History of BIOSOR®

Two case studiesBIC (1997): 15 employee-siteKipawa (2001): 600 inhabitants

Communal approach


What is BIOSOR® ?

“BIOfiltration sur Support Organic” = organic support biofiltrationAerobic (low pressure air injected)Fix media with a support structure:

peat + wood chips + other organic ingredientsGradient of filtration (patented non clogging multi layer approach)Ideal for:

High organic loads (manure)or

High hydraulic loads (group of houses, small municipalities, etc.)Completely passive operation and low maintenance systemQuebec government pre-approval for commercial / communal / institutional (third party verification in 2000)French government pre-approval for manure treatment (third party verification in 2001)


WHAT IS HAPPENING?

FiltrationAbsorptionAdsorptionCation exchangeCarbon biodegradation (BOD5 removal)Nitrification (NH4 NO3)Denitrification (NO3 N2)

Why no biological sludge disposal? →Equilibrium almost obtained between growth and death of bacteria→The biomass accumulates very slowly, and mineralization occurs

BIOSOR® : appreciated for reliability and low operation/maintenance

OperationWeekly verifications of alarms logs on peripherals (pumps and blowers) (can be remotely monitored)

Regular maintenanceWater distribution maintenance (1 to 2 times/year = 1 to 3 hours)Pumps and blower normal manufacturer maintenance (easy access)

Long term maintenanceMedia renewal partial or total (every 5 to 7 years)

“Very little maintenance is required”“It is not expensive to operate; the holding tanks must be pumped out

occasionally”“We monitor the system, Health Canada

also does additional monitoring to ensure we are respecting the

environmental discharge criteria for sewage discharge and we continue to

meet the targets”Lance Haymond, Chief of Eagle Village,

BIOSOR®: as a communal system

Qualities of BIOSOR :Simplicity • No operator system (passive system)• Only weekly check ups by a non specialized employeeLittle maintenance, no heavy equipment • One submersible pump and one blower (1 to 3 HP)–outside the system• Only maintenance on the distribution system - clean-up -2 times per year (couple

of hours)• Remote monitoringRobust -Stable• Accepts variations in load and flow• Non clogging distribution system• Absorbs chocks and interruption operation • Gravity feed is possibleLow community impact• Visually pleasing, no building (only a service shed)• Secure, odourless, Quiet• Economic
