7. DISCUSSION and BACKGROUND
The existing 350kw emergency generator at the Marywood Pump Station has a maintenance
issue with its current diesel particulate filter system. In order for the existing filter system to
clean itself, the generator has to run under enough load to heat up the generator and burn off the
diesel particulate collected in the filter. If the particulate filter does not clean itself, the alarm
system will trigger and prevent the generator from running. During the weekly maintenance
cycle, the generator runs for approximately 30 minutes under load from the pump station. The
duration and frequency of maintenance cycle for this emergency generator is dictated by the
AQMD permit requirement. These operating conditions do not allow enough time and load for
the generator to generate enough heat to clean the existing particulate filter system.
An effective solution to this issue is to replace the existing filter system with an active
regenerative diesel particulate filter system called RYPOS. This innovative filter system will
draw power directly from the generator to burn off the particulates collected inside the filter and
continue to do so when the generator is running with or without load. The RYPOS filter system
is being used on the new generator recently installed at Well 27. It eliminated the need to rent
costly equipment during the generator maintenance cycles. The scope of work includes removal
of the existing filter system, installation of the new RYPOS active regenerative filter system,
testing and commissioning the new system on -site.
Staff contacted Kohler, Generac, Caterpillar, and Bay City Electric Works for quotes. Only Bay
City Electric Works has responded with a written quote. Bay City Electric Works is the current
generator maintenance service provider for the City of Orange. They have the expertise and
knowledge of the RYPOS filter system. Therefore, staff is requesting the approval to purchase
and install the RYPOS filter system from Bay City Electric Works in an amount not to exceed
$59,659.
