Delft water-purification method promises radical improvement

Delft University of Technology research has discovered a method that could drastically change the way we purify water within a few years. Delft, in partnership with DHV engineering bureau, has developed a compact and environmentally-friendly purification method, in which aerobic bacteria form granules that sink quickly. An important part of the project's success was the work of Delft researcher Merle de Kreuk, who, on Tuesday, 27 June, will receive her PhD degree based on this research subject.

With the new aerobic granular sludge technology (Nereda TM), aerobic (thus oxygen using) bacterial granules are formed in the water that is to be purified. The great advantage of these granules is that they sink quickly and that all the required biological purifying processes occur within these granules.

The technology therefore offers important advantages when compared to conventional water purification processes. For example, all the processes can occur in one reactor. Moreover, there is no need to use large re-sinking tanks, such as those used for conventional purification. Such large tanks are needed for this because the bacteria clusters that are formed take much longer to sink than the aerobic granule sludge.

According to Delft PhD researcher Merle de Kreuk, a Nereda TM purification installation needs only a quarter of the space required by conventional installations. Moreover, Nereda TM uses 30% less energy than the normal purification process. This Nereda TM purification process is suitable for both domestic and industrial waste water.

Delft University of Technology has a long tradition in researching the possibilities of water purification with aerobic granular sludge. The maturation of the technology is largely due to the research conducted by De Kreuk. During her PhD research with Prof. Mark van Loosdrecht, De Kreuk ?working together with DHV engineering bureau and supported by STOWA and STW grants ?solved various technological bott
