The CO P catalytic oxidation system is a complete prefabricated unit used to treat wastewater contaminated with volatile organic compounds (VOCs) and high biological oxygen demand and chemical oxygen demand. The system uses ozone, ultraviolet light, and hydrogen peroxide to create hydroxyl radicals used in oxidation. [Pg.921]

Ozonolysis can be applied for assessing the pollution level of potable and wastewaters, by determining the ozone demand in an apparatus including an ozone generator and UVD for measuring the amount of O3 supplied. A correlation can be established between the ozone demand and the chemical oxygen demand, which is a standard method for pollution evaluation. The advantage of the ozonolysis route is its speed (a few minutes for sample... [Pg.739]

Regression analysis in time series analysis is a very useful technique if an explanatory variable is available. Explanatory variables may be any variables with a deterministic relationship to the time series. VAN STRATEN and KOUWENHOVEN [1991] describe the dependence of dissolved oxygen on solar radiation, photosynthesis, and the respiration rate of a lake and make predictions about the oxygen concentration. STOCK [1981] uses the temperature, biological oxygen demand, and the ammonia concentration to describe the oxygen content in the river Rhine. A trend analysis of ozone data was demonstrated by TIAO et al. [1986]. [Pg.219]

Anaerobic biodegradability of 2,4-dinitro-phenol using phenol-supplemented cultures is induced by ozone. Ozonization removes chemical oxygen demand (COD) by 80%. The ozonization product is effectively biodegraded to methane (Wang et al. 1989). [Pg.823]

Ozone is generated on demand from oxygen and ozone storage is not required. The amount of ozone produced is varied in response to the amount of NOx sys-... [Pg.343]

Handhng ozonides even in small amounts demands special care. Thus, various ozonides can be innocuously synthesized, by passing ozone-enriched oxygen through dry solutions of the corresponding olefins at —78 °C, followed by low-pressure distillation below 60 to 70 For example, the FOZs of methylenecyclohexene and methylenecyclopentene... [Pg.718]
