|Toelichting (Engels)||Over the past few years, struvite has caused scaling problems in pumps, pipes and dewatering facilities of the sludge line at WWTP West (Waternet). A process called ‘AirPrex’ is available for the controlled formation and removal of struvite directly from the digested sludge. It is claimed that the AirPrex process is not only effectively preventing scaling problems, but is also improving the sludge dewaterability. On top of that, the recovered struvite can be used as a phosphate fertilizer.|
