Biodegradable Systems

Increases the efficiency of aerobic and anaerobic biodegradation systems. 

In many full-scale applications the variable costs for energy and oxygen are regarded as economically decisive. Ozone and cost savings have often been achieved by the application of combined ozonation/biodegradation systems. Today, in most cases, ozonation of waste... 

Kuo [198] studied the effect of O3/UV on the toxicity and biodegradability of an industrial pesticide wastewater. He observed increases of BOD/ COD ratio up to a value of 0.4 with more than 50% reduction in toxicity (measured as EC50) when using 400 g m-3 h-1 of ozone and 3 mW cm 2 of UV light intensity. The author also recommended the use of the integrated 03/UV-aerobic biodegradation system for scale-up purposes.

The solvent should be readily available from a local supplier and be cost-effective for pilot- and/or industrial scale [7]. The solubility of the pollutant in question in the diluent should be as high as possible to allow maximum pollutant loadings in the two-phase partitioning bioreactor system, that is, make the biodegradation system perform most effectively [1]. As the last criterion, the diluent should not form emulsion with the treated wastewater. This is required to minimize the entrainment of the cells of the MO used in the organic phase of the system, potentially leading to decrease in the rate of biodegradation [12].
