Degradation of organic compounds of anthropogenic origin in retentates after ultrafiltration and reverse osmosis in a two-stage ozonolysis and photolysis
Real retentates from the treated wastewater were studied for content of total, org. and inorg. C, total N, PhOH index and absorbance at 254 nm. Samples were taken after 30 min exposure to O-3 and after 15, 30, 60, and 120 min long irrdn. with UV. A decrease in total C content, PhOH index and absorbance was obsd. The combination of ozonolysis and photolysis resulted in increasing the effectiveness of wastewater treatment.
