Ovivo has signed an exclusive licensing arrangement with DC Water for the utility’s post-aerobic digestion process. Marketed under the brand DigestivorePAD, this approach places an aerobic digester after an anaerobic digester, providing increased volatile solids destruction, enhanced nitrogen and phosphorus removal, and improved dewatering. The technology will combine DC Water’s years of collaborative research and open innovation with Ovivo’s experience in sludge stabilization at high solids concentrations using anaerobic and aerobic digestion.
