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.

Nowadays, there are a lot of systems for drinking purifications are already used and one if it is the reverse osmosis. Ultraviolet lamp, activated carbon filter, sediment filter, second carbon filter, and second sediment filter are some steps that are used in processing. The separation of pure waters from salty waters can be one important process involved in 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.

So the following are the ways for the treatment process. First, a raw system will be drawing water from source through using course screens. A raw pump will be filled with it, it is switched on and will start on pulling the air from suction hose while pulling up the water as well from pump. Hand operated primes are suggested to be able to pull it quickly.

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.
