HAOP adsorbent - innovative new water treatment technology – application in circular economy projects

European Call(s)


Name of the organisation

Aquateam COWI

Description of the organisation

Non-profit R&D organisation; Test body for qualifying water treatment technology for different applications (Drinking water, wastewater, industrial wastewater, water in oil/gas/mining, surface run-off, seepage water from landfills, water from aquaculture and fish processing), for sludge treatment (biogas, biosolids and fertilisers), treatment of contaminates sites and sediment. Environmental Risk assessment and ecotoxicology testing (toxicity, bioaccumulation, degradation and leakage). Long term experience from developing Guidelines and supporting industry and society. Long term experience from supporting technology vendors in documentation and testing of emerging technology. Close cooperation with Universities and End-users, chemical suppliers and technology vendors. More than 30 years' experience with emerging environmental technologies related to water.

Main areas of expertise

HAOP; HIOP = Heated Aluminium (Iron) Oxide Particles behaviour; Collaboration with SME from USA; MicroHAOPs. Several PhDs and Master Studies of various applications.

Water treatment technology
• Basic process understanding (alternative to all applications of Al and Fe coagulants)
• Technology qualification
• Automation and control
• Lab scale and initial prototype testing experience from treatment of surface water for drinking water (hygienic barrier and hindering of membrane biofouling)

Speciality chemical production
• HAOP/HIOP production process in lab scale

Technology testing and verification
• Removal of Natural Organic Matter (NOM) from drinking water - early phase testing prototype
• P-recovery from Wastewater – lab-scale initial work
• Controlling membrane biofouling when treating seawater and freshwater – small scale testing

Looking for: Partner(s)

• Speciality Chemical Vendors
• Water Treatment Technology Vendors
• Testing bodies/laboratories
• University and/or R&D Institutes
• End-users


Austria - Belgium - Finland - France - Germany - Ireland - Italy - Luxembourg - Netherlands - Poland - Portugal - Sweden - Norway

Main Objectives:

• Establishing a European Network of universities, innovative industries (chemical- and water treatment technology vendors), end-users and test- and verification bodies.
• Document cost/beneficial applications for the HAOP technology, establish and prioritise a development plan including short-term and long-term goals
• Establish a market plan for the short term prioritised applications of HAOP
• Continue development work of the emerging HAOP technology in prioritised areas and expanding it to new application areas
• Establish a market and industrialisation network bringing the products to the market.
• Collaborate with the network ensuring developing the most cost/efficient solutions to support circular economy and meet the needs of society.


A joint R&D project was established in 2015 between a group of experts from an American university and Aquateam COWI and a Norwegian group of experts including one Norwegian University and an End-user for the technology. The first protoype will be tested in 2018 for treatment of drinking water. The Norwegian and American expertise see a many possible opportunities for the core technology (HAOP) in many interesting application areas related to the circular economy concept. The costs, resources and time associated with preparation of prototypes and verification of technology for different application areas is the major challenge for the impact of the project. A focussed effort is needed. We need to establish a network including the right companies to collaborate within Europe (innovative and focussed), who also is able to bring the products to the market. The network needs to include innovative European Universities covering different application areas. It also need to include testing and verification bodies covering different application areas/markets, and different end-users. This way, we can speed up the developing process and limit the resources needed.

Previous EU experience:

• WaterNanoNet- "Network of Nano chemical sensors and Nano water cleaning/energy generating technology supporting eco-intensive inland and coastal zone aquaculture". Second stage proposal submitted on 13th September 2017, to the Call: H2020-SFS-2016-2017. The overall objective of the WaterNanoNet project is to develop an innovative network of sensors, water-cleaning products, antimicrobial materials and skills/knowledge, operated by the aquaculture industry to support circular economy intensive aquaculture production. Coordinator role.
• O-WaR - “An integrated membrane process for oily wastewater treatment, water re-use and valuable by-products recovery”; EU Research for SME (FP7-SME-2013; Project number 605641), 2014-2015. The aims of the project was to develop an integrated process for removal emulsified oil from wastewater, to reuse treated water, to recover by-products in wastewater, to reduce volumes of oily waste for disposal and to improve the quality of discharged wastewater. Research was aimed for the benefit of specific group (Small and Medium Enterprises) related to treatment wastewater in the rural areas with limited access to proper methods wastewater treatment. Partner role.
• Operation SWAT – "Salsnes Water to Algae Treatment technology: high recovery of microalgae from water phase" (FP 7: Research for SMEs, 2011-2013). The objective was to develop a universal algae harvesting technology by building on the experiences gained from the SME partners on removing particles from wastewater, and by modifying wastewater treatment technologies to harvest microalgae. The project used a flocculator followed by a Salsnes Filter to harvest algae. Two RTDs (Aquateam and HERI) carried out research and development to achieve the objective. Two test sites have been chosen (IGV in Germany and Aqualia in Spain) to test the SWAT technology. Partner role.
