FG Water Technologies  |  Wuxi Fenigal Science and Technology Co. Ltd.

Industrial Water Systems and Membrane Technologies

FG Water Technologies is the industrial water business division of Wuxi Fenigal Science and Technology Co. Ltd., based in Wuxi, Jiangsu, China. We supply water treatment components and integrated equipment for industrial water purification, high-purity water production, brackish water and seawater desalination, and wastewater treatment and reuse.

Our core business brings together branded electrodeionization (EDI) stacks, DuPont ultrafiltration membranes, ultrapure water systems, brackish water reverse osmosis (BWRO), seawater reverse osmosis (SWRO), ultrafiltration equipment, membrane bioreactor (MBR) elements and assemblies, and high-pressure pumps. Customers can work with us for an individual replacement component, a packaged treatment unit or a coordinated process system.

We combine technical selection, international product sourcing and system integration with specialist manufacturing partners. This approach connects membrane and equipment supply with project requirements, from feedwater conditions and target water quality to installation, operation and maintenance.

Branded EDI Stacks and Packaged EDI Equipment

We supply branded EDI stacks and modules, including Veolia E-Cell and Ionpure products, together with packaged EDI equipment for continuous deionization of suitably pretreated RO permeate. Our scope includes new-system module selection, replacement requirements and integration with RO and high-purity water treatment systems.

EDI combines ion exchange resins, ion-selective membranes and direct current to remove residual ionic impurities without routine acid and caustic resin regeneration. We assess capacity, feedwater conductivity, hardness, silica, carbon dioxide and temperature, as well as electrical and hydraulic interfaces, to match the module to its operating duty. Selected Chinese-made EDI alternatives can also be evaluated where the project permits.

DuPont Ultrafiltration Membranes and Complete UF Systems

DuPont ultrafiltration membrane modules are a key part of our membrane supply business. We support module selection and replacement planning, as well as their integration into complete UF systems for surface water treatment, RO pretreatment, seawater desalination pretreatment and suitably pretreated reclaimed water.

UF systems remove suspended solids, colloids and microorganisms according to membrane characteristics and system integrity. Packages can incorporate feed pumps, membrane racks, air scouring, backwashing, chemically enhanced backwash and clean-in-place equipment, with instrumentation and automatic controls selected for the application.

Core Water Treatment Equipment

High Purity and Ultrapure Water Systems

We configure high-purity and ultrapure water systems around the quality required at the point of use. Depending on feedwater and application, the treatment train can combine pretreatment, single-pass or double-pass RO, EDI, mixed-bed polishing, UV treatment and final filtration, with storage and distribution equipment where required.

Applications include electronics manufacturing, laboratory and process water, pharmaceutical production and power plant boiler makeup. System selection considers resistivity or conductivity, silica, sodium, total organic carbon and microbiological requirements where applicable. Water quality and acceptance criteria are defined for each project; pharmaceutical and other regulated uses require the appropriate design and validation scope.

BWRO and SWRO Desalination Systems

Our reverse osmosis equipment covers BWRO for brackish groundwater and industrial process water, and SWRO for seawater desalination. We offer skid-mounted, containerized and portable configurations, with single-pass, double-pass or modular arrangements to suit site conditions and operating demand.

A complete package can include pretreatment, cartridge filtration, high-pressure pumping, RO membranes and pressure vessels, chemical dosing, flushing, clean-in-place equipment, instrumentation and PLC controls. SWRO projects can incorporate energy recovery and appropriate corrosion-resistant materials. Post-treatment is configured for the intended use, including remineralization or disinfection where required.

MBR Membrane Elements and Assemblies

We supply MBR membrane elements, modules and assemblies for municipal and industrial wastewater applications, and support their integration into treatment and water reuse systems. MBR combines biological treatment with membrane solid-liquid separation to retain biomass and produce a low-suspended-solids effluent.

Selection takes account of wastewater characteristics, required capacity, membrane flux, aeration, cleaning and module layout. Nutrient removal depends on the biological process design. Where the reuse target requires further treatment, MBR effluent can be combined with RO, disinfection or other polishing stages.

High Pressure Plunger and Axial Piston Pumps

High-pressure pump supply supports our RO and desalination business. The scope covers high-pressure plunger pumps and axial piston pump solutions for applicable duties, including Danfoss pump options for suitably matched seawater desalination systems.

We assess pressure, flow, feedwater salinity and temperature, wetted materials, drive requirements and maintenance access. Pump selection is coordinated with membrane operating conditions, inlet filtration and, where applicable, energy recovery equipment. Individual pumps can be supplied for new equipment, replacement or system upgrades.

Applications Manufacturing and Project Support

Supporting Treatment Equipment

Supporting equipment includes multimedia and activated carbon filters, iron and manganese removal units, softeners, cartridge, bag and disc filters, ion exchange and mixed-bed demineralizers, UV and ozone equipment, dosing systems and consumables.

Wastewater and reuse packages can include clarification, dissolved air flotation, aeration, sludge handling and advanced treatment equipment. Each unit is selected to coordinate pretreatment, membrane separation and post-treatment.

Industries and Applications

We serve industrial and commercial customers, equipment manufacturers, engineering contractors and plant operators. Applications include:

·       Power generation and boilers: demineralized makeup water, RO, EDI and water reuse.

·       Electronics and manufacturing: high-purity process water and ultrapure rinsing water.

·       Pharmaceuticals, food and beverages: water purification for production requirements.

·       Marine and coastal facilities: desalination for vessels, islands, resorts and offshore sites.

·       Chemical, mining, metal, pulp and paper industries: process water and wastewater reuse.

·       Municipal and commercial facilities: surface water, brackish water and sewage treatment.

Coordinated Manufacturing and Quality Control

Our manufacturing model draws on specialist partner facilities for large-scale RO, UF and MBR equipment, containerized and portable systems, filtration and ion exchange equipment, and disinfection and other supporting units. We coordinate component selection, fabrication requirements, assembly and inspection around the agreed project specification.

Quality control covers equipment configuration, material suitability, assembly checks and agreed pre-shipment functional tests. Documentation and acceptance criteria are established for each order, with attention to installation interfaces and maintenance access.

Technical and Commercial Project Support

We support customers with requirement review, process selection, equipment configuration, technical proposals, component supply and coordinated export delivery. Installation and commissioning support, operating guidance, spare parts and upgrade assistance can be included within the agreed scope.

Our aim is to provide components and treatment packages that suit the duty and are practical to install, operate and maintain.
