Effective removal of 1,4-Dioxane from industrial wastewater

In chemical processes, the very toxic substance dioxane can be generated. UV-AOP Technology prevents this substance from ending up in nature and eventually drinking water by supporting the chemical industry with a sustainable and innovative advanced oxidation technology.

Removal of dioxane from industrial wastewater.

Treatment of industrial wastewater

A company in the Netherlands encountered the issue that their on-site wastewater treatment could not remove 1,4-dioxane, resulting in outgoing concentrations exceeding local regulations. The permitted maximum outgoing concentration was <1 mg/L, requiring a removal efficiency of >92% to meet discharge limits.

Reduced invironmental impact

Very effective removal of 1,4-dioxane with advanced oxidation technology.

Energy savings

By optimizing the dosage of UV-C light and hydrogen peroxide, the energy waste of the AOP installation is minimal, consuming 0.70 kWh/m3.

Stricter EU regulations regarding dioxane

Companies in the chemical industry are facing stricter EU regulations regarding dioxane, a common by-product of chemical processes. This is a positive development because dioxane is persistent and toxic, can easily spread in water, and is carcinogenic. 1,4-Dioxane is often found in cosmetic products, formed unintentionally as a by-product in the production process.  To prevent dioxane from entering nature and even our groundwater, reliable removal is necessary. This poses a challenge for companies to develop robust water treatment methods that mitigate risks and avoid downtime.

UV Solution:

UV advanced oxidation reactor to purify water from dioxane. It combines UV-C light and (sustainable) hydrogen peroxide, reacting with the contamination and ‘burning’ it in the water, breaking it down into harmless particles.

UV Results:

UValue Creation:
  • Environmental impact: because AOP is an intensive treatment, the treatment is extremely effective.
  • No chemicals: any residual hydrogen peroxide is not a problem for the subsequent wastewater treatment plant, in other applications it can be easily removed with minimal impact on treatment costs.
