The Processes Made In 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 many drinking purification systems today which are widely used and reverse osmosis is considered one of the steps used. Some steps used are sediment filters, activated carbon filters, second sediment filters, second carbon filters, and the ultraviolet lamp. Separating the pure waters from the brackish waters is one important application of 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.

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 raw pump pressure delivers it to separators where it is swirled in fast speed. This is done in order to throw away the sand and dirt through the waste hoses. If it passes in separators, it will be delivered to ROWPU vans and the booster pump suctions will feed the pressurized waters to the infiltration components.
