Workshop Memorandum 18-057
Date: February 13, 2018
From: Kevin Lee, Interim Operations Manager
Thaxton VanBelle, Interim Operations Manager
Subject: Overview of Proposal for Rehabilitation of Belt Press #1 and #2 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 20 years
and has proven to be a simple and
reliable technology that has been easy
to maintain with a long useful life.
As this equipment has surpassed its
useful life the District staff has noticed
signs of metal fatigue and stress cracks
in the equipment. Both belt presses
were rehabilitated 15 years ago, in
2003, proving that this method can
extend the life cycle as long as the main
frame of the belt press remains in good
condition. It was confirmed by Alfa Laval at the time of the evaluation that the main frame was
indeed in good condition.
District staff recommends the rehabilitation as quoted with adding supplemental items #1 and #2.
