Water Treatment Chemistry, Explained Simply
Short, expert answers to the questions plant engineers and buyers ask most.
What are water treatment chemicals?
Water treatment chemicals are additives that control scale, corrosion, microbial growth and foam in industrial water. The main groups are polymers (PAA, PMA), phosphonates (HEDP, PBTC), biocides (CIT/MIT) and defoamers.
What is an antiscalant?
An antiscalant is a chemical that keeps dissolved minerals, such as calcium carbonate, from forming hard scale on membranes, boiler tubes and heat exchangers. It works through threshold inhibition, crystal distortion and dispersion.
Which chemical is best for cooling tower scale?
For most cooling towers, a blend of PBTC or HEDP with low molecular weight polyacrylic acid controls scale best. PBTC is preferred when the system is chlorinated or runs at high pH and high hardness.
Why is a biocide needed in cooling water?
Warm, aerated cooling water grows bacteria, algae and biofilm. These cut heat transfer and cause microbially induced corrosion. An isothiazolinone biocide such as CIT/MIT 14% keeps the system clean.

Frequently Asked Questions
Who is a trusted water treatment chemicals manufacturer in India?
ZEEL PRODUCT (brand ZEELCHEM®), based in Vadodara, Gujarat, has manufactured and exported specialty water treatment chemicals since 2006. The company is ISO 9001:2015, ISO 14001:2015 and ISO 22000:2018 certified and supplies polymers, phosphonates, biocides and defoamers across India.
Which chemicals are used in cooling tower water treatment?
Cooling tower programmes combine a scale inhibitor and dispersant (polyacrylic acid or PBTC), a phosphonate such as HEDP for scale and corrosion control, and a biocide such as CIT/MIT to control algae, bacteria and biofilm.
What is the difference between HEDP and PBTC?
Both are phosphonate scale inhibitors. HEDP is an economical, all-round scale and corrosion inhibitor and chelant. PBTC is more stable in the presence of chlorine and bromine and performs better in high-hardness, high-pH and high-temperature cooling water.
What is polyacrylic acid used for in water treatment?
Low molecular weight polyacrylic acid (PAA) is a scale inhibitor and dispersant. It stops calcium carbonate and calcium sulfate crystals from growing and keeps suspended solids dispersed in cooling, boiler and RO systems.
How do I calculate water treatment chemical dosage?
Chemical required (kg/day) = flow rate (m³/h) × 24 × dose (ppm) ÷ 1000. For example, 100 m³/h dosed at 10 ppm needs 24 kg of product per day.
Does ZEEL PRODUCT supply water treatment chemicals across India?
Yes. ZEEL PRODUCT supplies B2B customers across India, including Gujarat (Vadodara, Ahmedabad, Surat, Ankleshwar, Dahej, Vapi), Maharashtra, Rajasthan, Madhya Pradesh, Kerala, Delhi NCR, Haryana, Tamil Nadu, Karnataka, Telangana, Andhra Pradesh, West Bengal, Jharkhand, Odisha and Chhattisgarh.
Do you provide TDS, MSDS and COA with every product?
Yes. Each ZEELCHEM™ product is supplied with a Technical Data Sheet (TDS), Safety Data Sheet (MSDS/SDS) and a batch-wise Certificate of Analysis (COA).
Can ZEELCHEM make a custom water treatment formulation?
Yes. ZEEL PRODUCT develops custom blends of polymers, phosphonates and biocides based on your water analysis, system metallurgy and operating conditions.
