Manganese (Mn) is one of the most abundant metals in Earth’s crust. Manganese is present in ground water as a divalent ion (Mn2+) and is considered a pollutant mainly because of its organoleptic properties. It is an essential metal for the human system and many enzymes are activated by manganese. Therefore, manganese has to be removed from some waters and wastewaters for various reasons. Conventional chemical and physical treatments for Mn(II) removal from contaminated effluent consist of precipitation, depth filtration, ion exchange, adsorption and oxidation. The adsorption technique has been found to be one of the most effective for the …


Ground Improvement With Special Reference To Non-Toxic Chemical Stabilisation And Deep Sub-Surface Drainage, Buddhima Indraratna, Jayan Sylaja J S Vinod, Cholachat Rujikiatkamjorn Jan 2012

Ground Improvement With Special Reference To Non-Toxic Chemical Stabilisation And Deep Sub-Surface Drainage, Buddhima Indraratna, Jayan Sylaja J S Vinod, Cholachat Rujikiatkamjorn

In this paper, two advanced ground improvement schemes have been introduced to improve soft and erodible soil properties. The improvement of an unstable formation soil with pH neutral chemical admixture and the sub-surface drainage is described. Internal erosional behaviour of lignosulfonate treated erodible soils has been studied using the Process Simulation Apparatus for Internal Crack Erosion (PSAICE) designed and built at UoW. Effectiveness of lignosulfonate treated erodible soils on the erosion resistance has been investigated and its advantage over conventional methods are presented and discussed. For soft soil formation stabilised by sub-surface drainage, the paper will look at the inevitable …

Coke Oven Emissions: A Case Study Of Technology-Based Regulation, John D. Graham, David R. Holtgrave Jun 1990

Coke Oven Emissions: A Case Study Of Technology-Based Regulation, John D. Graham, David R. Holtgrave

RISK: Health, Safety & Environment (1990-2002)

After examining and analyzing the experience with coke ovens, the authors conclude that attempts to force technology beyond its demonstrated competence can be both expensive and ineffective in controlling hazards. They also suggest implications for pending proposals to further control air pollution.
