Katadyn Survivor 35 Manual Desalinator
 

Katadyn Survivor 35 Desalinator
Katadyn's patented Energy Recovery System In the 1980s, the US Navy identified the need for a portable, hand-operated desalinator to provide emergency fresh water for sailors and downed pilots. We responded with an innovative solution that made it possible: The Energy Recovery System or water maker

In order to remove dissolved salts from seawater with a reverse osmosis membrane, extremely high pressures must be generated. Traditionally, powerful motors and large amounts of energy were used to generate the necessary pressures. This was no problem for large vessels that had plenty of power and space to spare. Therefore, fresh water was a luxury that few sailors could afford.

The Katadyn Energy Recovery system takes advantage of stored energy in the high pressure reject water that is typically wasted. The pressurized reject water is recirculated to the back side of the piston to aid the next stroke. This energy is kept in the system, resulting in less work to achieve fresh water.

With this unique technology, we were able to develop the first, and only, manual desalinators (water maker) in the world. The same technology that allowed efficient hand operation was adapted to higher output power units to give energy-efficient cruisers access to the "luxury" of fresh water on demand. Today, water makers have almost become standard equipment, and Katadyn leads the way with the most energy efficient solutions.
REVERSE OSMOSIS 
In reverse osmosis, part of the salt water is filtered through a semi-permeable 
membrane. Only 10% of the water passes through the filter membrane. The 
remaining 90% flows past the membrane and at the same time cleans the 
membrane (self-cleaning effect). The small size of the membrane pores ensu-
res extremely pure drinking water, but makes extremely high pressure neces-
sary - normally 55 bar. 
Reverse osmosis is used - in this form or similar forms - worldwide to obtain 
drinking water, e.g. in the semi-conductor industry and in medicine.
