pH, reduces alkalinity)
Disinfection and Chemical Oxidation
Purpose: Kills bacteria, viruses, and organic contaminants.
How It Works: Oxidising agents break down contaminants, ensuring water safety.
Common Chemicals Used:
- Chlorine (widely used for microbial disinfection)
- Ozone (powerful oxidant for organic pollutants)
Hydrogen peroxide
Scale and Corrosion Inhibition
Purpose: Prevents mineral deposits, corrosion, and fouling in pipes and heat exchangers.
How It Works: Water purification chemicals inhibit scaling and protect metal surfaces from degradation.
Common Chemicals Used:
- Phosphates and polyphosphates (prevent scaling)
- Corrosion inhibitors (protect metal surfaces)
- Chelating agents (bind with unwanted minerals)
Chemical Dosing and Continuous Monitoring
Purpose: Ensures water quality remains consistent and compliant.
How It Works: Dosing pumps and automated monitoring systems regulate the flow of water purification chemicals to optimise treatment.
Bonchem’s Role: We provide and maintain custom-built dosing systems for precise chemical delivery and cost-effective results.

FAQs About Water Purification Chemicals
What are water purification chemicals used for?
Water purification chemicals remove contaminants, control pH levels, disinfect water, prevent scaling, and reduce corrosion in industrial and municipal water systems.
How do coagulation and flocculation improve water quality?
These processes help remove suspended particles and heavy metals by allowing them to clump together into larger particles that can be easily filtered or removed.
What is the most effective chemical for water disinfection?
Chlorine is the most widely used chemical disinfectant, but ozone and hydrogen peroxide are also effective for killing bacteria and viruses.
How does Bonchem help industries with water treatment?
Bonchem provides high-performance water purification chemicals, custom-built dosing systems, and expert service engineers to ensure cost-effective and reliable water treatment.
Can water purification chemicals prevent corrosion in industrial systems?
Yes! Corrosion inhibitors and pH regulators help protect pipes, tanks, and heat exchangers from rust and damage caused by aggressive water conditions.
What are the environmental impacts of water purification chemicals?
Proper dosing and responsible disposal minimise environmental impact. Bonchem ensures all chemicals are applied safely and in compliance with environmental regulations.
How often should water quality be monitored in industrial applications?
Water quality should be monitored continuously using automated systems or checked regularly to maintain compliance and efficiency.
What type of filtration is used in industrial water treatment?
Depending on their water quality needs, industries use sand filtration, activated carbon filters, and membrane filtration (reverse osmosis).
