In this study, the authors developed a simulation model to evaluate the life-cycle cost (LCC) and life-cycle CO2 (LCCO2) in a municipal solid waste (MSW) management system by taking into account the construction/renewal and maintenance patterns of MSW treatment facilities from mid or long term perspective.

The objections of residents over the construction and operation of waste incineration facilities has strongly influenced waste management practices in Seoul, Korea. It was found that people's impressions depended on their perception of associated risks as well as the information provided by the government.

The performance of various aeration systems for treatment of two different industrial liquid effluents was performed and discussed in this work. Fixed, combined and diffused systems were chosen. The samples for different detention time were tested for BOD and COD, before and after aeration for these three systems.

The ability of weathered coal to remove Cr(VI), Hg(VI), Hg(II), Cu(II) and Fe(II) from aqueous solution by adsorption was studied. In this work, adsorption of heavy metals on weathered coal has been studied by using batch techniques.

Removal of chromium (III) from aqueous solution by microbial waste biomass (MB1) obtained as a byproduct of pharmaceutical fermentation industry was studied. In order to understand the sorption kinetic behaviour of chromium (III), a series of batch mode experiments were conducted at different pH values, adsorbent dosage and initial chromium concentration.

Environmental pollution has become a cause for great concern as it continues to increase rapidly day by day. The heavy metals, such as copper, lead, chromium and nickel are more toxic to the living organisms. In the present investigation, an attempt is made to remove the heavy metals using activated carbon of rice husk.

In this study activated carbon from corncob, an agro waste was used as an adsorbent for removal of malachite green and methyl violet from aqueous solutions. Parameters, such as adsorbent dosage, concentration of the dye, contact time and temperature were optimized with regard to the dye removal using the selected adsorbent.
