Research and Development Projects
AMASING: Ceramic, high-flux microfiltration membrane
The objectives of the project is further development of the LiqTech SiC membrane. Together with our partner Technical University of Denmark, ceramic engineering and science, the aim of the project is to remove roughness and macropores in the membrane layer by optimizing dispersion and stabilization of SiC powder in the aqueous suspensions.
Furthermore, it aims at understanding the relation between the surface chemistry of the SiC powders and the membrane and the relation between the surface chemistry of the membrane and its microporosity, filtration efficiency (cut-off) and tendency to foul.
For the testing of the membrane LiqTech International is collaborating with a Chinese partner working in the biopharmaceutical industry.
LiqTech produces advance ceramic membranes made of silicon carbide (SiC).
AMASING aims to make tighter membrane which would improve the membrane performance.
LiqTech International teamed up with some of the biggest water companies and knowledge institutes in Denmark for the purpose of reducing water use in food industry.
DRIP – Danish partnership for Resource and water efficient Industrial Food Production – is a public/private partnership focused on water efficiency in the food industry, one of the largest water-consuming industries in Denmark and globally.
The partnership’s ambition is to produce more with less water. DRIP will reduce water consumption in leading Danish food producers by developing new sustainable water and production technology solutions and concepts.
The ambition is to use significantly less water of drinking water quality and increasingly use recycled water without compromising product quality and food safety. The developed technologies and solutions will be tested in pilot or full-scale under production conditions. The goal is a reduction in water consumption of 15 – 30 %.
Once the technologies are developed, the ambition is to create new export successes for the Danish technology and knowledge providers in the water area while at the same time the competitiveness of the food producers should be improved.
The partnership consists of a number of food companies and technology providers, three universities and two GTS institutes (research and technology organization).
The Danish Veterinary and Food Administration, Environmental Protection Agency and Nature Agency are associated partners. The partnership was launched March 1, 2015 under the INNO+ societal partnership framework with an investment of DKK 50m from Innovation Fund Denmark and DKK 48m from the partners.
– Development of filtering technologies for microalgae and sustainable high quality feed for fry
There is an urgent need for alternative resources to fishmeal and fish oil for the production of fish feed to the aquaculture industry. The resource problem is due to a combination of the rapid growth of the aquaculture, and the fact that catches of fish for the feed industry is stagnating.
The idea to use microalgae as fish feed originated from an on-going EU-project, which aims at demonstrating that algae can be grown on process water from the industry.
The partners in the project will develop, test and demonstrate new technologies for harvesting and refining microalgae. The project will develop a technology to open the cell walls of the microalgae in order to make it possible to extract micro- and macronutrients for use as an alternative resource to fish oil and fishmeal in the production of fish feed for the aquaculture industry.
The project is coordinated by the National Food Institute, Technical University of Denmark.

LiqTech International A/S
LiqTech International joined Horizon2020 consortium as a partner with vast experience within the field of ceramic membranes. SiC material will be used in a new reactor concept to drastically reduce energy consumption.
The ROMEO project tackles process intensification for catalytic-driven and eco-friendly reaction systems.
ROMEO stands for “Reactor Optimisation by Membrane Enhanced Operation”. It is a Research and Innovation project and has received funding from the European Union’s Horizon 2020 research and innovation programme.
ROMEO focuses on a new reactor concept to drastically reduce energy consumption. It will lead to the manufacturing of bulk chemicals at considerably lower operational and investment costs.
The aim of ROMEO is to reduce energy consumption by up to 80% and emissions by up to 90% in industrial catalytic gas-phase reactions.
ROMEO’s 9 partners team up for 4 years to demonstrate the technical feasibility of this reactor concept.
The project started in September 2015 with an EU budget of 6 million euros.
The organisation of the 8 work packages (WP) is presented below:
– An Integrated Membrane Process for Oily Wastewater Treatment, Water Reuse and Valuable By-Products Recovery.
LiqTech International is leading the EU Fp7 project O-WaR, in a consortium that consist 7 other partners including 3 SME´s, 2 knowledge institutes and 2 end users.
The O-WaR (Oily Wastewater Reuse) project aims to develop an integrated process able to efficiently remove highly emulsified oil from wastewater, to reuse treated wastewater, to recover valuable by- products in wastewater and to reduce volumes of oily waste for disposal.
A large amount of wastewater in the form of oil-in-water is generated in different industries such as vegetable oil, metal processing, transportation, petrochemical and oil and gas (where the oily wastewater is called “produced water”). These oily wastewaters also feature high chemical oxygen demand (COD) and high suspended solids (SS).
All the industries face the same problems: to separate emulsified oil from water in a cost-effective way and to handle large volumes of oily waste in an economical way.
Conventional approaches for treating oily wastewaters include gravity separation, skimming, dissolved air flotation, de-emulsification, coagulation and flocculation. Membrane processes are also increasingly used for treating oily wastewater.
Membrane processes exhibit undisputable advantages over the conventional approaches, especially in treatment of highly emulsified oily wastewater: little energy consumption, small footprint and most importantly, nearly complete removal of oil in wastewaters.
However, membrane processes have not been widely accepted by the industries and the major inhibiting factor for successful commercialisation of membrane processes is membrane fouling. Membrane fouling is caused by adsorption and deposit of some components in feed water on the membrane surface and/or in the membrane matrix.
Membrane fouling results in membrane flux decline over time and eventually membrane replacement (after a number of chemical cleaning cycles). Although ceramic membranes, due to their hydrophilic membrane surface, are less prone to fouling than polymeric membranes, quickly declined fluxes of ceramic membranes have also been observed in many oily wastewater treatment studies 1,2,3.
– Pelagic Industry Processing Effluents Innovative and Sustainable Solutions
The main goal for the PIPE project is to test cutting edge technologies, to separate water and organic material from pelagic industries effluents and to characterize as well as valorise the organic material collected.
For this project LiqTech International collaborated with Technical University of Denmark as well as Jiaotong top 100-rated university in engineering, Chalmers University of Technology from Sweden.
The main objectives of the PIPE project are to:
(i) test technologies such as ceramic membranes and electrochemistry for their efficiency in separating organic matter from effluents from marinated herring production, (ii) characterize the chemical composition, antioxidant activity and functionality of different streams and fractions before and after separation and (iii) evaluate the market potential for the recovered fractions.
Throughout the PIPE-project, effluent streams covering all steps in the marinated herring production i.e. from boat to the final marinated products, have been carefully characterized including different products type and over different seasons. Several pilot scale separation trials have also been carried out, and the fractions generated have been investigated for their basic composition, antioxidant activity and functional properties.
