biofiltration method is one of the most commonly used and most effective methods to removepollutants from the exhaust gas flow from different industries. one of the most important categories of airpollutants is hap (hazardous air pollutants). this study assesses the ability of biofiltration method toremove and treat hap dea (diethanolamine) from a gas stream through a laboratory-scale biofilter...

Microorganisms accumulated in these cracks and might have contaminated cleaning equipment even when it had been disinfected. A plastic hose helped reduce the problem. Flushing the hose for several minutes before filling cleaning equipment also controlled the risk of dissemination. Both P aei-ugiizom and Emerobacter cloacae were recovered from the inner areas of the rubber hose. Hospital infecti...

There is a continuous attempt at seeking different, economical and environmental-friendly means of improving the strength soils. This work therefore studied effects shredded plastic waste (SPW) on selected To achieve aim study, lateritic soil samples were collected from two identified active borrow pits in Ile-Ife. Following standard procedures, following tests conducted soils their natural sta...

Polyvinyl chloride (PVC) is made by polymerizing vinyl chloride monomer and is a plastic that softens on heating. The addition of a small amount (<5%) of plasticizer produces a hard PVC, whereas the addition of 30 to 50% plasticizer results in a soft PVC. Soft PVC is used to make several products, including chemical shoes, cables, gloves, hoses, and film. The principal component of PVC hose is ...

There is considerable interest today in the so-called “biocell” approach toward municipal solid waste (MSW) landfilling in which leachate is introduced back into the landfill. This approach reduces the cost of leachate management and is said to reduce/eliminate the potential for long term landfill gas production and groundwater pollution. However, a critical review of the typical approach being...
