Ovivo MBR technology has provided the Tribe with reclaimed wastewater, with which to irrigate and help beautify lands.
DESCRIPTION
The MBR facility replaced a poorly operating activated sludge system at the site. Frequent complaints of odors from the facility, problems with drainfield clogging and failure and expensive operation and maintenance all led the Tribe to look at alternative treatment systems. The major drivers for technology selection were an extremely fast-track schedule, small footprint, expandability, ease of operations and high-quality effluent, all of which are hallmarks of the Enviroquip MBR process.
