FDT

What FDT does

FDT S.r.l. is an Italian custom-engineered industrial water treatment systems manufacturer founded in 1967 and headquartered in Brugherio (Milan metropolitan area) on a 6,000 square meter campus combining design offices, factory, and warehouse. The company designs and manufactures bespoke water treatment equipment for industrial and public-sector clients, with a product portfolio spanning self-cleaning and specialty filters, water softening and demineralization systems (including mixed-bed and electro-deionization), reverse osmosis, UV sterilization, chlorine dioxide disinfection, biological wastewater treatment, containerized treatment plants, dosing systems, skid-mounted gas turbine compressor washing systems, and a proprietary line of treatment chemicals including FDA-compliant products.

The business operates on a project-based B2B model driven by direct enterprise field sales and technical consultation. Each system is engineered to client specifications and delivered with basic and detail engineering, fabrication, installation assistance, commissioning, and post-sales service. Revenue is generated through one-time equipment sales, professional engineering and installation services, recurring technical support contracts and chemical consumables supply, and pilot plant feasibility studies. The customer base spans public-sector entities (thermal power stations, hospitals, aqueducts, municipalities, provinces) and private industrial operators across refineries, chemical/pharmaceutical/cosmetic, food processing, paper mills, steelworks, textiles, and tanneries — with a separate FDT Homecare Division targeting residential customers. FDT holds ISO 9001 certification issued by RINA, operates primarily within Italy and Europe, and is a wholly-owned subsidiary under the direction and coordination of Culligan International Company (via Culligan Acquisition Italy srl), having previously been under GRUNDFOS Water Treatment Italy Srl.

Products and services

• Self-Cleaning Filters (Filtri autopulenti) Industrial automatic self-cleaning filters that remove suspended solids from surface waters, well water, and wastewater. Used for pre-filtration for ultrafiltration and reverse osmosis, cooling towers, heat exchangers, and irrigation applications.
• Activated Carbon Filters (Filtri carbone attivo) Filters using activated carbon adsorption to remove contaminants from water, leveraging the porosity and chemical reactivity of activated carbon derived from organic plant or animal substances.
• Cartridge Filters (Filtri a cartuccia) Line filters constructed entirely of stainless steel AISI 316, including containers for model cartridges and sanitary containers for standard model cartridges.
• Cyclone-Type Filters (Filtri a ciclone) Hydrocyclone filters using centrifugal force to separate suspended solids with higher specific weight, with fully automatic self-cleaning operation and filtration degrees of 30-50 microns.
• Water Softeners (Addolcitori) Water softeners containing ion exchange resins that transform encrusting calcium and magnesium salts into neutral non-encrusting salts, preventing scale formation in equipment and pipes.
• Reverse Osmosis Systems (Osmosi inversa) Semi-permeable membrane filtration systems for desalination and high-quality demineralized water production, with low operating costs, no chemical use, and complete removal of organic substances. Two-stage process can produce ultrapure water.
