Key Water Treatment Chemical Categories

Coagulants & Flocculants

Aluminum Sulfate (Alum)

A widely used inorganic coagulant for drinking water and wastewater treatment. Aluminum sulfate promotes particle destabilization and effective clarification and sludge removal in municipal and industrial water treatment systems.

Polyaluminum Chloride (PAC)

A high-efficiency pre-polymerized aluminum coagulant delivering rapid floc formation and reduced sludge generation compared to traditional alum. PAC is widely used in municipal and industrial wastewater and high-turbidity applications.

Ferric Chloride (FeCl₃)

A strong inorganic coagulant used for wastewater treatment, phosphorus removal, and odor control. Ferric chloride performs well across a wide pH range and is particularly effective in industrial effluents with high organic loads.

Ferric Sulfate (Fe₂(SO₄)₃)

An iron-based coagulant used in drinking water and wastewater treatment for turbidity, color, and phosphorus removal. Ferric sulfate offers stable performance and reduced corrosion compared to chloride-based salts.

Ferrous Sulfate (FeSO₄)

Primarily used in wastewater treatment and industrial effluent applications, ferrous sulfate supports coagulation and reduction processes. It is commonly applied where iron dosing and cost-effective treatment solutions are required.

Polymer Flocculants

Synthetic polymer flocculants used alongside inorganic coagulants to enhance floc size, settling rate, and solid-liquid separation efficiency. Available in anionic, cationic, and non-ionic forms to suit different water characteristics.

pH Control & Neutralization Chemicals

Sodium Hydroxide

A strong alkaline chemical, known as Caustic Soda, used to raise pH, neutralize acidic streams, and control alkalinity in municipal and industrial water treatment processes with precise dosing and rapid reaction control.

Calcium Hydroxide

A cost-effective alkaline reagent, known as Hydrated Lime, applied for pH adjustment, softening, and neutralization of acidic wastewater, commonly used in large-scale municipal treatment systems and industrial effluent applications.

Calcium Oxide (CaO)

A highly reactive alkaline material, known as Quicklime, used for rapid pH correction, sludge conditioning, and neutralization in wastewater treatment, offering fast reaction rates and effective alkalinity generation for industrial systems.

Sulfuric Acid (H₂SO₄)

A strong mineral acid used to lower pH, control alkalinity, and neutralize alkaline water streams in industrial and municipal treatment processes requiring precise, controlled acid dosing and handling under regulated operating conditions.

Hydrochloric Acid (HCl)

An effective acid for pH reduction and scale control, widely applied in water and wastewater treatment systems due to rapid neutralization performance and ease of handling during routine plant operations and maintenance activities.

Carbon Dioxide (CO₂)

A mild acidifying agent used for controlled pH reduction in drinking water treatment, providing gentle neutralization, improved safety, and reduced corrosion compared to strong mineral acids in modern treatment systems.

Disinfectants & Oxidizing Agents

Chlorine Gas (Cl₂)

A widely used disinfectant for drinking water and wastewater treatment, providing rapid pathogen inactivation and residual protection, commonly applied in municipal systems requiring reliable disinfection under standards.

Sodium Hypochlorite

A liquid chlorine-based disinfectant used for water and wastewater treatment, offering effective microbial control, easier handling than chlorine gas, and flexible dosing for municipal and industrial treatment systems operations.

Chlorine Dioxide (ClO₂)

A highly reactive alkaline material, known as Quicklime, used for rapid pH correction, sludge conditioning, and neutralization in wastewater treatment, offering fast reaction rates and effective alkalinity generation for industrial systems.

Hydrogen Peroxide

A strong oxidizing agent used for disinfection and advanced oxidation processes, decomposing into water and oxygen while supporting environmentally friendly removal of organic contaminants in water treatment systems.

Ozone (Trioxygen)

A powerful on-site generated oxidizing disinfectant providing rapid microorganism inactivation, improved taste and odor control, and effective oxidation without leaving residual chemical byproducts in treated water systems applications.

Potassium Permanganate

An inorganic oxidizing agent used for iron, manganese, and sulfide removal, taste and odor control, and pre-oxidation to improve downstream filtration performance in water treatment plants and systems operations and reliability control.

Specialty & Process Chemicals

Corrosion Inhibitors

Specialty chemicals used to protect pipelines, equipment, and treatment systems from corrosion, extending asset life and reducing maintenance requirements, improving reliability in municipal and industrial water treatment facilities.

Scale Control Inhibitors

Chemical additives designed to prevent scale formation on membranes, heat exchangers, and pipelines, maintaining efficiency, reducing downtime, and supporting operation of water and wastewater treatment systems.

Antifoaming Agents

Process chemicals applied to control foam generation in treatment tanks and reactors, improving process stability, preventing overflow risks, and supporting efficient gas-liquid separation during water and wastewater treatment.

Dechlorination Agents

Specialty chemicals used to remove residual chlorine or chloramines from treated water, protecting downstream processes, aquatic environments, and sensitive equipment in municipal and industrial water treatment systems.

Chelating Process Agents

Process chemicals used to bind dissolved metals, improve contaminant removal efficiency, and enhance treatment performance by stabilizing metal ions during water and wastewater purification processes operations systems.

Biocides Chemicals

Specialty chemicals applied to control biological growth, biofouling, and microbial contamination in water systems, supporting hygienic operation, asset protection, and consistent treatment performance in industrial applications.
