The Purposes Of Using ROWPU 3000 Water Treatment Unit

By Michelle Cook


An RO or a reverse osmosis is a purifying technology. A semi permeable membrane is being used in order to remove some ions, molecules, and other larger particles from drinking waters. An applied pressure is also being used in order to overcome the osmotic pressure or the colligative property being driven by the chemical differences of the solvent.

Reverse osmosis is also used in most industrial processes and as well as in producing potable water. And as a result, the solute will be retained on the membrane side which is pressurized and the solvent will pass to the other side. The membrane only allows the smaller components to pass, such as the solvent molecules. The main use of reverse osmosis purification unit or ROWPU 3000 water treatment unit is for the military use.

There are already a lot of drinking purification systems in the world today and the reverse osmosis is one of those. Some steps used in these systems include sediment filters, second sediment filters, activated carbon filters, second carbon filters, and ultraviolet lamps. Separating pure waters from brackish waters and seawaters is one of the most important applications for osmosis.

The membranes that are utilized in osmosis are containing dense layers in its polymer matrix where the separation occurs. Membranes are mostly designed only for allowing the water to pass through the dense layers and not allowing the solutes to pass like the ions. This process of osmosis is known for its desalination or the separation of salt from seawaters, thus, producing fresh waters.

The 3000 gallon ROWPU is mainly utilized by the militaries or armies for water purification. The process helps in the treatment of waters from being brackish or being fresh, and being contaminated. The system is stationed within an ISO container of 8 x 8 x 20 feet. The container is mounted on the military trailer of 30 feet. Its source of power is a generator having 60 kilowatts and found at the back of the trailer.

The system was designed in order to purify 3,000 gallons in 77 degrees Fahrenheit temperature in just one hour. Turbidity is one factor that would more likely affect the rate of production. The system also has the capability to remove effectively any concentration of the chemicals, agents, and radioactive of nuclear origin products which may be hazardous.

The ways on the treatment process are the following. First, raw systems draw water from its source through course screens. Raw pumps are then filled with it and is turned on, and it pulls the air from suction hoses and it also pulls the water up from pumps. So to pull it up quickly, a hand operated prime may be used.

To prime initially, a hand pump or can is used. Using hand pumps may only take 2 to 3 minutes for lifting through the hose sections, if not, it will take 6 to 8 minutes. If the pump is already primed, the suction and as well as the check valves help in preventing it to run back down to the source when stopping the pump.

The pressure of the raw pump will then deliver it to the separators wherein it will be swirled in high speed to be able to throw the dirt and sand outside through waste hoses. When it passes in the separators, it is delivered to the ROWPU van where the booster pump suction feeds the pressurized water to infiltration components.
