Key West Resort Utilities Maximizes Reuse And Nutrient Recovery
Water scarcity poses unique challenges to KW Resort Utilities Corp. (KWRU), the utility firm that provides wastewater management, wastewater recovery, and wastewater treatment in the region. KWRU began operation in the late 1960s and has worked hard over the decades to keep up with wastewater needs as population and tourism have boomed, spurred by land reclamation and development.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing
With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Optimizing Air Flows To Aeration Basins
As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.
