De.Mem

What De.Mem does

De.mem Limited (ASX: DEM) is a Singapore-headquartered, Australian-listed decentralised water and wastewater treatment company that designs, builds, owns, operates, and services membrane-based treatment systems for industrial, municipal, and residential customers. Its core technology platform comprises proprietary hollow fibre membranes — Ultrafiltration (UF), Nanofiltration (NF), Reverse Osmosis (RO), and Forward Osmosis (FO) — originally developed under exclusive worldwide license from Nanyang Technological University (NTU) Singapore's Membrane Technology Centre, and manufactured at its Singapore facility as 4-inch and 8-inch modules or complete turn-key systems. The company also produces a graphene-oxide-enhanced polymer membrane (NSF/ANSI 61 certified in 2024) and operates the proprietary de.live PLC-based SCADA and remote-monitoring platform with predictive-maintenance analytics.

The commercial model is a "One Stop Shop" combining capital equipment supply, long-term Build-Own-Operate (BOO) and Operations & Maintenance (O&M) service contracts, and specialty chemicals and consumables supplied under those contracts. Pricing is quote-based across multi-year recurring service agreements and project-based capital sales ranging from roughly A$200K to A$2.8M. De.mem serves gold mining, food & beverage (notably Givaudan in Singapore across four BOO contracts since 2017), oil & gas / electronics / heavy industry, municipal and infrastructure, and a nascent consumer point-of-use residential filter line, with customers concentrated in Australia, Singapore, and Germany and additional project execution in Vietnam, Cambodia, PNG, Fiji, and the Netherlands.

Founded 2014 and ASX-listed since April 2017 (implied A$19M IPO market capitalisation), De.mem has grown to approximately 75 employees and eight bolt-on acquisitions through 2025, integrating water-treatment OEMs (Akwa-Worx, Pumptech, Stevco, Auswater, Border Pumpworks, Geutec), and specialty chemicals suppliers (Capic 2021, Core Chemicals 2025). The company reports 27 successive quarters of growth as of December 2025 and is targeting record profits in 2026.

Revenue model

1. Equipment Design, Build and Sale: Design, manufacture and supply of water and wastewater treatment systems including membrane-based plants, containerised solutions, packaged systems, and individual equipment. Revenue from capital equipment sales to industrial clients. Systems include Membrane Bioreactors (MBRs), Ultrafiltration, Reverse Osmosis, and other treatment technologies.
2. Build, Own, Operate (BOO) and Operations & Maintenance (O&M) Services: Long-term service contracts where De.mem operates and maintains client water treatment facilities. Provides qualified operators, technicians, process engineers, and supplies all chemicals and consumables. Generates recurring revenue streams with multi-year contract terms. Signed multiple BOO contracts with multinational corporations including Givaudan and food & beverage clients.
3. Chemicals and Consumables Supply: Supply of specialty chemicals, reagents, and consumables required for ongoing operations of water treatment facilities. Cross-sold to existing customer base following acquisitions (Core Chemicals specialty chemicals, Capic chemicals business, De.mem-Capic chemicals).
4. Acquisition Synergies and Cross-Selling: Revenue synergies from cross-selling acquired companies' products through expanded distribution network. Example: specialty chemicals from Core Chemicals cross-sold to De.mem's 15 gold mining customers; De.mem membrane technology supplied to Auswater's existing customer base.
5. Technology Licensing (Aromatec): Sub-licensed FO technology rights for beverage production applications to Aromatec (32% De.mem stake). Aromatec pursues large commercial market in beverage concentration (milk powder, coffee, tea, beer, fruit juice) using De.mem-Aromatec FO technology.

Core offering

De.mem designs, manufactures, and operates decentralised water and wastewater treatment systems based on proprietary hollow fibre membrane technology (UF, NF, RO, FO). The company supplies capital equipment and membrane modules, delivers Build-Own-Operate (BOO) and Operations & Maintenance (O&M) service contracts to industrial and municipal clients, and provides specialty chemicals and consumables through its acquired subsidiaries. Its primary end markets are mining, food & beverage, municipal/infrastructure, and other industrial sectors across Australia, Singapore, Germany, and broader Asia-Pacific.

Product overview

De.mem is a market leader in decentralized water and wastewater treatment, offering a comprehensive portfolio of proprietary hollow fibre membrane technologies and treatment solutions. The company provides both products (membrane technologies, equipment, chemicals) and services (BOOT contracts, operations & maintenance) to industrial clients. The core technology platform centers on proprietary hollow fibre membranes including Ultrafiltration (UF), Nanofiltration (NF), and Forward Osmosis (FO) technologies developed in partnership with Nanyang Technological University (NTU). These membranes are manufactured at De.mem's Singapore facility as standardized 8-inch or 4-inch modules, or as turn-key systems. Supporting the membrane products is the proprietary 'de.live' automation platform for monitoring and process control. The company operates under a 'One Stop Shop' model providing equipment (MBRs, RO, sludge presses), chemicals, consumables, and operational services including Build, Own, Operate, Transfer (BOOT) schemes. The product portfolio spans disinfection (chlorination, UV), biological treatment (MBBRs, SBRs, anaerobic), filtration (DAF, media, ion exchange), and specialized solutions (Zero Liquid Discharge). Through strategic acquisitions, De.mem has expanded into specialty chemicals (Core Chemicals, Capic), industrial services (Akwa-Worx, Auswater Systems), and geographic markets (De.mem-Geutec in Germany, De.mem-Pumptech in Tasmania, De.mem-Stevco in Victoria). The company serves diverse industrial sectors including mining, food & beverage, oil & gas, electronics, and municipal/infrastructure applications across Australia, Singapore, Germany, and Vietnam.
