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 energy
consumption of selected water and wastewater
treatment 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 Analysis
and Water Quality Correlations;
Energy Consumption Auditing; and,
Identifying Potential Energy Saving
Features. Several EC analysis examples are given including Arizona American Water (Anthem): MBR, involving challenges that included: the amount of time required
to assist in the study;
would like to do both Drinking Water and
Wastewater membrane systems, or none at all; and,
one of the SES supports equipment for both water
and wastewater facility. Cauley Creek, GA: MBR where the staff indicated not much the plant can do to further
reduce energy consumption without potentially
violating system warranties or permit. Pooler, GA: MBR where there was only one power reading for the entire facility, and had a
constant 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 current
transformers (CT) installed;
each CT has a local readout but the information is
not recorded by the SCADA; and,
MF/RO monitoring will exclude Phase IV to avoid
interfering 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 treatment
technologies for regulatory compliance as
well as tapping into alternative water sources;
ATT usually uses more energy;
this project develops an Energy Analysis
Framework; and,
this project evaluates true EC for 6 ATTs. Includes figures.
