Wabaseemoong retrofits RBCs into MBBR
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.
