The Power Of Bundling: BIOSTYR® + ACTIFLO®

In 1998, Onondaga County signed an Amended Consent Judgment with the State of New York to significantly increase the level of treatment at its Metropolitan Syracuse Wastewater Treatment Plant (Metro). Since then, the addition of North America’s largest biological aerated filter system (BIOSTYR®) and the largest tertiary ballasted settling system (ACTIFLO®) in the U.S. has allowed the Metro plant to consistently meet very low effluent ammonia and phosphorus limits. The bundling of Kruger’s BIOSTYR and ACTIFLO processes into a combined solution has played a key role in the markedly improved water quality conditions in Onondaga Lake.

The Metro plant is next to Onondaga Lake, and the length of pilings (275-feet) required for construction dictated that the new facilities be as small in size as possible. The Kruger technologies selected for the Metro plant have the smallest footprints of any commercially available alternative and, through extensive competitive trials, were shown to provide the lowest operational costs possible for the high level of post-secondary treatment required.
