The Ovivo system included a pre‐ piped, pre‐wired and pre‐tested equipment skid, which greatly reduced on‐site installation hours.
DESCRIPTION
Located in the North‐Central Wisconsin, the Stockbridge‐Munsee Community is a Band of the Mohican Tribe with over 1,500 members. As the tribal facilities continued to expand and with construction of the North Star Mohican Casino and Hotel already underway, the Stockbridge‐Munsee Community turned to Ovivo's MBR technology to upgrade and expand their aging recirculating sand filter treatment system. As good neighbors in the community and a strong desire to protect the environment, tribal leaders also required any new treatment technology to meet all State and Federal effluent standards for groundwater discharge including a stringent limit on Total Nitrogen of 10 mg/l.
