scientific disposal of toilet waste in the non-sewered areas, Faecal Sludge Management (or 'FSM') emerges as the imperative option. FSM is to ensure that liquid waste from human settlements is adequately con-tained, transported, and treated before final disposal or re-use. FSM as a process may be thought as three
Tungsten carbide sludge, is also known as swarf, powder, or dust. It is a byproduct from the grinding, cutting, shaping, and forming of the manufacturing of tungsten carbide tooling, inserts and wear parts and other carbide items. We accept carbide sludge that contains a minimum of 50% tungsten with a cobalt binder.

The next step in the recycling strategy of the grinding sludge is to separate the grinding swarf from the abrasives. For this separation, a dry screening (Retsch AS 200 control) was used to divide the grinding sludge into seven fractions. The used mesh widths were 1000 μm, 500 μm, 250 μm, 63 μm, 45 μm.

Sludge drying bed (SDB) is the most widely used method for sludge dewatering. Sludge drying involves natural ways of drying to mechanical ways of removing water content. SDB is generally used for small and medium sized communities (TCHOBANOGLOUS et al. 2003). The selection of the technology will depend upon land availability, climatic …
Grinding sludge is a solid waste formed at automobile parts manufacturing industries. This sludge contains fine metal chips and oil based coolant. According to solid waste management rules (2016), the sludge containing oil has to be handled by government …
Characteristics of industrial sludge vary greatly. It may contain biodegradable, non-biodegradable, toxic compounds, heavy metals, etc. The sludge may be in the form of liquid or semisolid with 0.25–12% solids. Thus, the handling and disposal/reuse of sludge may become a complex task due to its large volume and …
Different petroleum operations produce huge amount of oil sludge annually.
