The plant upgrades included the addition of a new SLB 848 preliminary screening system to enhance solids and biological removal for treatment improvements. The addition of a new 15,500 gal (40m3) Polyethylene EQ tank located outside to provide a buffer for incoming flows, and allow equalization of peak hour flows. Aeration provided with duplex air compressors from within the building, with a loss of air alarm provided back to the Programmable Logic Controller (PLC). Time dosed duplex pumps will operate on a Time On – Time Off sequence which is adjustable at the main Programmable Logic Controller (PLC) to allow flows to equalize over the 24-hour period.
