De Nora receives second DTRI approval for treating potable water with chlorine dioxide

High-efficiency vacuum-based CIO2 generators validated to 97% yield.

Continuing to shape the future of water treatment in the Middle East, De Nora announced its latest approval from the Desalination Technology Research Institute (DTRI), a division of Saudi Arabia’s Saline Water Conversion Corporation (SWCC), for its vacuum-based Capital Controls chlorine dioxide generators. Tested by DTRI as part of the certification process consistently demonstrated a yield of 95% to 97%, a ratio representing high-efficiency production of chlorine dioxide, De Nora claimed.

This marks the second approval of De Nora chlorine dioxide generation technology by DTRI. In September 2019, the underwater technology by De Nora ISIA was also approved with a yield of up to 98% following the same process.

Dr Mirka Wilderer, CEO of De Nora Water Technologies, commented: “Since bringing ISIA under the De Nora umbrella of Capital Controls disinfection technologies, our capabilities with chlorine dioxide have excelled, which is extremely important in areas with advanced treatment needs. Chlorine dioxide has proven to be highly effective at treating water while also limiting by-products associated with desalination processes, such as bromate.

“We believe our technology will help providers like SWCC continue advancing their capabilities, which, in turn, will make a positive impact on other water-stressed communities around the world looking to the region’s desalination pioneers fur guidance.”

De Nora vacuum chlorine dioxide generators currently range in capacity from 0.5kg per hour to 20kg and offer a mobile 20ft container. De Nora Capital Controls chlorine dioxide generators’ advantage is its high-efficiency rating. By operating at a 97% yield, the system requires less chemicals, saving costs and water.

The DTRI approval comes on the heels of several announcements in the region. De Nora has been underway in finalising a localised office in Saudi Arabia and will also help host the International Specialty Conference on Innovation in Desalination taking place this May. The company will also participate in what is dubbed the “world’s largest” green hydrogen production plant being constructed along the shores of the Red Sea, awarded an alkaline water electrolysis contract by Thyssenkrupp Uhde Chlorine Engineers (NUCERA) last December.

“We’ve taken a heightened focus on the Middle East to support local leaders as they navigate the most severe water shortage in recorded history. We hope together with partners throughout the region, our efforts will pave the way for others around the globe also dealing with the effects of climate change. This is only the tip of what we expect to be a much larger iceberg,” Dr Wilderer concluded.
