Wall deflection induced by pre-excavation dewatering under different construction conditions
Yantu gongcheng xuebao, 2017 The existing field measurements show that the deformation of retaining wall and surrounding environment induced by pre-excavation dewatering can reach centimeter level, but the relevant researches are still less.

Correlation between dewatering index and dewatering performance of three mechanical dewatering devices [PDF]
Advances in Environmental Research, 2003 Abstract Efficient sludge conditioning can improve sludge dewatering characteristics and promote the separation of flocs from the liquid phase to achieve a high solid content. To optimize this process, a reliable dewatering index must be established.

Sewage Sludge Electro-Dewatering [PDF]
, 2011 Original sludge from wastewater treatment plants (WWTPs) usually has a poor dewaterability. Conventionally, mechanical dewatering methods are used to increase the dry solids (DS) content of the sludge.

Effects of ultrasonic duration on performance of sludge dewatering
Yantu gongcheng xuebao, 2023 Sludge flocs tightly wrapping a large amount of bound water results in poor performance of sludge dewatering. The ultrasonic treatment is one of the effective methods to improve performance of sludge dewatering.
