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.

This technology is also being used mostly in the production of potable water and also in some industrial processes. The result for this is that the solute is retained to the side of membrane being pressurized and solvent passes to another side. Membranes will only allow the passage of smaller components like solvent molecules. ROWPU 3000 water treatment unit or reverse osmosis purification unit is mainly used for military purposes.

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 utilized membranes in a process of osmosis have dense layers in the polymer matrix. The polymer matrix is where the separating process will occur. The membranes are usually designed only to allow the waters in passing through dense layers and will not allow solutes to pass such as the ions. This osmosis process became more popular because of salt separation from the seawaters. This process is called desalination.

The 3000 gallons of ROWPU is being used by armies as a water purifier. This type may treat any contamination, or it may be brackish or fresh. This system is placed inside an ISO container with a size of 8 x 8 x 20 feet and is mounted on a 30 feet military trailer. Its power source is mounted at the rear part of the trailer with a 60 kilowatts generator.

This system is designed for purifying 3000 gallons in a 77 degree Fahrenheit for only one hour. One of the factors that will most likely affect the production rate is turbidity. This system has also the capability of effectively removing concentration from the agents, chemicals, and nuclear radioactive origin of products that are 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.

For initial priming, a can or hand pump will be used. By the use of hand pumps, lifting it through hose sections will only take two to three minutes, and if not, it takes six to eight minutes when lifting. When the pump is primed already, suctions and check valves will prevent it from running back down to its source.

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.
