What SIGMADAF Clarifiers does

SIGMADAF Clarifiers, S.L. is a privately held Spanish industrial wastewater treatment equipment manufacturer headquartered in Cornellà del Terri, Catalonia, operating as part of the SIGMA GROUP conglomerate. Founded in 2004 with approximately 26 employees, the company designs and produces Dissolved Air Flotation (DAF) systems, induced-air flotation (CAF/ACAF) units, membrane bioreactors (MBR), moving bed biofilm reactors (MBBR), fluidized bed reactors (FBR), and filter presses for sludge dewatering. All manufacturing is conducted in-house at company-owned facilities totaling 12,000 m², which also house an integrated laboratory, pilot plants, and a training center. The product range spans from compact plug-and-play units for decentralized treatment to multi-stage plants, with the company reporting 1,500+ units cumulatively supplied across 40+ countries over 30+ years of industry experience.

The company's primary end markets are industrial verticals with high organic or hydrocarbon loading: agri-food and beverages (meat, dairy, beverages, collagen/gelatin), oil & gas and petrochemical (refineries such as those of Repsol and Pemex), municipal and desalination pre-treatment, metal and mining, textile and leather, pharmaceutical and cosmetics, and energy/power. Core customers include large industrial operators and EPC contractors such as Repsol, Veolia, Suez, ACCIONA, Técnicas Reunidas, PepsiCo, Rousselot, Befesa, and Efacec. Distribution is executed through direct enterprise field sales supported by wholly-owned regional offices in Spain, the USA, Mexico, France, Colombia, Peru, Argentina, and Tunisia. SIGMA GROUP sister entity AGUASIGMA provides turnkey design, assembly, and commissioning services, allowing SIGMADAF equipment to be embedded in full WWTP project delivery.

Revenue is generated primarily through one-time equipment sales of custom-configured DAF and biological treatment systems complemented by professional services across the equipment lifecycle — laboratory testing, pilot trials, factory acceptance testing (FAT), commissioning, start-up, spare parts, and after-sales support delivered through the in-house training center. Pricing is not publicly disclosed and is quoted on a project-by-project basis. The company maintains industry memberships in The Water Council, CWP, INNOVACC, and the UN Global Compact, and exhibits at IFAT. Revenue figures, funding events, and detailed headcount trends are not publicly disclosed.

Functional benefit

Products and services

• DAF Systems (Dissolved Air Flotation) Dissolved Air Flotation systems for industrial wastewater clarification, available in standard, polypropylene, compact physicochemical, and U-shaped configurations. Removes suspended solids, oils, greases, and contaminants through micro-bubble flotation. Used by industrial facilities across food & beverage, oil & gas, metal, textile, pharma, and municipal sectors.
• CAF / ACAF (Induced Air Flotation) Induced air flotation systems (including the ACAF-25 grease separator) for wastewater pretreatment, particularly effective for oil and grease separation without complex mechanical equipment. Designed for simple operation with very low maintenance cost.
• MBR Membrane Bioreactor Systems Compact membrane bioreactor systems combining biological treatment with membrane filtration to produce high-quality effluent for industrial and decentralized wastewater applications.
• MBBR (Moving Bed Biofilm Reactor) Biological treatment system using suspended carrier media for biofilm growth, suitable for decentralized and industrial wastewater treatment plants.
• FBR Bioflotation Systems Fluidized Bed Reactor combined with bioflotation for biological wastewater treatment and integrated sludge separation.
• Filter Presses Filter presses for sludge dewatering from municipal and industrial wastewater treatment plants, reducing sludge volume for easier handling and disposal.
• Decentralized STP Plants Pre-assembled, modular and scalable plug-and-play sewage treatment plants for decentralized wastewater management with reduced footprint.
• Compact Membrane Filtration Plants Compact membrane filtration systems for advanced water purification and tertiary treatment applications.

Broad incumbents

• Alfa Laval: Swedish multinational with a large separation and fluid handling portfolio serving industrial water and wastewater applications. Competes with SIGMADAF in protein processing, oil & gas, and industrial wastewater separation, but as part of a much broader industrial equipment portfolio.
• Andritz: Austrian separation and process equipment manufacturer with strong wastewater and sludge treatment exposure. Serves similar industrial customers (food, chemical, municipal) but from a global, multi-segment scale rather than a specialization in DAF.
• Xylem: US-listed global water technology company (parent of Wedeco, Evoqua assets) with a portfolio spanning treatment equipment, filtration, and digital water. Competes with SIGMADAF in industrial and municipal wastewater, but at vastly greater scale and breadth.
• Veolia Water Technologies: Global water treatment giant and SIGMADAF customer. Both supplies and competes with DAF and biological treatment equipment, but operates as a full-solutions EPC player with its own manufacturing and service network.

Direct peers

• Toro Equipment: Spanish-headquartered manufacturer of DAF, lamella, and sludge treatment equipment serving industrial and municipal markets. Closest direct competitor in geography, product mix, and target customer base.
• WEDA Water & Environment: Swedish manufacturer of DAF systems and biological treatment equipment for industrial and municipal wastewater. Highly comparable to SIGMADAF in core product (DAF), customer verticals (food, industrial, municipal), and integrated project delivery model.
• Smith & Loveless: US manufacturer of packaged wastewater treatment plants, DAF systems, and filtration equipment for municipal and industrial customers. Comparable in offering modular, factory-built treatment systems with project delivery.
• Hydro International: UK-based manufacturer of water treatment and separation equipment including DAF and lamella clarifiers for industrial and municipal applications. Overlaps directly with SIGMADAF's flotation and sludge handling product lines.

Emerging players

• DAF Corporation: Specialized North American DAF equipment manufacturer focused on industrial wastewater clarification. Comparable in core technology but with a narrower product set and regional focus than SIGMADAF.
• Ecologix Environmental Systems: US-based provider of packaged and custom wastewater treatment systems including DAF and biological reactors. Similar SMB/mid-market industrial customer focus and modular delivery model.
