On Tuesday 17 May, the University of Twente (UT) opened a membrane filtration pilot unit at the Enschede wastewater treatment facility.\u00a0This is part of the research being carried out by the Applied and Engineering Sciences department of the Dutch Research Council into new technology for the filtration of organic micro-pollutants.<\/a>\u00a0One of the things that PhD research scientist\u00a0Hans David Wendt is studying is the process that breaks down the contaminated water that is left from the membrane filtration in a bioreactor, writes UT in a press release<\/a>.<\/p>\n\n\n\n

When you take medicines, you expel a lot of the active substances when you urinate. Those small, organic molecules are examples of micro-pollutants. When they get into the water, these drug residues are harmful not only to humans but also to life in and around the water. \u201cWe aren\u2019t talking about just one substance but a large cocktail of possibly thousands of different substances\u201d, says UT researcher Hans David Wendt.<\/p>\n\n\n\n

Nano-sieves<\/h3>\n\n\n\n

The University of Twente has been carrying out research for many years into the development of membranes for purifying water and removing the cocktail of micro-pollutants.<\/a>\u00a0A membrane \u2013 a sort of very fine sieve \u2013 allows only water and some minerals to pass through. However, the residual water that remains has a higher concentration of drug residues, which requires further treatment. \u201cIn this project we aim to tackle this residual water by sending it back to a bioreactor, where the drug residues are broken down\u201d, says Wendt. \u201cA bioreactor is frequently already installed at wastewater treatment facilities but is unable to break down the drug residues adequately. Sending the water back increases the time available to the bioreactor to break down the substances. That will therefore enable total removal.\u201d<\/p>\n\n\n\n

Wastewater treatment facility in miniature<\/h3>\n\n\n\n

The pilot is a miniature version of the present wastewater treatment facility in Enschede, with the addition of the new membrane filtration unit. The entire system was designed in partnership with Nijhuis Saur Industries, which subsequently built it. This plant will filter one thousand litres per hour. That is substantially more than in the laboratories at UT. \u201cAlong with all the partners we want to find out whether the technology works in practice on a larger scale\u201d, Wendt adds, \u201cWe\u2019re working with genuine wastewater, so we hope to get results that you cannot see in the laboratory.\u201d The plant is based on membranes for which the basis was developed at the UT, and which are being deployed globally by NX Filtration.<\/p>\n\n\n
