Pure Water No.1

What Pure Water No.1 does

Pure Water No.1 (深圳市纯水一号科技股份有限公司, Shenzhen Pure Water No.1 Technology Co., Ltd.) is a Shenzhen-based industrial water-treatment equipment manufacturer and engineering contractor founded in 2002. The company designs, manufactures, installs, commissions, and services integrated ultra-pure water (UPW) production lines for high-purity industrial applications, composed of modular subsystems including pre-treatment (multi-media filter, activated carbon filter, automatic softener, UF, NF), automatic chemical dosing, reverse osmosis (RO), continuous electrodeionization (EDI), TOC removal, degassing membrane, polishing mixed bed, and a three-tier PLC-based automation layer. It also delivers adjacent solutions — seawater desalination, industrial wastewater treatment, industrial waste gas treatment, sludge deep treatment, landfill leachate treatment, and water-reuse (MBR) systems — supported by a consumables and replacement-parts catalogue built around third-party components from DOW FilmTec, Hydranautics, Norit, DuPont AmberLite/DOWEX and Siemens.

The company serves more than 1,000 enterprise customers across electronic-semiconductor, photovoltaic, LCD panel, lithium-battery new-energy, optical/optoelectronic, chemical, food & beverage, pharmaceutical, power and PCB industries in China, with branch offices in Beijing, Wuhan, Xi'an, Shanghai, Guangzhou, Changsha and Kunshan, an owned Xianning Environmental Protection Industrial Park, and selected Southeast Asia exposure. Revenue is generated primarily through project-based EPC contracts for custom-engineered systems (240–1,200-ton UPW capacity), with supporting streams from engineering and commissioning services, a "one-year warranty, lifetime maintenance" aftermarket, and an online parts/resins/membranes store; FY2021 revenue exceeded ¥200M, and the company has held National High-tech Enterprise, 2021 Shenzhen Specialized & Sophisticated SME (list entry #1226), and Grade 2 Environmental Engineering / Mechanical & Electrical Installation Contracting qualifications.

The company completed a share-system reform in June 2024, converting from a limited liability company to a joint-stock company (and renaming accordingly), and received a Cowin Capital-led funding round in January 2025 — actions consistent with preparation for further capital deployment, capacity build-out, and a possible eventual public listing, while remaining privately held at the time of disclosure.

Product overview

Pure Water No.1 (深圳市纯水一号科技股份有限公司) is an integrated water-treatment equipment manufacturer and engineering contractor — not a single-product SaaS company but a platform-plus-modules industrial offering. Its portfolio centers on a complete ultra-pure water (UPW) production line composed of modular subsystems: the Pre-treatment System (multi-media filter, activated carbon filter, automatic softener, UF and NF modules), the Automatic Chemical Dosing System, the Reverse Osmosis (RO) System, the EDI System, the TOC Removal System, the Degassing Membrane System, the Fine Treatment / Polishing System (anion/cation beds, mixed bed, polishing mixed bed), and the Circuit / Electrical Control System (PLC-based automation). These modules are assembled into industry-specific solutions — Electronic-Semiconductor UPW, Photovoltaic Solar UPW, Flat-Panel Display UPW, Lithium-Battery New-Energy UPW, Optical/Optoelectronic UPW, and Water Reuse — and delivered alongside standalone project capabilities in Seawater Desalination, Industrial Wastewater Treatment, Industrial Waste Gas Treatment, Sludge Deep Treatment, and Landfill Leachate Treatment. The equipment is supported by a Consumables / Parts Mall (resins, RO/UF membrane elements, EDI modules, UV sterilizers, instruments) and a 7×24×365 service network across Shenzhen HQ and offices in Wuhan, Xi'an, Shanghai, Guangzhou, Changsha, and Kunshan. The company was founded in 2002, restructured into a stock company in June 2024, and has served more than 1,000 enterprise customers in electronics, photovoltaic, LCD, new energy, chemicals, pharmaceuticals, food & beverage, and other sectors.
