Effective water and wastewater treatment depends on the right chemistry at every process stage â from raw water clarification and effluent coagulation to sludge dewatering and water recycling. At ZEXCORP, we supply a complete range of industrial-grade water treatment chemicals, backed by application engineering support, dosing optimization, and on-site technical assistance across India.
Whether you operate an ETP, STP, WTP, CETP, or a ZLD system, our chemical programs are designed to help you achieve consistent CPCB and State PCB discharge compliance, reduce operating costs, and maximize water recovery.
Our Chemical Product Range
Coagulants
Inorganic and organic coagulants for rapid destabilization of colloidal particles and suspended solids. Effective across potable water, industrial water, and wastewater applications. Includes poly-aluminium chloride (PAC), aluminium sulphate, ferric chloride, and organic coagulant alternatives.
Flocculants & Polyelectrolytes
High-performance anionic, cationic, and amphoteric polyelectrolytes (polymers) for enhanced flocculation and solid-liquid separation. Available in powder, emulsion, and liquid forms â tailored to your specific effluent characteristics, flow rates, and equipment.
Sludge Dewatering Polymers
Specially formulated polymers that improve dewatering performance across belt presses, filter presses, centrifuges, and screw presses. Achieve higher cake dryness, lower sludge volumes, reduced disposal costs, and better filtrate clarity.
Sludge Thickening Agents
Polymers and conditioning chemicals that enhance gravity thickening, dissolved air flotation (DAF), and mechanical thickening processes. Reduce downstream equipment load and energy consumption.
Bacteria Cultures & Bioaugmentation
Specialized microbial cultures for ETP and STP biological treatment. Accelerate plant startup, recover from toxic shock loads, enhance COD/BOD degradation, and maintain stable biological performance in MBBR, ASP, and SBR systems.
Specialty Chemicals
Antiscalants for RO membrane protection, biocides for cooling towers, activated carbon for adsorption, pH correction chemicals, defoamers, and odour control agents. Complete chemical programs for every treatment stage.

Frequently Asked Questions
What is the difference between a coagulant and a flocculant?
Coagulants neutralize the electrical charges on suspended particles, causing them to destabilize and begin aggregating. Flocculants (typically polyelectrolytes/polymers) then bridge these micro-flocs into larger, heavier flocs that settle faster. In most ETP and WTP systems, both coagulation and flocculation are used in sequence for effective solid-liquid separation.
How do I choose the right polyelectrolyte for sludge dewatering?
The choice depends on your sludge type (biological, chemical, or mixed), the dewatering equipment (belt press, filter press, centrifuge, or screw press), and the target cake dryness. Cationic polyelectrolytes are most common for biological sludge, while anionic polymers are used for mineral or inorganic sludges. We conduct polymer screening trials with your actual sludge to identify the best product and optimal dosage.
Can you supply chemicals for both ETP and drinking water plants?
Yes. We supply chemicals for the entire water cycle â industrial ETP/STP/CETP, potable water treatment plants (WTP), RO systems, ZLD plants, cooling towers, and boilers. Our potable water grade coagulants and flocculants meet NSF, WHO, and IS standards for safe drinking water treatment.
Do you provide on-site technical support?
Absolutely. Our application engineers provide on-site jar testing, dosing optimization, operator training, and regular plant visits. We also offer remote monitoring and troubleshooting support for plants equipped with our NEXUS IoT platform.
