These U.S. Military Mobile Desalination Systems are in the original crates and packaging.
--------------------------------------------------------------------------------
Capabilities and Features:
Produces drinking water from contaminated sources at a rate of 150,000 gallons per day.
Skid-mounted for ease of transport by land, sea, or air.
Open air design allows easy maintenance of equipment.
Total feed water flow: 347 GPM. Product water flow: 104 GPM. Total brine concentrated flow: 243 GPM.
Note: Actual performance of this equipment will vary with changes in environment, operating conditions, condition of reverse osmosis membranes, and the salinity of the raw water being processed.
--------------------------------------------------------------------------------
Booster Pump Assembly and Hose: Pumps water to the pre-treatment assembly; Booster Pump Engine is a three cylinder Diesel Engine which drives the booster pump through a belt-driven speed increaser.

Pre-treatment Assembly: Consists of a Control Box that includes 12 volt electrical circuitry for input power, controls, indicators and the chemical metering pumps; a Coagulant Aid and Metering Pump, short stroke, piston-diaphragm dosing pump with an adjustable amount of coagulant aid to feed water stream; a Scale Inhibitor Metering Pump that is the same type as the coagulant aid / metering pump and provides an adjustable amount of scale inhibitor to the feedwater stream; Cartridge Filter that will contain 12 filter elements which remove matter that escapes the multimedia filters.
Multimedia Filter: Intended to filter water and pass it back to pre-treatment assembly.
High Pressure Pump and Assembly: Pumps water from the pre-treatment assembly to reverse osmosis assembly, boosting water pressure to high level required for reverse osmosis. Powered by a six cylinder diesel engine which drives high pressure pump through a matched set of 12 V-belts.
Reverse Osmosis Block Assembly: Consists of 16 pressure tubes, each tube designed to contain five reverse osmosis membrane elements, that filter the water through the reverse osmosis process.
The offered equipment includes the Booster Pump, the Pre-treatment Skid Assembly; the Multimedia Filter, the High Pressure Pump, the Reverse Osmosis Block, and Membranes and Filters originally issued with this equipment by the military.
