The water and wastewater treatment concentrates industry encompasses the sectors and chemicals employed to purify, disinfect, and manage liquid effluents at industrial, municipal, and agricultural scales. This includes coagulants (e.g., alum, ferric chloride), disinfectants (chlorine, ozone), pH adjusters, antiscalants, flocculants, sludge conditioners, and advanced specialty concentrates such as PFAS-binding resins. These chemical products are supplied by major chemical providers, often as bespoke formulations tailored to specific treatment systems.
Several driving factors fuel the growth of this sector. Intensifying urbanisation has driven sewage production—India generates approximately 38,354 MLD (million-litres/day) of municipal sewage, whereas its treatment capacity is only 11,786 MLD, indicating a vast infrastructure and treatment gap.
Regulatory measures such as India’s National Water Policy (2012), National Environment Policy (2006), National Sanitation Policy (2008), and National River Conservation Plan have mandated stricter control, reuse, and treatment of wastewater, promoting concentrate management through centralized plants and decentralized systems. Governmental programmes such as the Jal Jeevan Mission, National Mission for Clean Ganga, and Atal Mission for Rejuvenation and Urban Transformation (AMRUT), along with the establishment of the Jal Shakti Ministry in 2019, have additionally funded efforts to upgrade treatment infrastructure.
Chemical concentrates are critical to meeting tightening discharge standards for nutrients, pathogens, heavy metals, and emerging contaminants such as PFAS. A recent US landmark study identified that 95% of sewage sludge sites and associated wastewater plants exhibited elevated levels of PFAS downstream—often exceeding draft EPA guidance of as low as 0.0009 parts per trillion for PFOA—underscoring the urgency to enhance treatment practices through more effective chemical dosing.
Regulatory pressure and government initiatives have been primary drivers. In the United States, the EPA’s Effluent Limitation Guidelines regulate approximately 40,000 direct-discharge industrial facilities and 129,000 point-source dischargers, mandating the use of best available treatment technologies to comply with the Clean Water Act.
Additionally, federal funding mechanisms such as the US Congress-sponsored infrastructure programs under the Clean Water State Revolving Fund have allocated billions for upgrading plants and chemical systems. In Brazil, PRODES reimburses up to 50 % of capital for new wastewater plants if performance standards are met

Emerging Trends
Adoption of Advanced Water Reuse Technologies
A significant trend in the water and wastewater treatment market is the increasing adoption of advanced water reuse technologies. This shift is driven by the need to address water scarcity and improve water sustainability.
For instance, in 2024, the U.S. Environmental Protection Agency (EPA) launched the National Water Reuse Action Plan, aiming to enhance water reuse across the country. The plan outlines 37 actions across 11 strategic themes to promote the adoption of water reuse as part of integrated water resources planning.
Additionally, the EPA awarded $6.4 million in research grants to Iowa State University and the Water Research Foundation to support national efforts in reducing technological and institutional barriers for expanded water reuse. These initiatives are part of a broader effort to unlock the nationwide potential of water reuse and ensure a sustainable water future .
Globally, countries are implementing similar strategies. For example, China has mandated raising the proportion of sewage that must be treated to reuse standards to 25% by 2025, as part of its 14th Five-Year Plan . These developments indicate a global shift towards recognizing water reuse as a critical component of sustainable water management.
