Specifications

Pressure Regulator
The Pressure Regulator consists of a manual pressure regulator and a pressure gauge
mounted on the control panel. The regulator maintains the proper back pressure on the
membrane.
Control Panel
The Control Panel permits operation and monitoring of the system from a convenient
location such as in the living quarter of a boat.
Feedwater Pump
The Pre-feed pump consists of a separate relay controlled pump that forces feed-water
through the pre-filters. Installation of a feed-water pump will decrease pre-filter
maintenance, system noise and vibration and RO pressure pump wear. If either the engine
or the Pre-Filtration Module must be mounted more than two feet above the feed-water
source level, a Feed-water Pump Module will be required as well as a check valve. A Feed-
water Pump Module is recommended for all installations.
Emulsion Removal Module (ERM) Optional
This unit removes oil or silt from the feed-water, to further protect the RO membrane. This
element should be replaced as soon as oil is detected or every year during normal
servicing.
Plankton Filter Assembly Optional
This is a 50-micron SS element that works more efficiently than the sea strainer and never
needs to be replaced -- just cleaned on a normal basis. This will not replace a sea strainer.
Ultraviolet/Charcoal Sterilizer Optional
Although the RO process is very effective at removing bacteria and other pathogens from
the feed water, a UV/Charcoal Sterilizer can be added that will function as a second line of
defense against any micro-organisms that may have penetrated the RO membrane. The UV
Sterilizer is recommended anytime the desalinator is going to be used in brackish or
sewage contaminated waters. The charcoal element removes foul odors and tastes in the
product water. The charcoal filter is rated at .5 micron and should be replaced every year.
It is a special style charcoal filter, call Balmar for replacement. The UV bulb should be
replaced every 2000 hrs. or every two years. After recommended replacement time, the
spectrum of the light will shift and cause insufficient radiation of the bacteria and viruses.
Supplemental Filters
A 5 micron filter is standard with the Aqua-Pac. 5 and10 micron filters are available in the
standard size. Larger surface area filters are also available in various micron sizes. Media
filters are available for land based or commercial applications.
Freshwater Flush Assembly Optional
This is a charcoal filter and three-way valve assembly designed to be installed onto the
fresh water system for flushing the salt water out of the desalinator. Not intended for long
shut down periods. Up to one month before re-flushing is required.
