RBF PYROBIOMETHANE PROJECT
BLOOMINGTON, CA
The PyroBioMethane Project is an expansion of the existing Rialto
Bioenergy Facility (RBF). The term “Pyrolysis” is described as the
thermal decomposition of organic matter at elevated temperatures
(350-750 °C) in an inert atmosphere. The existing RBF plant
currently receives 300 tons per day of WWTP biosolids which is
conveyed through a dryer system that converts the biosolids into
a dry granulate material that can be used as a Class A fertilizer.
With the addition of the Pyrolysis system, the process is extended
by sending the dried granulate Class A fertilizer to a 2-stage
pyrolyzer furnace where it is converted into a carbon-rich biochar
with high nutrient content suitable for direct land application for soil
regeneration.
The perfectly executed setting of the Thermal
Oxidizer Tower at the Rialto Bioenergy Facility
1 week of prep and mobilization of the cranes prior to the pick. The
pick itself took approximately 45 minutes to complete and was very
anti-climactic (in a good way). Then another week to demobilize the
crane and crane mat off-site. The pick itself went almost as perfect
as possible which was a testament to the entire team for all of the
upfront planning and effort that was put into the task. This project
was a HUGE success - congratulations to all!!!

On June 16th, the project team (WML, TNG and Hill Crane)
successfully rigged, hoisted and set the Thermal Oxidizer (TO)
Tower onto its foundation. Although not identified as a contractual
milestone, this was a significant event for the project and the project
team. The rigging and setting of the TO Tower was identified as the
highest risk on the project from the very beginning. The TO Tower
is 72 ft tall and weighs approximately 230,000 lbs. This tower was
delivered to site in 3 sections and had to be assembled onsite in the
horizontal position. After assembly, the tower needed to be picked
up and up-righted into the vertical position and then set onto its
foundation. WML worked with TNG and Hill Crane to coordinate
this critical pick which required an engineered lift plan signed and
stamped by a CA licensed professional engineer. The 300-ton
crawler crane that was used for this pick had to be assembled
onsite and was delivered on a total of 22 trucks. There was about
RP-4 PRIMARY CLARIFIER AND PROCESS
REHABILITATION PROJECT
Rancho Cucamonga, CA. The Letter of Substantial Completion
for the RP-4 Primary Clarifier and Process Rehabilitation Project
was received on September 8th, 2022. The original contract
consisted of concrete rehabilitation/coating at the existing Influent
Pump Station (IPS), Grit Chambers (GCs), and Primary Clarifiers,
equipment rehabilitation at the Primary and Secondary Clarifiers,
new grit equipment for Grit Chamber No. 2, rehabilitation of the
Lagoon Recovery Pump Station, and a new Secondary Scum
Pump Station. One of the more difficult aspects of the project was
the requirement to keep the plant fully operational during the entire
construction phase. In order to achieve this, the entire influent
flow had to bypass structures where work was taking place.
Bypasses were installed for the Lagoon Recovery Pump Station
rehabilitation and for the concrete rehabilitation/coating at the IPS
3
and GCs, requiring 24/7 monitoring. Through coordination and
teamwork with IEUA, WML was able to simplify the bypass and
reduce the risks involved while ensuring a successful operation.
The success of the project was owed in large part to the great
relationship between WML and the IEUA project management
team and plant staff, who worked together towards a common goal
of having a positive outcome for the IEUA and their clients. A huge
thank you to all WML and IEUA staff members who contributed to
the collaborative success of this project.
