The black and odorous water body treatment projects promoted the application of various engineering solutions but also produced large quantity of solid waste, like the ultra-magnetic sludge (UMS) which is the river suspensions thickened and discharged by ultra-magnetic separator. Characterized by high concentration of water content, organic matter and compact structure, the dewatering of UMS will greatly benefit transportation and further use. In this study, the mechanical dewatering methods were tested and combined onsite in order to reduce the water content of UMS to 42~48%. The operating parameters and effects were discussed while the indexes of resultant UMS was analyzed shows promising use as land improvement agent.
