The Processes Made In ROWPU 3000 Water Treatment Unit

By Michelle Cook


A reverse osmosis or RO is a technology that is used for purifying. It uses a membrane which is semi permeable for removing the molecules, ions, and some other larger particles from the drinking water. It also uses an applied pressure for overcoming any osmotic pressure which is a colligative property driven by some chemical differences of 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 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 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.

The system was produced for the purification of that 3000 gallons inside a seventy seven degree Fahrenheit in one hour. Turbidity is one of the elements that affects the production rate. The system is also capable of removing any concentration from chemicals and agents, and as well as the radioactive product origin that may possibly be hazardous.

So here are the ways on how this treatment unit is being processed. First is the raw system draws it from the source through a course screen. The raw pump will then be filled and it is turned on, pulling air from the suction hose and pulling it up from the pump as well. So for it to be pulled up quickly, a prime which is hand operated must 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.
