AOX

Around the world, companies are striving to protect our waterways and land while continuing to do business. High levels of AOX in wastewater are a sign of pollution. This is a serious environmental problem, but Desotec has the solution.

The standard method to estimate the level of AOX entails measuring the amount of chlorine, bromine, and iodine that are adsorbed in activated carbon. This offers you a hint of how effective Desotec’s filters are.

Most AOX are chlorinated, including dichloromethane (DCM), trichloroethylene (TCE), pesticides, trichloromethane (chloroform), chlorophenols, and chlorobenzene. Some AOX components are biodegradable, but others are not. Among these are Persistent Organic Pollutants (POPs), including polychlorinated biphenyls (PCBs) and dioxins.

Desotec’s sustainable mobile filter technology removes all of these components, leaving wastewater clean for discharge or reuse.

Reducing AOX in wastewater is essential before discharge to preserve waterways and soil quality. Because some AOX components are toxic, our filtration protects aquatic life and human health.

Desotec filters also reduce non-biodegradable components (POPs) to very low levels. POPs pose a particular challenge: they accumulate in nature, where they can enter the human food chain and imply risks to our health.

If your company is seeking ways to tackle AOX and POPs, Desotec is here to help. Our mobile activated carbon filtration solutions are effective and sustainable purification treatments for wastewater, groundwater, and process waters in any industry.

The Water Framework Directive is the overarching water legislation at EU level.

Many countries are also tightening their own regulations governing AOX treatment. In France, for example, the legislative order of 15 February 2016 (l’Arrêté du 15 février 2016) relating to non-hazardous waste storage facilities means that, in the coming years, wastewater containing AOX must be pretreated before it can be sent to a wastewater treatment plant (WWTP).

Local environmental authorities typically set very low AOX limits for site operating licenses, due to the harm they can cause.

Desotec has the expertise and the technology to ensure that your company can meet stringent AOX limits.
