sludge particles meaning in Chinese

残渣微粒
淤渣颗粒

The higher the sludge concentration and the flux were , the easier it was for the sludge particles to deposit on the membrane surface
污泥浓度愈高，膜通量愈大时，活性污泥颗粒愈易在膜面沉积。
It was found that soluble organic substances were adsorbed on the membrane surface at the early stage of membrane fouling , then the sludge particles deposited on it
结果表明，膜污染初期主要是水中溶解性物质在膜表面附著，随后污泥在膜表面沉积。
Soluble organic foulants contributed little but sludge particles deposited on the membrane surface resulted in a rapid increase of the transmembrane pressure
溶解性有机物在膜面的附著，对膜过滤压差即膜过滤阻力的变化影响不大，而活性污泥在膜表面的大量沉积将导致膜过滤压差迅速上升。
