Anaerobic Selectors: Effective Control of Biological Processes
Innovative anaerobic mixing for effective EBPR
Anaerobic selectors encourage biological treatment for removal and recovery of phosphorus from wastewater streams to protect the environment and promote sustainable practices for finite resources. Enhanced biological phosphorus removal (EBPR) utilizes anaerobic fermentation to maximize the biological uptake of phosphorus by phosphorus-accumulating organisms (PAOs).
While the actual uptake of phosphorus occurs in an aerobic environment, PAOs must first be conditioned by exposure to volatile fatty acids (VFAs) in an anaerobic environment.
BioMix-DC Enhanced Anaerobic Mixing optimizes the anaerobic fermentation process by alternating a short mixing cycle with a long deep cycle. This allows stratification in the reactor, increasing the solids retention time in that zone and resulting in the formation of additional VFAs.
A BioMix™ Compressed Gas Mixing System can be used alone or in combination with BioMix-DC to provide mixing in an anaerobic environment.
Additionally, the BioCycle-ENR Activated Sludge Process is ideally suited for municipal and industrial secondary treatment processes that include anaerobic selectors.
