A novel application of modified bamboo charcoal to treat oil-containing wastewater and its modified mechanism

by IWA Publishing  (Dec. 19, 2014)

Three conventional coalescence filters including walnut shells (WS), polystyrene resin particles (PR), and quartz sand (QS) were compared with bamboo charcoal (BC) to treat oily wastewater in a coalescence system process. The results showed the order of oil removal efficiency was QS>BC>WS>PR. To improve the oil removal ...

Magnets: A viable alternative to flotation for sand producers

by Eriez Magnetics Europe Ltd  (Dec. 17, 2014)

Introduction The basic rudiments of mineral beneficiation have not changed for many years. The techniques have been improved, but are still essentially the same, using either a materials weight, density, shape or magnetic susceptibility to enable separation. For removing impurities from non-metallic minerals, such as silica sand, typical methods ...
