Consultant will review existing raw water quality evaluated under Work Order #17, and <br />utilize available data to define, if necessary, the design raw water quality to be used for <br />membrane projections. A design and worst case list of raw water quality parameters will <br />be used for membrane projections. <br />Consultant will conduct up to twenty (20) membrane projections using membrane <br />suppliers' software, with up to three (3) different membrane element manufacturer, and <br />evaluate if optimization of the membrane system with respect to recovery, array, and <br />other operating parameters are warranted to improve operating efficiency and lower <br />operating pressures. Consultant will review membrane suppliers that can manufacture <br />membrane elements which meet Hobart's treatment system requirements. <br />Consultant will develop a matrix of improvements that includes capital costs, operating <br />cost savings, priorities (1 — 5 years), and how they are dovetailed into the wellfield and <br />SCADA system improvements.
