  • Viscous heating effect on deactivation of helminth eggs in ventilated improved pit sludge

    Viscous heating by extrusion of faecal material obtained from ventilated improved pit (VIP) latrines can be used to deactivate soil-transmitted helminth (STH) eggs by increasing the temperature of faecal sludge uniformly. Viscous heating can deactivate STH eggs present in sludge to make the material safer to transport, dispose of, or use in agricultural applications or as an energy source. The ...

  • In-situ stabilization using Shallow Soil Mixing and Deep Soil Mixing

    Of the currently emerging technologies for site remediation, one of the most attractive and economical is in-situ stabilization and/or in-situ fixation of contaminated soils by Shallow Soil Mixing (SSM) or Deep Soil Mixing (DSM). Actually, the soil mixing process is not new. It has been in use as a geotechnical construction process for over two decades. However, its use as a treatment for ...

  • Structural Monitoring Inside a Copper Mine

    CAS DataLoggers recently supplied the intelligent datalogging solution for the operators of a copper mine. For the safety of both miners and machinery, it was essential that any potentially dangerous situations were identified early by closely monitoring the mine’s entire structure to detect ground movement or subsidence around the mine which could make the structure become unstable. A ...
