The PFAS remediation mandate is the single most impactful driver for activated carbon demand growth. The US EPA’s designation of PFOA and PFOS as hazardous substances under CERCLA (Superfund) has triggered an estimated USD 3.2 billion in annual remediation spending, with activated carbon filtration as the primary treatment technology. Coal-based activated carbon accounts for approximately 55% of global supply, while coconut shell-based carbon (preferred for drinking water due to its higher microporosity and lower ash content) represents 30%, and wood-based carbon makes up the remaining 15%.
8. Water Treatment Disinfectants Market (SDIC, TCCA, Chlorine)
The disinfectants and biocides segment of the water treatment chemicals market is valued at approximately USD 8.01 billion in 2026. Within this segment, chlorinated isocyanurates—comprising primarily trichloroisocyanuric acid (TCCA) and sodium dichloroisocyanurate (SDIC)—represent a rapidly growing sub-category valued at USD 4.8 billion in 2026 according to Persistence Market Research, with projections reaching USD 7.0 billion by 2033.

SDIC and TCCA are favored over liquid chlorine in decentralized and developing-market applications due to their solid form, transportability, and stability. SDIC is particularly valued in emergency water treatment, rural drinking water programs, and aquaculture, while TCCA dominates swimming pool and small-scale municipal water treatment markets due to its high available chlorine content (90%) and controlled-release tablet format. China remains the world’s largest producer of both compounds, with production concentrated in Shandong and Hebei provinces.
9. Key Industry Trends 2026–2030
The water treatment chemicals industry is undergoing structural transformation driven by sustainability imperatives, digitalization, and shifting regulatory landscapes. The following trends are projected to shape market dynamics through 2030 and beyond.
Trend 1: Shift from Inorganic to Polymer-Based Coagulants
The global transition from traditional alum and ferric chloride to pre-hydrolyzed coagulants like PAC is accelerating. PAC offers 30–50% lower dosage requirements, reduced sludge generation, and superior performance in cold water conditions. By 2030, PAC is projected to account for over 45% of total coagulant consumption globally, up from approximately 38% in 2026.
Trend 2: PFAS Remediation as a Market Catalyst
The PFAS treatment market is expected to exceed USD 4.5 billion by 2030, with activated carbon adsorption representing the primary treatment technology. The US, EU, and Australia have implemented or proposed PFAS drinking water limits ranging from 4 to 70 ppt, creating sustained demand for high-performance GAC and specialty adsorbents. Additionally, COD removal chemicals are seeing increased adoption as industries target lower organic discharge loads.
Trend 3: Digital Water Treatment and Real-Time Dosing
The integration of IoT sensors, AI-driven dosing optimization, and digital twin technology is transforming chemical treatment from a manual, reactive process to a predictive, data-driven discipline. Ecolab’s 3D TRASAR platform and Kemira’s KemConnect system collectively monitor over 150,000 industrial water systems globally, reducing chemical consumption by 15–30% while improving treatment reliability.
Trend 4: Green and Bio-Based Chemical Alternatives
Bio-based flocculants derived from chitosan, tannin, and plant-derived polysaccharides are gaining traction in markets with stringent sustainability mandates. While currently representing less than 2% of total flocculant volume, bio-based alternatives are projected to grow at a CAGR exceeding 12% through 2030, particularly in Europe and North America.
Trend 5: Water Reuse and Zero Liquid Discharge (ZLD)
Industrial water reuse and ZLD systems require intensive chemical treatment programs, including advanced antiscalants, biocides, and cleaning chemicals for membrane systems. The global ZLD systems market is projected to reach USD 1.8 billion by 2030, with associated chemical consumption generating an estimated USD 600 million in incremental demand.
Trend 6: Supply Chain Regionalization
Geopolitical tensions and supply chain disruptions experienced during 2020–2024 have accelerated regionalization of chemical production. India, Vietnam, and Mexico are emerging as alternative manufacturing hubs for water treatment chemicals, reducing reliance on Chinese supply. India’s PAC production capacity is projected to double by 2028, supported by government Production Linked Incentive (PLI) schemes.
10. Regulatory Standards Comparison
Regulatory frameworks governing water treatment chemicals vary significantly across jurisdictions, impacting permissible chemical types, dosage limits, and residual concentrations. The table below compares key parameters across four major regulatory regimes.
| Parameter | WHO Guidelines | US EPA | EU (DWI/EU 2020/2184) | China (GB 5749-2022) |
|---|---|---|---|---|
| Turbidity (drinking water) | <1.0 NTU (ideally <0.1) | <0.3 NTU (95th percentile) | <1.0 NTU | <1.0 NTU (source: <3.0) |
| Residual Aluminum | 0.2 mg/L (health-based) | 0.05–0.2 mg/L (SMCL) | 0.2 mg/L | 0.2 mg/L |
| Residual Chlorine (free) | 0.2–5.0 mg/L | 4.0 mg/L (MRDL) | 0.1–0.3 mg/L (typical) | ≥0.05 mg/L (at tap) |
| Residual Acrylamide (from PAM) | 0.5 µg/L | Zero (treatment technique) | 0.10 µg/L | 0.50 µg/L |
| COD (industrial discharge) | Not specified | Permit-based (typically 50–125 mg/L) | 125 mg/L (general) | 50–100 mg/L (Class IA) |
| PFAS (PFOA + PFOS) | 0.1 µg/L (provisional) | 0.004 µg/L (MCL, 2024) | 0.10 µg/L (proposed 2024) | 0.04 µg/L (provincial pilot) |
| Trihalomethanes (THMs) | Not specified (carcinogenicity) | 0.080 mg/L | 0.100 mg/L | 0.060 mg/L |
| Approved Coagulants | Guideline-based | NSF/ANSI 60 certified | EN 12901/12902 compliant | GB/T 22627 (PAC standard) |
| PAM Approval for Drinking Water | Residual-based limit | NSF/ANSI 60 certified (dose-dependent) | Member state approval required | GB 17514 (drinking water grade) |
The EU’s revised Drinking Water Directive (2020/2184), fully effective since January 2023, introduced the most stringent acrylamide residual limit globally at 0.10 µg/L—five times tighter than WHO guidelines. This has driven European water utilities to adopt higher-purity PAM grades and optimize dosing precision. China’s GB 5749-2022, implemented in 2023, tightened 97 parameters compared to the 2006 version, including stricter limits on turbidity, disinfection byproducts, and heavy metals.

Methodology Notes
Where multiple sources provide differing estimates for the same metric, this report presents a range and identifies the source for each data point. Regional market sizes are calculated using a top-down allocation model based on regional share percentages reported by Fortune Business Insights, Mordor Intelligence, and Grand View Research, applied to the blended consensus global market value. Country-level figures within regions are allocated based on GDP-weighted industrial output and population-served-by-water-utilities ratios. All currency figures are expressed in US dollars unless otherwise noted. Market size figures represent manufacturer-level revenue unless explicitly stated as retail or end-user pricing.
