AbstractThe paper is a review of the results obtained in our laboratories from the study on the mechanism and technology of combined electron-beam and biological purification of industrial wastewater from non-biodegradable hard surfactants. They are a mixture of isomeric isobutylnaphthalene sulfonates which is known as nekal and is utilized as an emulsifier in the production of synthetic rubber, for example, at the Voronezh plant in Russia. The electron irradiation is used for the conversion of nekal to biodegradable products by the removal of alkyl or sulfonate groups from the molecule (with the formation of naphthalene sulfonate, alkyl naphthalenes and naphthalene). Different experimental techniques were applied to elucidate the mechanism of the respective radiation-induced processes. For example, it was found by pulse radiolysis that

Stimulation Of

The artificial stimulation of biological purification of sea-pollutant hydrocarbons requires phosphorus supply. The concentrations, corresponding to the optimal bacterial growth, depend, in particular, on ionic strength. They range between 2 and 8 × 10−4 M for waters in which the salinity is close to the mean salinity of an oceanic environment and between 1.5 and 3 × 10−3 M when these waters receive a significant supply of freshwater or when salinity is naturally weak. Inhibition of bacterial development has been observed either with a microflora, or with pure strains for concentrations higher than the upper limits of concentrations so defined.

Microporous membranes have been developed which can remove endotoxins selectively from electrolyte and albumin solutions by regioselective adsorption in the membrane matrix and outside surface of the membrane. The membranes were prepared in the form of hollow fibre membranes in a continuous process. By varying the membrane preparation parameters, different pore sizes and adsorption capacities could be realized, thus broadening applications for biological purification. Dynamic adsorption capacities for endotoxin from albumin and saline solution were determined and were found to be in the range of 0.2 and 0.1 μg endotoxin/g membrane, respectively, suggesting different adsorption mechanisms.
