Sewage is increasingly contaminated with xenobiotics of all sorts, from human waste to antibiotics, products and by-products produced by industry.
Sewage treatment systems can´t handle all of these contaminants. This is the reason why municipal wastewater is the major source of xenobiotics in the aquatic environment. Conventional biological treatment based on activated sludge, is not efficient enough to remove those trace pollutants. Therefore, more enhanced technologies, such as ozonation, have to be implemented to
achieve sufficient results in removal of these substances and may be crucial for the future.
This study investigates implementation of ozonation step for effluent of a municipal WWTP (Waste Water Treatment Plant). In laboratory scale, different types of ozone measurement were examined: amperometric, spectrometric,
titration with KI solution and `test kit´ - quick test. Different concentrations, from 1 to 10 mg/l of ozone, were applied. Removal of organic compounds was investigated by controlling TOC (Total Organic Carbon) and BOD (Biochemical Oxygen Demand). Vital point for this investigation was to use received results for pilot plant scale in order to be applicable on municipal WWTP.
Main assumptions of the project (on both laboratory and pilot plant scale) were color, odor and organic compounds removal.
