Biological processes

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

The research herein builds on the work of Rojek (2003) and further investigates the bioremediation of NOM wastes. The aim of this research was to evaluate the effectiveness of selected white-rot fungi and yeast for the biodegradative removal of concentrated NOM from solution. The effectiveness of the white-rot fungus P. chrysosporium ATCC 34541 for the biological degradation of different batches of MIEXTM NOM concentrate and the effects of different characteristics of the NOM on the process and thus the resistance of the NOM to microbial removal were investigated.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.
