The Kentucky American Water (KAW) Kentucky River Station II Water Treatment Plant is a new 20 MGD conventional turbidity removal facility located near Owenton, KY. The plant’s water supply, the Kentucky River, experiences a wide range of turbidity fluctuation from very low, single-digit NTU’s to extremely high turbidities in excess of 2,000 NTU.

As part of the engineering design team, GRW designed the residuals dewatering building which receives sludge from the plant residuals thickeners.  Our scope of work included the sizing and selection of the VFD-controlled progressive cavity sludge feed pumps which are installed in the piping gallery of the residuals thickener in order to transfer the thickened sludge to the belt filter process located in the residuals dewatering building. The polymer storage facility included a 6,350 gallon sloped bottom bulk storage tank with a progressive cavity recirculation pump for keeping the tank well mixed. The polymer delivery system includes three polymer feed units, with each unit consisting of mixing chamber, dilution water controls, neat polymer pump, and system controls. Each polymer feed unit was dedicated to a specific belt filter press.

GRW also designed the 3,900 SF residuals dewatering building to include belt filter presses, pressed sludge conveyor, polymer storage and delivery, climate controlled operator’s office, and an electrical room. The residuals dewatering building was designed to house three belt filter presses; the conveyor collects pressed sludge cake continuously from the discharge of each press and transports it from the building to be deposited in a dump truck stationed in a covered external storage area attached to the side of the building.
