Non-biodegradable Wastewater

Wastewater from industry, businesses or agriculture, that contains chemical pollution, which is toxic for microorganisms and can therefore not be treated by biological wastewater treatment units. In order to degrade the toxic chemicals, other processes such as advanced oxidation processes (AOP) need to be applied. Often, it is possible to degrade first the toxics with AOPs after which the wastewater becomes biodegradable and can be treated as municipal wastewater. This can reduce costs, as generally AOPs require more technical know-how and energy.
