Reduce SBR Maintenance Costs With Jet Aeration
6/16/2017
Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing
9/18/2017
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.

Pile Cloth Media Filtration For Clean Utilities
4/15/2019
Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.
