This plant is somewhat unusual because the normal design flow is quite low but a few times a year, when the College has significant events, the daily flow will increase significantly. Rather than design the plant for these occasional peak flows, the plant was designed with a larger-than-normal aerated flow equalization tank. This plant is installed indoors, in a maintenance garage building.
Because of the potential for hydrocarbon contamination or other non-domestic wastes in the sewage stream, this plant was built utilizing the cMBR "SaniBrane®" ceramic membranes. The ceramic membranes are nearly indestructible and can be cleaned with high back-pressure, hot water and strong chemicals without damage.
