Key Players
Competitive Landscape
Plant operators approve a membrane chemical after a projection run and a field trial that tracks normalised flux, pressure drop and salt passage, and a change of antiscalant means a new trial on a working train. Ecolab's 4% price contribution in Q2 2026 shows customers on service contracts accepting surcharges.[2]
Water treatment groups compete on field service and monitoring, specialist formulators such as BWA Water Additives and Genesys International compete on antiscalant chemistry, and distributors such as Lenntech compete on reach to small plants. Membrane-safe biocides overlap with general water treatment. A 3.4% CAGR is forecast for the biocides market, about half the 6.1% pace of the membrane chemicals market, so non-oxidising membrane grades will gain weight inside biocide portfolios.

Concession holders in Fortaleza and planners at Anglian Water are writing chemical supply into long-term operating plans, so early qualification at these plants will decide supplier positions for years.
Who leads the membrane chemicals market?
Ecolab, Kemira and Veolia carry the broadest documented water treatment results among the profiled companies, and Ecolab's Global Water fixed currency sales reached USD 2,215.5 million in Q2 2026.[2] Kemira and Veolia report water results by quarter and by half year.[1][7]
Which companies have documented positions?
Ecolab reports Global Water and Global High-Tech growth every quarter.[2] Kemira reports Water Solutions trends and acquisitions, and Veolia reports Water Technologies revenue by half year.[1][7]
What should buyers evaluate before approving a supplier?
Buyers check compatibility with the membrane warranty, run projection software and field trials for scaling and fouling, then confirm drinking water approval for potable plants. Laboratory autopsy support, field service visits and secure supply in a phosphonate shortage complete the approval checklist.
How is competition expected to change through 2036?
Monitored dosing contracts at desalination and reuse plants will take share from drum sales of generic antiscalant. Deals such as the Kemira purchase of the Clear Water Technologies business point to fewer, larger suppliers with regional service teams.[1]
