Global pump and water technologies leader, Grundfos Pumps has been awarded a S$1.4 million grant by the Singapore Environment and Water Industry Programme Office (EWI) to carry out a research project aimed at reducing capital investment and operational costs for wastewater treatment.

Grundfos has been awarded the grant under the National Research Foundation’s Incentive for Research and Innovation Scheme (IRIS). The scheme is administered by EWI, which is led by PUB, Singapore’s national water agency and various partner agencies. Besides funding the R&D, the grant will cover a pilot demonstration of the technology upon successful proof of concept.

Grundfos will develop a novel wastewater filtration technology with the R&D project focussing on the industrial treatment of wastewater using a unique cake filter made from activated sludge. Activated sludge is the ‘active ingredient’ of a biological wastewater treatment plant, which contains a suspension of bacteria that feed on wastewater impurities, thereby cleaning it.

Unlike conventional technologies such as ultra filtration, which require a lot of energy and maintenance during operation, Grundfos’ cake filtration technology requires very little energy as it can operate under the low water pressure generated by gravity.

Cake filtration produces superior filtrate quality that can be safely discharged into the sea. There is further potential to treat the filtrate and recycle it for irrigation or industrial uses. Grundfos’ technology is expected to fit in with a broad range of solutions for water treatment, and wastewater discharge and recycling. The R&D will enable the development of a suite of wastewater treatment solutions.

The project will be carried out by the Grundfos Water Innovation Centre in Singapore headed by Dr Gao Xin, with support from the Nanyang Technological University’s Nanyang Environment & Water Research Institute (NEWRI), a world-leading research institute in the areas of water and environmental technologies.

Mr Lars Enevoldsen, Group Vice President of Grundfos Global Research and Technology, looks forward to taking Grundfos’ research on the cake filtration technology to its next level as a cost-effective solution for the treatment and re-use of wastewater, and is confident they will set new research benchmarks in both Denmark and Singapore through this collaboration.

Mr Okay Barutçu, Regional Managing Director of Grundfos Asia Pacific, commented that Grundfos has been addressing the world’s water challenges as a major technology and solutions provider, in addition to being a pump company. Observing that Grundfos is continuously developing new technologies, which will not only improve the responsible use of water, but also greatly optimise the cost and energy consumption of recycling water, he added that they are proud to be partnering with PUB and NEWRI in this important project.

Prof Ng Wun Jern, Executive Director of NEWRI, said research collaboration with world leading companies such as Grundfos would allow research to move beyond the generation of knowledge and to apply as solutions that are of great value to the industry.
