CWT China

What CWT China does

CWT China (legal name: Clean Water Technology (China) Limited Liability Company; 美吕净水技术（上海）有限公司) is the Shanghai-based Chinese subsidiary of Clean Water Technology, Inc., a California-founded (1996) industrial wastewater treatment firm that sits within the Marvin Group (马文工程集团). Established in 2012, the entity localizes sales, engineering, container equipment assembly, and after-sales service for the Chinese industrial market, while core R&D and additional manufacturing remain anchored at the parent's Los Angeles headquarters and a large-scale integration plant in Bogotá, Colombia. The company's go-to-market is B2B enterprise field sales targeting large industrial clients, multinational corporations, and engineering firms across verticals including metallurgy/steel, daily chemicals/cosmetics, machining/aerospace, petrochemical/oil & gas, food & beverage, aviation catering, and seawater desalination.

The technical core is the proprietary GEM® (Gas-Energy Flocculation) system, a vortex three-phase mixer–based flotation platform released in 2003 and protected by 20+ patents globally, marketed as achieving 99% oil removal, 99% turbidity reduction, and a 90% footprint reduction versus traditional processes. The product portfolio extends to Swingmill® double-screw sludge dewatering equipment, MBR / SMF / UTO membrane modules, biological deodorization systems (15-year filler life, 1/20 the operating cost of chemical deodorization), RO-based seawater desalination (50–67% lower capex, ~20% lower energy consumption), and a "plug-and-play" container modular equipment line supported by financial leasing. Service revenues are derived from water analysis and pilot-scale process development, supply of chemical consumables and spare parts, and an Operation & Management offering with mobile/tablet monitoring and 24–48 hour emergency response, creating a recurring layer on top of one-time equipment sales.

Revenue mechanics are dominated by project-based equipment sales to enterprise customers, supplemented by managed services, consumables, and leasing. The China subsidiary itself is staffed by a small core team (5 listed employees, with active recruitment underway for additional process engineers and technical managers). Marquee global reference customers at the parent level include Nestlé, Tesla, DuPont, and Singapore Airlines, alongside a stated 850+ global customer base. No public pricing, no revenue disclosure, and no external funding rounds appear in the input data, consistent with CWT China operating as a wholly-owned subsidiary within a privately held US technology conglomerate.
