sensitive to rain water flow. because of the high allowable volumetric load the footprint of the gsbr variants is only 25% compared to the references. however, the gsbr with only primary treatment cannot meet the present effluent standards for municipal wastewater, mainly because of exceeding the suspended solids effluent standard caused by washout of not well settleable biomass. full scale application aerobic granulation technology is already successfully applied for treatment of wastewater. since 2005, royalhaskoningdhv has implemented more than 20 full-scale aerobic granular sludge technology systems (nereda) for the treatment of both industrial and municipal wastewater across 3 continents. one example is stp epe, the netherlands, with a capacity of 59.000 pe and 1,500 m3.h-1, being the first full-scale municipal nereda in the netherlands. examples of the latest nereda sewage treatment plants (2012–2013) include wemmershoek- south africa, dinxperlo, vroomshoop, garmerwolde – the netherlands. full-scale municipal sewage nereda application (4000 m3.d-1) at the gansbaai stp in south africa full-scale municipal sewage nereda application epe the netherlands full-scale industrial sewage nereda application vika the netherlands ecoengineering applied aerobic granulation process in three pharmaceutical industries, krka d.d. novo mesto slovenia, lek d.d. lendava, slovenia and gedeon richter rt. dorog, hungary. wastewater treatment plants are already running more than five years.
