Water treatment chemicals: Production
Why coagulants are local but polymers are global
What this tab covers Who makes it and how much: world capacity and output, utilisation, the top producing countries and companies globally and in India, concentration, new capacity coming, and each region's position.| Measure | Figure | Detail | Source |
|---|---|---|---|
| World capacity | not published for the family | no public capacity database; company disclosures are partial | |
| World output | about $41.46 billion of sales (2025) | IMARC 2025 | |
| Capacity utilisation | not published | Kemira reported lower volumes in 2025 from industrial customers and seasonal softness in water treatment, but expects growth in water treatment in 2026. | Kemira financial statements bulletin 2025 |
| Concentration | company shares not published; regional demand: Asia-Pacific 39.9%, top-3 regions 82.9% (IMARC 2025) | The service end (Ecolab, Veolia, Kurita, Solenis) and polyacrylamide (SNF) are concentrated; local coagulant supply is fragmented. Shares by country are given only as regional shares. | IMARC 2025; MarketsandMarkets 2025 |
| New capacity | not published for the family | Kemira: coagulant capacity additions in the UK, Spain and Norway and an activated carbon reactivation plant in Sweden; acquisitions of Water Engineering Inc. (completed Oct 2025) and AquaBlue (announced early 2026) to move into industrial water services. | Kemira AGM 2025; ChemXplore on Kemira 2025 results |

Largest producers: India
| Company | Country | Volume | Year | Source |
|---|---|---|---|---|
| Ion Exchange (India) segment split not given in source; order book Rs 9,011 crore | India | 734 Rs crore quarterly revenue (all segments: engineering, chemicals, consumer) | Q2 FY2026 | AlphaStreet, Ion Exchange Q2 FY26 results |
| Thermax (chemicals business) makes ion-exchange resins and water treatment chemicals (indicative) | India | not published | n/a | not verified in sources reached |
| Gujarat Alkalies and Chemicals chlor-alkali producer that also makes poly-aluminium chloride (indicative) | India | not published | n/a | indicative |
India makes its own alum, PAC, ferric salts and hypochlorite near chlor-alkali sites, but imports much polyacrylamide and specialty biocides. Ion Exchange and Thermax are the main listed Indian treatment companies; global service firms also operate in India. Asia-Pacific, including India, is the fastest-growing region at 5.8% a year (MarketsandMarkets).
Position by region
| Region | Position |
|---|---|
| US | 24.6% of world demand with North America (IMARC 2025). The 2024 EPA PFAS drinking water limits favour activated carbon and ion exchange over coagulants. |
| EU | 18.4% of demand (IMARC 2025). Strict phosphorus limits under the revised Urban Wastewater Treatment Directive support ferric and aluminium coagulant use; Biocidal Products Regulation limits the range of biocides. |
| India | Fast-growing demand from municipal water programmes, industrial effluent rules and zero liquid discharge in textiles and pharma. Domestic coagulant supply; imported polymers. |
| China | Large domestic producer of polyacrylamide, phosphonates and PAC, and an exporter of all three (indicative). |
| Japan | Home of Kurita; mature demand led by electronics ultra-pure water. |
| Middle East | Desalination drives antiscalant, coagulant and membrane cleaner demand; part of the 7.9% Middle East and Africa share (IMARC 2025). |
