When the rotating biological contactors at Wabaseemoong Independent Nations in northwestern Ontario experienced “catastrophic failures” and the existing RBCs couldn’t be replaced (because the building had been built around them), a new solution was going to be required.
J.R. Cousins Engineering turned to Nexom transform the remote first nation’s RBC basins—complete with challenging sloping sidewalls—into an easy-to-operate, efficient, reliable BioPorts™ moving bed biofilm reactor (MBBR). This cost-effective system retrofit charts a course for future RBC sites to meet future treatment needs.
