Full Description

This slide presentation outlines AwwaRF Project #3051: Evaluation of the Dynamic Energy Consumption of Advanced Water and Wastewater Treatment Technologies. Project objectives included: quantifying actual and theoretical energyconsumption of selected water and wastewatertreatment technologies;evaluating factors affecting energy consumption (EC); and,identifying energy optimization opportunities. A list of participating utilities and technologies is provided, along with steps to developing energy analysis framework that include:Information Collection;Theoretical Energy Efficiency Analysisand Water Quality Correlations;Energy Consumption Auditing; and,Identifying Potential Energy SavingFeatures. Several EC analysis examples are given including Arizona American Water (Anthem): MBR, involving challenges that included: the amount of time requiredto assist in the study;would like to do both Drinking Water andWastewater membrane systems, or none at all; and,one of the SES supports equipment for both waterand wastewater facility. Cauley Creek, GA: MBR where the staff indicated not much the plant can do to furtherreduce energy consumption without potentiallyviolating system warranties or permit. Pooler, GA: MBR where there was only one power reading for the entire facility, and had aconstant flow rate, near constant water quality. Seward, NB: reverse osmosis (RO) where the challenge was its remote location (3 hr drive from Omaha). West Basin: MF, UV, RO where energy monitoring included:the individual RO and MF processes have currenttransformers (CT) installed;each CT has a local readout but the information isnot recorded by the SCADA; and,MF/RO monitoring will exclude Phase IV to avoidinterfering construction; Phase IV UV will be available. Three more EC analysis examples are outlined, and a summary of observations included: more utilities are using advanced treatmenttechnologies for regulatory compliance aswell as tapping into alternative water sources;ATT usually uses more energy;this project develops an Energy AnalysisFramework; and,this project evaluates true EC for 6 ATTs. Includes figures.
