Ozone Water Treatment and Advanced Oxidation

Municipal Drinking Water - Ozone has been shown to be effective in a variety of drinking water applications including: disinfection, color removal, iron (Fe) and manganese (Mn) reduction, hydrogen sulfide removal, taste and odor reduction micro pollutant removal and improved filtration and flocculation of potable water. Ozone can also reduce formation of disinfection by-products such as trihalomethanes and haloacetic acids. Ozonation is effective for removal of difficult-to-treat pathogens such as giardia and cryptosporidium. To learn more about ozone generators in municipal drinking water applications click here.

Industrial Wastewater Treatment - Ozone and advanced oxidation processes can selectively remove pollutants from industrial wastewater and process water, e.g. TOC, COD, BOD, cyanide, phenol, color among many other compounds. This can include discharge to surface waters or to POTW (referred to as pretreatment). Ozone can also be used to keeps sumps clean and odor free.

Ground Water Remediation – Ozone and ozone based advanced oxidation processes can be used for ground water remediation. It can be applied via in-situ chemical oxidation (ISCO) methods or by pump and treat methods (link to Ozone Pump and Treat for Ground Water). Ozone based technologies have been used successfully to treat various DCE, TCE, 1,4 Dioxane, BTEX and other common groundwater contaminants.

Odor Control and Removal - Ozone can be used for sewage odor control and wastewater odor control by oxidizingcontaminants from air at municipal and industrial plants. To learn more about ozone generators and ozone odor controlapplications click here.

Cooling Water Treatment - Ozone has been used extensively for treatment in cooling water towers. It is a powerful and environmentally friendly oxidizing biocide. To learn more about ozone generators in cooling water treatment click here.

Rainwater Harvesting - Ozone and UV can be used to treat water produced from rainwater harvesting application. Combined with filtration these technologies can safely treat the rainwater for many applications such as toilet flushing and landscape irrigation.

Food and Beverage Applications - Ozone generators are used a variety of applications for food and beverage processing. For example, ozone is the dominant method for the treatment of bottled water. It is also used the processing of fruits and vegetables. To learn more about ozone and ozone generators for food and beverage processing click here.

Aquaculture - Ozone is used to treat feed water as well as improve water quality in aquaculture systems including recircualting aquaculture systems (RAS). To learn more about ozone use in aquaculture follow this link discussing ozone generators and ozone water treatment in RAS.

Municipal Wastewater Treatment - Ozone has been used in two applications for municipal wastewater treatment: disinfection of wastewater effluent prior to discharge and treatment of sludge from the activated sludge process. In the latter case the sludge treatment can reduce the amount of excess sludge and minimize the phenomenon known as bulking. More recently, ozone is being considered for water ruse applications to recycle municipal wastewater for a variety of applications including indirect potable use.

Gas Phase Surface Disinfection - Ozone can also be used to disinfect surfaces in the gas phase. This approach might offer a better option that using aqueous phase ozone for surface treatment. Due to the high gas phase concentrations, the treatment must be done in a closed space.
