ACE for Activated Sludge


World Water Works Selected by DC Water to Bring Their Patent-pending AVN Technology to the Global Activated Sludge Market

World Water Works Inc. has been selected by the District of Columbia Water and Sewer Authority (DC Water) and the Hampton Roads Sanitation District (HRSD) to bring their patent-pending AVN technology to the global market.

The technology, which is named for the balance it achieves in ammonia oxidizing bacteria (AOB) vs. nitrite oxidizing bacteria (NOB), utilizes a proprietary control strategy, applying selective pressure to aid in the segregation of the desired bacterial populations. This allows wastewater treatment systems to achieve more efficient removal of total nitrogen.

AVN will deliver a return on investment to customers by managing the influent carbon, minimizing the alkalinity demands and reducing the energy requirement of the system while maintaining superior effluent quality. AVN is the ACE (alkalinity, carbon, energy) solution for removing ammonia in the mainstream treatment activated sludge process.
