The use of marine sponges dates back thousands years, and interest in these animals is increasing as new applications are discovered. Their potential extensive, both their ancient still popular bath for cosmetics regarding the more recent discovery bioactive secondary metabolites mainly pharmaceutical industry less developed aquariology. Despite proven biofiltration ecosystem restoration abilit...

Delhi, the capital city of India is facing many problems of water shortage which are exacerbated by the population growth, urbanization, industrialization and migration. As part of the WP 7.9 of the TECHNEAU integrated project, the feasibility of the OBM process combined with river bank filtration to provide a sustainable and safe drinking water supply for Delhi is investigated within this repo...

The intentional use of the vegetative growth of mushroom-forming fungi on wood mulch substrates as a biologically active filtration media, a process known as mycofiltration, is a promising new technology for enhancing biofiltration of stormwater, graywater, and agricultural runoff. Recent trials have documented that Escherichia coli can be selectively removed from contaminated water approximate...

Biochemical processes by chemoautotrophs such as nitrifiers and sulfide and iron oxidizers are used extensively in wastewater treatment. The research described in this dissertation involved the study of two selected biological processes utilized in wastewater treatment mediated by chemoautotrophic bacteria: nitrification (biological removal of ammonia and nitrogen) and hydrogen sulfide (H2S) re...

A biofiltration process was used for degradation of vinyl chloride as a hazardous material in the air stream. Three biotrickling filters in series-parallel allowing uniform feed and moisture distribution all over the bed were used. Granular activated carbon mixed with compost was employed as carrier bed. The biological culture consisted of mixture of activated sludge from PVC wastewater treatme...
