From: Kevin King, Operations Manager
Subject: Overview of the Dewatering Equipment Pilot Testing Study at the Wochholz
Regional Water Recycling Facility
The Wochholz Regional Water
Recycling Facility uses belt filters to
remove liquids from the biosolids
collected throughout the sewer
treatment process. The belt filter
technology has been in use at the
sewer treatment plant for over twenty
years and have proven to be a simple
and reliable technology that has been
easy to maintain with a long life. As this
equipment has surpassed its useful life,
the District staff has noticed signs of
metal fatigue and stress cracks in the
equipment. Therefore, we have started
to process to evaluate other available
technology to plan for the replacement
of the existing belt presses.
The District staff has tested alternative
dewatering equipment to further reduce maintenance, energy and hauling costs. Pilot testing of
potential equipment provided an opportunity to validate the equipment performance and provide
the operations staff members with first-hand knowledge about the overall operation and
maintenance of the equipment.
This presentation outlines the methodology and process used for determining the most cost
effective method for replacing the existing equipment.
