Salmon Arm council is learning more about filtration technology and odour concerns at the city’s sewage treatment plant.
Engineering director Jennifer Wilson spoke with council about filtration technology as a possible treatment process at the city’s Water Pollution Control Centre.
A staff report said a membrane bioreactor with biological nutrient removal (MBR-BNR) has been selected as the preferred secondary treatment process for the Water Pollution Control Centre Stage 5 upgrade.
The report said developing three options to a comparable conceptual level allowed staff to conduct an informed and defensible assessment of the preferred technology and help ensure fair market value for any proprietary technology selected.
Three technologies were developed and evaluated: conventional activated sludge, aerobic granular sludge and membrane bioreactor.
“MBR effluent is the cleanest and most consistent of the technologies helping protect the natural environment of Shuswap Lake and continue the City’s legacy of excellent stewardship,” the report stated.
Salmon Arm Mayor Alan Harrison raised concerns about odour from the facility and said MBR technology is the preferred option because it addresses environmental impacts to Shuswap Lake and odour issues.
