... ABSTRACT: Sludge exerts a very big environmental load to local sea area. Here, attention was paid to micro-bubble technology for application to the purification of sludge. The important point in this technique is to activate the bacteria existing in the area by micro-bubbles. In this study...

... ABSTRACT Stone sludge is produced in the process of cutting and grinding of stones. Because stone sludge contains a lot of silica, it is thought that mixing the stone sludge expedites the pozzolanic reaction of cement. In this study, we mixed irrigation pond sludge with stone sludge and cement...

... ABSTRACT A solidification method by cement of dredged sludge has been performed in laboratory during last four years. The treated sludge is partially contaminated by some heavy metals. The objectives of the research program was to treat and reuse the solidified sludge as road or civil...

... the dirty and hard labour work, we made up a new concept of further simplified total waste oil treatment system, and also at the first stage developed the water and sludge separating unit which is the prime equipment for this new system. This unit is so designed as to be capable of continuously separating...

... ABSTRACT The effects of municipal (sewage) sludge and crude oil on physical and mechanical properties of laboratory prepared marine clays were investigated. Contaminants appeared to influence the development of clay microstructure and thus some of the physical and mechanical properties...
