Water Treatment Chemicals and Their Applications in 2025

As global water scarcity intensifies, environmental regulations tighten, and industrial users aim for more sustainable operations, Water Treatment Chemicals are playing a more critical role than ever in 2025. Whether it’s municipal water purification, cooling system stabilization, reverse osmosis membrane protection, or industrial wastewater reuse, the right chemical solutions can significantly reduce operating costs, extend equipment life, and ensure compliance.

 

Water Treatment Chemicals and Their Applications


Today’s users are not only asking whether a chemical is effective—they want to know if it’s safe, environmentally responsible, and compatible with their on-site systems. TJCY addresses this growing demand with a wide portfolio of Water Treatment Chemicals, backed by technical expertise and flexible supply capabilities. Our goal is to support your entire water treatment process—from dosing to discharge—with efficient, proven solutions.

 

Coagulation and Flocculation: For Clarity and Efficient Settling

 

The first stage in many water treatment processes involves removing suspended solids. Coagulants and flocculants work together to aggregate particles and settle them out, making the water clearer and easier to process downstream.

 

Product Name

CAS No.

Application Overview

Polyaluminum Chloride (PAC)

1327-41-9

Highly effective in removing turbidity and improving sedimentation; ideal for surface water and primary treatment.

Polyacrylamide (PAM)

9003-05-8

Enhances floc structure after coagulant dosing; improves sludge thickening and dewatering.

 

Recommended for drinking water pre-treatment, tailings water from mining, pulp & paper, and industrial sedimentation processes.

 

Scale and Corrosion Control: For Long-Term System Reliability

 

Water rich in calcium, magnesium, or iron can cause scaling and corrosion, damaging pipelines and reducing system efficiency. Proper chemical treatment helps protect assets and lower maintenance costs.

 

Product Name

CAS No.

Application Overview

Sodium Hexametaphosphate

10124-56-8

Prevents calcium scaling and disperses solids; widely used in cooling and boiler water systems.

Sodium Gluconate

527-07-1

Bio-based, eco-friendly corrosion inhibitor; ideal for phosphate-free formulations.

EDTA Disodium Salt

139-33-3

Effective chelating agent for iron and manganese; reduces corrosion and prevents metal fouling.

 

Use in combination with water analysis (TDS, conductivity, hardness) and automated dosing systems for best results.

 

Disinfection and Microbial Control: For Safe, Biofilm-Free Systems

 

Uncontrolled microbial growth leads to odor, corrosion, and energy losses. Our oxidizing and non-oxidizing biocides offer broad-spectrum control for both open-loop and closed-loop systems.

 

Product Name

CAS No.

Application Overview

Sodium Hypochlorite

7681-52-9

Powerful oxidizing disinfectant, widely used in municipal water and industrial cooling towers.

Hydrogen Peroxide

7722-84-1

Leaves no harmful byproducts, suitable for sensitive disinfection scenarios like food & beverage.

Trichloroisocyanuric Acid (TCCA)

87-90-1

Slow-release chlorine tablet; ideal for long-term sterilization in tanks, reservoirs, and pools.

 

For systems with foaming concerns, pair with low-residue defoamers for complete treatment.

 

pH Adjustment and Cleaning: For System Balance and Membrane Protection

 

Maintaining proper pH is essential for reaction efficiency, microbial control, and RO system longevity. Regular pH adjustment and chemical cleaning prevent scale and acid/alkaline imbalance.

 

Product Name

CAS No.

Application Overview

Citric Acid

77-92-9

Natural, biodegradable acidifier; suitable for pH control in food-grade and low-hardness systems.

Sulfamic Acid

5329-14-6

Ideal for RO and heat exchanger cleaning; low vapor pressure and strong descaling power.


Delivering the Quality Service You’re Looking For

 

Solutions That Fit Your System

We don’t just sell chemicals—we help you build full dosing programs based on actual water quality data. For example, with high-TDS groundwater, we recommend combining PAC, PAM, and a low-phosphorus antiscalant to protect RO membranes while improving settling performance.

 

Support for Compliance and Sustainability

Our oxidants, chelants, and pH regulators meet REACH and RoHS standards. Perfect for applications with strict discharge limits such as food & beverage, fine chemicals, or zero-liquid discharge (ZLD) systems. Full SDS, COA, and third-party testing available.

 

Fast and Flexible Fulfillment

We offer multiple packaging sizes—from small bag reagents to ton barrels,delivery within 72 hours at the fastest. Our technical team supports remote dosing guidance, product selection, and on-site training when needed.
