Full Description

East Cherry Creek Valley Water verify performance for pre-selected RO membranes;evaluate fouling and scaling potential of Beebe Draw well water;evaluate process pretreatment requirements;provide RO system orientation for ECCV staff; and,determine acceptable blend of RO permeate water with raw well water toachieve taste and odor goals for distribution system water. Key criteria investigated include pretreatment requirements (antiscalantselection and acid feed requirements), operating pressures and productivity measured by mass transfercoefficient (MTC, gfd/psi), rejection performance, blend water quality, and concentrate water quality.Membranes were operated at a high product water recovery of 85% throughout the study. The ECCV ROpilot study used Beebe Draw groundwater from an existing well in Lochbuie, Colorado. This site waschosen for the RO pilot study because the well provides a reliable water supply with water quality typicalof the Beebe Draw aquifer. ECCV is evaluating potential well sites that will be in proximity to the wellwith similar water quality characteristics. Includes 4 references, tables, figures.
