This paper reports on the potential for water reuse in the malting sector. Core unit of a treatment train to close the water loop was a membrane bioreactor (MBR). We compared three different commercial submerged membranes for their fouling potential in this application and related this to the presence of extracellular polymeric substances (EPS). In a second step, we subjected MBR permeate to reverse osmosis and several (advanced) oxidation processes to evaluate the water quality achieved. Finally we performed a set of water reuse tests with waters obtained through different scenarios. The optimal scenario was then tested in a closed water loop over several malting cycles at pilot scale and the effect on water and malt quality was investigated.

This paper reports on the potential for water reuse in the malting sector. Core unit of a treatment train to close the water loop was a membrane bioreactor (MBR). Three different commercial submerged membranes were compared in terms of their fouling potential in this application. In a second step, MBR permeate was subjected to reverse osmosis (RO) and several oxidation processes. Neither the MBR permeate nor the RO permeate or oxidized water streams showed an adverse effect on malt quality. The worst case scenario was then tested in a closed water loop over several malting cycles at pilot scale and the effect on water and malt quality investigated.

OH radicals are the key oxidants that control most Advanced Oxidation Processes (AOPs) currently applied in water technology and that also occur in some natural systems such as cloud waters. The efficiencies of the various OH radical sources can be experimentally quantified and compared when they are calibrated by following the oxidation of inter-calibrated reference compounds that react during the process only with OH radicals. To apply and generalize the results, however, water quality parameters controlling the lifetime of OH radicals via OH-scavenging reactions by pollutants and further solutes must also be quantified by methods that allow for calibrations.
