Low power ultrasound can modify sludge bulking characteristics, improve sludge settling and dewatering properties, so decrease sludge water content and sludge volume.

小功率超声波能够改善污泥的膨胀特性、提高污泥沉淀特性和脱水能力、降低污泥的含水率，达到减量的目的。

High density sludge process can decrease the volume of sludge to be disposed of by over 90%, therefore considerably reduce the cost of sludge disposal.

高密度污泥水处理工艺可使污泥生成量减少到十分之一左右，极大地减轻了污泥处理的负担；
