Properties of Reverse Osmosis Water
The purpose of a reverse osmosis desalination system is to remove a large percentage of
the dissolved minerals (salt) in sea or brackish water. Systems operating within
specification typically will remove at least 98% of the "salt" in seawater, generating product
water with mineral content of less than 750 parts per million.
The reverse osmosis process used in the Aqua-Pac can be highly effective at removing
bacteria and other pathogens from the feed-water. The degree of effectiveness depends
upon such factors as the age and condition of the semi-permeable membrane and on the
concentrations and types of pathogens contained in the feed-water.
The product water from an RO desalination system is typically fed to storage tanks of
unknown sterility where it may sit, stagnant, for weeks at a time before being used.
Compounding the problem, storage tanks are sometimes filled by sources other than the
RO system.
If the water in the storage tanks is to be used for human consumption, Balmar
recommends that steps be taken to ensure that the water does not contain unsafe levels
of pathogens.
One method is to chlorinate the water in the storage tanks. Chlorine tablets and chlorine
injection systems are available to treat drinking water. If the water is to be chlorinated,
follow the manufacturer's directions precisely.
Chlorinating unfortunately does not remove any objectionable tastes or odors that the
water may have absorbed in the storage tanks. The chlorine will actually add taste and
odor to the water. Also, the chlorine may react unpredictably with any chemicals, which
may have gotten into the tank.
Balmar offers various post-filters and an ultra-violet sterilizer/ charcoal filter to treat the
water before it goes into the water tank and as it comes out of the water tank. Contact your
dealer for more information.
Watermaker Installation
Pay particular attention to how the exhaust system will be routed from the engine. Keep in
mind that the exhaust tube will probably have to rise higher than the engine so that no
water can enter the engine from the outside.
Central Processor Module Mounting
The CPM (Control Panel) may be either surface mounted or through a cutout in a bulkhead.
Locate a suitable mounting place for the CPM. In order to obtain accurate readings from
the product flow meter, the CPM must be mounted vertically.
