Selectors were operated at four full-scale activated sludge plants to control bulking and foaming problems due to filamentous microorganisms. Selector effectiveness was not related to reduction of biodegradable organic matter in the contact zone, but was related to soluble COD levels in selector effluent. Significant reductions in the numbers of filamentous m icroorganisms were reported.
在四座全尺寸活性污泥处理厂中设置了选择器，以控制丝状微生物导致的污泥膨胀和泡沫问题。选择器的有效性与接触区可生物降解有机物的减少无关，而是与选择器出水的可溶性化学需氧量（COD）水平有关。据报道，丝状微生物数量显著减少。
