Core offering

LG Water Solutions manufactures and sells water treatment membrane products, including reverse osmosis (RO) membranes built on proprietary thin-film nanocomposite (TFN) technology, ultrafiltration/membrane bioreactor (UF/MBR) membranes, and ion exchange (IX) resins. The portfolio targets seawater and brackish water desalination, water reuse, industrial process water, and contaminant removal applications for municipal, industrial, and commercial customers worldwide.

Product overview

LG Water Solutions, a division of LG Chem, offers a comprehensive water treatment portfolio built around three core membrane technologies: NanoH2O™ RO membranes (with TFN technology for seawater and brackish water applications), QuantumFlux™ UF/MBR membranes (PVDF hollow-fiber membranes using TIPS process), and QuantumPure™ IX resins (ion exchange solutions including SAC, SBA, WAC, WBA, and Mixed Bed variants). These products are supported by software tools like Q+ Projection Software for system design and membrane modeling. The company specializes in serving municipal, industrial, and commercial sectors across applications including desalination, wastewater treatment/reuse, industrial water, ultrapure water, and PFAS removal.

Partnerships

Two partnerships are on record, tiered core and notable.

• Orange County Water DistrictcoreStrategic or Co-development PartnerLG Chem's BW 400 ES RO membrane was piloted at the Groundwater Replenishment System (GWRS), the world's largest indirect potable reuse facility, successfully completing over 10,000 hours of membrane piloting and evaluation. Following qualification, LG Chem was awarded opportunity to replace three trains totaling 57 MLD (15 MGD).
• Culligan Italiana S.p.A.notableTechnology or IntegrationCulligan Italiana designed and built the SWRO system on Elba Island, Italy, equipped with LG Water Solutions' industry-leading highest salt rejection SWRO membranes. The system delivers excellent permeate water quality at lower energy consumption.

Direct peers

• Lanxess (ion exchange resins): Lanxess Lewatit ion exchange resins compete directly with LG's QuantumPure IX portfolio across water treatment, condensation polishing, and industrial demineralization applications.
• Purolite (Ecolab): Purolite (now an Ecolab company) supplies premium IX resins that directly rival LG's QuantumPure in industrial, power, and PFAS removal applications.
• Toray Industries (Toray Membrane): Toray supplies RO, NF, UF and MBR membranes globally and is one of LG Water Solutions' most direct competitors in large-scale desalination RFPs, including Japan/Asia-Pacific and Middle East markets where both firms compete for the same mega-plant contracts.
• Hydranautics (Nitto Group): Hydranautics is a Nitto-owned RO/NF membrane manufacturer serving seawater desalination, industrial water and reuse — directly comparable in SWRO chemistry, boron rejection targets, and foul-resistant element design as LG's NanoH2O line.
• DuPont Water Solutions (FilmTec): DuPont's FilmTec membranes are the historical global #1 in RO/NF spiral-wound elements. Directly comparable to LG's NanoH2O product line, competing head-to-head in SWRO, BWRO, and ultrapure water applications for municipal and industrial customers.

Regional players

• Vontron Technology: Vontron is a leading China-based RO membrane producer competing primarily in domestic and Asia-Pacific municipal/industrial projects. Adjacent peer because it shares the SWRO/BWRO product category and targets similar end-uses, but with a regional go-to-market.

Broad incumbents

• SUEZ Water Technologies & Solutions: SUEZ (now part of Veolia in parts of the world) supplies a wide portfolio of membranes, IX resins, antiscalants and process services globally, overlapping with LG's full RO/UF/IX offering but at a broader, integrated-water-solutions level.
• Pentair (X-Flow): Pentair's X-Flow hollow-fiber UF/MBR membranes overlap with LG's QuantumFlux line, while its broader water treatment portfolio competes for the same industrial and municipal wallet.
• Veolia Water Technologies: Veolia operates large-scale desalination and reuse plants and supplies membrane elements plus EPC services. Competes with LG for project-level supply, particularly in Middle East and European municipal tenders.

Emerging players

• Kuraray (Membrana, water treatment): Kuraray supplies specialty membranes and is investing in next-gen chemistries; overlaps with LG's RO/NF portfolio in select Asian and European industrial water projects, representing a smaller but technically credible challenger.
