... the biofilm and therefore overcome the inactive zones of bacteria. To test this hypothesis, four experiments have been performed in an EMB with toluene as a model pollutant. The effect of excess and low nitrate concentrations on biofilm formation and toluene flux has been investigated. At lo ...

... seems to comply with such requirements. The objective of this work was to apply dense polymer membranes to pervaporative separation of toluene from wastewaters. The investigation studies involved the tests on composite membranes made up from polydimethylsiloxane (PDMS) as well a ...

Applying filled and unfilled polyether-block-amide membranes to separation of toluene from wastewaters by pervaporation
... pervaporation membranes mostly tree types of fillers have been used: zeolite, silicate and carbon sieve. This study focused on the removal of toluene from the wastewaters. The concentration of that solvent in the feed solution was close to its solubility in water — 500 ppm. The tests wer ...
