Multi-criteria decision analysis for the optimal management of nitrate contamination of aquifers

Article Abstract:

An integrated methodology is presented for the optimal management of nitrate contamination of ground water combining environmental assessment and economic cost evaluation through multi-criteria decision analysis. The results showed the importance of using the integrated approach, which predicts the sustainable on-ground nitrogen loadings and provides an insight into the economic consequences generated in satisfying the environmental constraints.

Upflow column reactor design for dechlorination of chlorinated pulping wastes by Penicillium camemberti

Article Abstract:

A Penicillium camemberti strain isolated in the laboratory is studied for its ability to degrade chlorinated pulping wastes, presumably containing a variety of chlorinated polyphenols. The results showed that the continuous upflow packed bed reactor containing glass wool-immobilized fungus P. camemberti removed 61% of the color, 65% of total organic carbon (TOC) and 76% of the chlorinated organics from chlorinated pulping effluents.

Combined chemical and biological oxidation of penicillin formulation effluent

Article Abstract:

The chemical treatability of penicillin formulation effluent bearing the active substances penicillin Amoxicillin Trihydrate and the beta-lactamase inhibitor Potassium Clavulanate is investigated in a study. The results obtained via combined chemical and biological oxidation of penicillin formulation effluent indicate that advanced oxidation is reasonably suited and quite feasible for application as a pre-treatment method.
