Ovivo signs exclusive licensing agreement with District of Columbia Water and Sewer Authority


Ovivo, a global provider of water treatment equipment, technology and systems, has signed an exclusive licensing arrangement with the District of Columbia Water and Sewer Authority (DC Water) for its patented post-aerobic digestion process. 

The process is marketed under the brand nameDigestivorePAD.

This approach to solids management places an aerobic digester after an anaerobic digester, thereby providing increased volatile solids destruction, enhanced nitrogen and phosphorus removal as well as improved dewatering, leading to significant operational savings.

The DigestivorePAD technology will tap DC Water's years of collaborative research and innovation on this concept as well as Ovivo's decades of experience with sludge stabilisation at high solids concentrations using both anaerobic and aerobic digestion.

Ovivo is owned by SKion Water International GmbH and Caisse de dépôt et placement du Québec.

It operates in over 15 countries and has around 800 employees.
