Industrial Water & Wastewater

Man is a complex being: he makes deserts bloom – and lakes die. — Gil Scott-heron (1949-2011)

The effectiveness of ozone technology in the industrial marketplace and the continued discovery of new applications in the industry, has contributed to the advancement of ozone generation technology.  Typical industrial applications include the following:

Industrial Wastewater

Industrial wastewater often contains complex toxic compounds that are difficult to degrade.  Ozone is an effective, fast-acting oxidizer of a wide variety contaminants including sulfides, pharmaceuticals and personal care products.

An effective application for ozone is the stabilization and reduction of wastewater sludge in industrial treatment plants.  Sludge is often hauled and disposed of at landfills; this process is costly.  Unlike oxidants such as hydrogen peroxide, ozone penetrates the cell wall (lysis), degrading bacteria that can then be consumed by other bacteria.  This process can reduce wastewater sludge by 50%-60%.

Additional benefits achieved by ozonation include foam reduction, oxidation of odors, improved clarity and a dramatic reduction in filamentous bacteria.

Industrial wastewater treatment plants are required to monitor COD and BOD levels to insure the treated water discharge meets EPA standards.

Ozone treatment is an effective method of reducing COD and BOD in industrial wastewater.

Bottled Water

Virtually all bottled water manufacturers incorporate ozone into their treatment train to improve shelf-life and to produce the most desirable taste and clarity for their product. Unlike other disinfectants, ozone decomposes to oxygen and does not produce unwanted tastes and odors.  The FDA recognizes ozone treatment of bottled water as a Good Manufacturing Practice


The textile manufacturing process is a major source of global environmental pollution.  Textile wastewater often contain dissolved organic dye compounds that are considered carcinogenic.  The legal requirements concerning discharge of contaminated wastewater are enforced in many countries, and the discharge fees continue to increase.

According to our experience large clothing companies are setting a new standard of requirements, often higher than the local legislation requires.

When dye is dissolved into process water, it contains surfactants and other additives that are made up of organic compounds with complex structures.  These compounds are resistant to light, oxygen and acids, as they are desired properties of dyed textile.

With high concentrations of ozone, it is possible to break down harmful dissolved organic dye compounds and reduce the amount of color and enhancing the biodegradability of the wastewater. The combination of filtration, biological chemistry, and ozone has proven effective for textile wastewater treatment.
