Caviness Beef Packers selects Yardney Water Management
Systems to Design and Fabricate a 1,250 gpm Water Treatment
System for the Removal of Iron (Fe) and Manganese (Mn)
This beef processing plant located in Hereford, TX was having significant issues with the
use of the water from the city due to the high levels of iron (Fe) and manganese (Mn).
This resulted in higher than expected plant operating costs.
Yardney Water Management Systems of Riverside, CA (Yardney), designed a turnkey
system using DMI-65, a revolutionary new filtration media manufactured by Quantum
Filtration Medium in Western Australia. DMI-65 is a silica sand based filtration media
that will remove iron, manganese and arsenic when operated in the presence of chlorine
System Design and Fabrication
Yardney has over 40 years of experience in system design and vessel fabrication and
has provided many different types of systems for all types of applications. One of the
main advantages of the vessels produced by Yardney is the ability to utilize many
different types of specialty medias without having to make significant modifications to the
vessel design. The result is additional technical and economic benefits realized for the
The client requested a completely automatic system that would provide a constant flow
of 1,250 gpm. This requirement was an ideal application since it allowed for one of the
many standard designs offered by Yardney to be utilized. The system utilized a total of
sixteen 54" diameter x 60" side shell, fusion epoxy lined, carbon steel vessels.
Yardney has determined, from many years of experience and hundreds of system
installations, that this diameter of vessel provides a high degree of flexibility and ease of
operation when dealing with applications requiring constant or variable flows. This size
vessel is also more cost effective than using larger diameter vessels and can achieve a
complete backwash within 4-6 minutes while requiring less water during the backwash
System Automation and Operation
The client’s main desire was to have a system that would be effective in removing the
iron contaminant, but also require little operator involvement with regards to operation
and maintenance. With this in mind, Yardney proposed an automatic system with a
control package utilizing a free chlorine residual monitor and metering chemical pump.
The chlorine-metering pump also receives a signal from the free chlorine residual
monitor, which then controls the chlorine-metering pump. The result is that the proper
hypochlorite feed and free chlorine residuals are monitored and maintained without
operator attention regardless of the service flow through the treatment system.
The system was installed and commissioned in October 2011. Since start-up, the quality
of the water being supplied by the Yardney system utilizing the specialty iron removal
media has met and exceeded the client’s expectations. This has allowed the plant to use
the city water treated by the Yardney system throughout the plant. Additionally, they
have found other uses in the plant due to the high quality of the water produced. In
terms of cost savings, the client is realizing over $6,000/week on filter bag and cartridge
filter savings since the installation and start-up of the treatment system.
