Bio Aqua

What Bio Aqua does

Bio Aqua A/S is a privately held Danish industrial water treatment equipment and solutions company founded in 1999 and headquartered in Fuglebjerg, Denmark. The company designs, manufactures, and integrates custom water treatment systems for industrial customers across multiple verticals, including food and fish processing, aquaculture, dairy, biogas, landfill leachate, paint, and textiles. Its product portfolio centers on micro and nano bubble systems (sourced as the exclusive importer of Nikuni microbubble generators), flotation plants, bioreactors, aeration systems, screw press sludge dewatering, and ultrafiltration. Bio-Aqua combines these building blocks into industry-specific solutions, such as the BIO-ADVANCED SYSTEM for car wash water recycling (up to 90% water recovery), fish protein and oil recovery systems, leachate treatment trains, biogas reactors (claiming 4-5x yield per cubic meter), and ozonation systems for cheese brine disinfection. The company is led by CEO Erik Jürgensen, with over 30 years of experience and 3 patents on wastewater technology.

The business model is project-based and engineered-to-order. Revenue derives from one-time equipment sales (custom-designed and manufactured treatment systems), professional services including project design, piloting, installation, and ongoing maintenance contracts that may run multi-year. Pricing is custom per project, determined by water parameters, outlet quality requirements, and capacity, with a piloting period typically preceding final solution design. The go-to-market motion is direct enterprise field sales to industrial customers in Europe (primarily Denmark), with documented project deliveries reaching Southeast Asia (Malaysia) and North America (Canada). The customer base includes named enterprises such as Danish Crown, TripleNine, Royal Greenland, Skretting, Statoil, and a Canadian salmon processing plant. Bio-Aqua is part of a corporate group with Drying Matter (sludge and biomass drying) and Clean Matter (phosphorus recovery from ash), forming an integrated resource-recovery offering. Marketing is conducted primarily through its website and direct contact channels.

The firm operates with a small team of 1-10 employees, has no external institutional or venture capital backing disclosed, and is not listed on any public exchange. Patents are filed but pending status; no revenue figures are publicly disclosed.

Core offering

Bio Aqua designs, engineers, and supplies custom industrial water and wastewater treatment plants built around proprietary microbubble-based flotation, bioreactors, aeration, sludge dewatering, and ultrafiltration technologies. Beyond standalone equipment, the company delivers industry-specific turnkey solutions for food/fish processing, aquaculture, biogas, landfill leachate, paint, textiles, and car wash water recycling, supported by pilot testing, installation, rental/test units, and ongoing service and maintenance.

Product overview

Bio-Aqua is a Danish water treatment technology company founded in 1999, offering a portfolio of physical water treatment equipment and systems. The core product line includes micro and nano bubble systems (using Nikuni microbubble generators), flotation plants, bioreactors, aeration systems, screw press sludge dewatering, and ultra filtration systems. These technologies are combined into industry-specific solutions such as the BIO-ADVANCED SYSTEM for car wash water recycling, fish protein and oil recovery systems, leachate treatment, cheese brine ozonation, and biogas reactors. Bio-Aqua operates as an equipment manufacturer and systems integrator, delivering both standard units and custom-designed treatment plants for food/fish processing, aquaculture, landfill, biogas, paint, textile, and general wastewater industries.

Products and services

• Micro and Nano Bubble Systems Nano/microbubble generator systems (Nikuni-based with Bio-Aqua nozzles) used to increase oxygen content, support ozonation, drive flotation, and perform cleaning in industrial water and wastewater treatment. Intended for industrial water treatment customers and system integrators.
• Flotation Plants Rectangular and cylindrical flotation units combined with flocculation systems that separate solids and oils from water using microbubbles to lift particles to the surface for removal. Sold to industrial customers with wastewater streams containing suspended solids, oils, or recoverables.
• Bioreactors Aerated, submerged biofilm reactors available as stand-alone, buried, or floating units with integrated aeration for biological wastewater treatment. Targeted at industrial customers needing biological reduction of organic load.
• Aeration Systems Submerged aeration mixers for bioreactors and buffer tanks that distribute air 360 degrees at the bottom to prevent sedimentation, plus a microbubble oxygenator for high-rate oxygen introduction. For industrial wastewater and aquaculture users.
• Sludge Dewatering (Screw Presses) Screw press sludge dewatering machines where flocculated raw sludge is pumped into a screw cylinder with alternating fixed and moving rings, draining water through 0.5 mm gaps; slow-moving, energy-saving process with capacities from 10 to 300 kg DS/h. Sold to industrial and municipal sludge producers.
• Ultra Filtration Filtration systems using ceramic or flexible filter media for bacteria removal, water clarification, drinking water treatment, technical water, oil/water separation, and phosphorus capture. Targeted at industrial and utility customers needing fine solid-liquid separation.
• BIO-ADVANCED SYSTEM Integrated water recycling system for car wash facilities combining flocculation and biological treatment to recover up to 90% of process water, with strong reductions in heavy metals (Pb, Cu, Cd, Zn) and standard parameters (COD, BOD, TSS). Sold to car wash operators (e.g., Statoil Danish washing halls).
• Fish Protein and Oil Recovery System Two-step recovery system that concentrates fish protein and oil from unloading water of fishing vessels using a food-grade treatment step followed by traditional treatment, recovering valuable ingredients that would otherwise require costly evaporation or disposal. Sold to fish processing companies such as TripleNine.
• Leachate Treatment Systems Custom treatment systems for landfill leachate combining flocculation, flotation, screw press, and other technologies, designed through piloting periods to address variations in water types and local regulations. Sold to landfill operators.
• Ozonation of Cheese Brine System Ozone-based hygienic system that cleans and disinfects recirculated cheese brine by removing cheese particles and reducing bacteria and yeast counts, improving hygiene and final product quality. Sold to dairy processors such as cheese dairies.
• Flotation Unit Upgrade System (Dispersion Water Upgrade for DAF) Retrofit upgrade system using Bio-Aqua's dispersion water unit (Nikuni pumps with patented injection nozzles) to modernize existing dissolved air flotation (DAF) plants, delivering 20% lower energy consumption, 30% extra sludge removal, and 30–45% efficiency improvement. Sold to existing DAF owners such as Danish Crown.
• Fish Processing Water Treatment Turnkey water treatment solutions for fish processing plants covering blood water and filleting water, combining flotation, flocculation, and ozone disinfection with capability to enable re-use of valuable by-products. Sold to fish processors and developed in R&D partnerships with Royal Greenland and Skretting.
• Biogas Reactors and Downstream Treatment Super-efficient biogas reactors delivering up to 4–5x biogas yield per cubic meter, supplied together with downstream water treatment trains (trickling biofilter, flotation units, polymer preparation, aerators).
