The reverse osmosis water dispenser has been developed in the past few years to provide homes and other private institutions reliable methods to acquire clean water for human use and consumption. The device follows a series of procedures and uses different tools that cleanse water effectively by removing known contaminants that are invisible to the naked eye.
RO Main Components
A whole house reverse osmosis water dispenser is usually made up of 4 major components namely the pre-treatment equipment, the reverse osmosis unit, the storage tank and the re-pressurization system. The pre-treatment equipment may not be required depending on the quality and source of water.
Before reverse osmosis or RO treatment, excess mineral hardness should be removed from the water to keep the membrane from fouling prematurely. Water softeners, activated carbon filters or anti-scalant injections work best for this since the membrane deteriorates quickly upon making contact with chlorine.
Storage and Water Supply
Ther reverse osmosis unit is used to produce the water requirements of a household everyday. About 20 gallons of purified water per hour is produced by a 500-gallon-per-day system. A supplementary storage system is required to provide more water as needed if 20 gallons are not enough to supply household function demands.
The storage tank is atmospheric or non-pressurized to provide enough water for daily activities. As water is taken from the tank, the reverse osmosis unit refills it with more. The re-pressurization system is made of a simple pump that automatically turns on and provides pressurized water whenever it is required. A smaller bladder or diaphragm tank filled to the house pressure via a pump provides more water during periods of high demand.
When Choosing a System
When considering a reverse osmosis water dispenser for the entire house, there are a few factors that you need to observe. Determine how much water is needed and consumed everyday. The average person uses about 50 to 75 gallons of water per day for drinking, cooking, toilet, washing, etc. Underdeveloped countries may require much less. Multiply the maximum amount by the number of individuals in the household.
Next, consider how much water storage is needed. The process takes time so reverse osmosis water dispensers usually produce water at a slower pace compared to consumption. The system however, continues to work even if there is little or no consumption. An auxiliary storage tank comes in useful to keep the water for future use. Ideally, choose tanks that can keep about one-half of the total daily consumption.
Also consider the daily reverse osmosis water production. Undersized systems running nonstop are at risk for premature wear while oversized units can hurt your budget. Size the reverse osmosis system properly in a way that it produces enough to supply your home's water requirements in at least an 8-hour period. This will help prevent damage and provide supply during high water demand periods.
Aside from the Dispenser
A reverse osmosis water dispenser will cleanse the water it takes in by as much as 90% to 95%. You might want to compliment or alternate it with other systems incorporating and storage components for added safety measure and extra source during cases of emergency. Experts recommended devices that feature a multimedia filter and activated granular carbon. Dangerous biological material, pathogens, chlorine and other chemicals will be removed as well as a number of healthy minerals.
Is Reverse Osmosis Really Right For You
Before seeking out a reverse osmosis unit, there is something that you should know about. Reverse osmosis removes mineral content. While there is no way to stop this, there are other water purification system on the market that you can review. Fortunately, you can find ones that provide clean water, and also retain minerals that can be beneficial for your health as well.
