4” x 40” Ultra Filter System Operator Manual
PRODUCT DESCRIPTION
The Ultra Filter System uses 4” x40” spiral wound polysulfone elements that are enclosed in
special vessels to process RO/DI water at a required minimum and provides an extremely high
recovery rate.
This device is not intended for any other application. The filtration process is similar to a Reverse
Osmosis machine, however this device has no pump attached and is equipped with a 3 valve by-
pass.
This device works from system water pressure, with a small amount of waste or reject water
going to drain. The output (
product
) water from the filtration system is affected by other
components in the water treatment system which affect, pressure, temperature and flow-rate.
Ultra filter membranes are a consumable product. The life of the membrane is directly related to
the monitoring and routine care programs that you maintain in your facility. With proper care,
monitoring, and disinfection, the life of the spiral wound membranes can be prolonged for several
years.
An Ultra Filter system, in conjunction with good disinfecting programs, is a very effective means
of controlling bacteria and endotoxins in the post treatment and distribution segments of a water
purification system.
