Water treatment covers potable (purification, USP/EP purified water, EW-1/2 ultrapure), wastewater (municipal, industrial, oily), seawater desalination (RO, MED) and water reuse. Veolia, Suez, Xylem (US), Grundfos (DK, circulation pumps), KSB and Pentair are European industry giants. Membrane technology DOW, Toray, LG and Hydranautics lead.

FAQ
Q RO vs nanofiltration?
A
RO (pore size 0.0001 μm): 99% ion rejection — seawater desalination, purified, ultrapure. NF (0.001 μm): 90% rejection of divalent ions (Ca2+, Mg2+) — softening and tertiary drinking-water treatment.
Q MBR vs conventional activated sludge?
A
MBR: membrane separation + biology, effluent suspended solids 0, reusable, 1/3 footprint. Higher opex (membrane replacement 5-8 years). New industrial parks and water-reuse projects prefer MBR.
Q Ultrapure water EW-1?
A
Semiconductor (resistivity 18.2 MΩ·cm @ 25°C, TOC < 5 ppb). Veolia Sidem, Ovivo and Pure Water lead. Multi-stage RO + EDI + UV + polishing resin is typical.
