Answer: After you install a new filter (this is the case with all brands of filter cartridges) you should run it for a few minutes. Generally cloudy or white water indicates air in the line and this is natural and normal with the replacement of a filter cartridge. Air will enter in the housing, lines […]
Answer: Most brands of RO system will reduce 90% plus of salts in water, so you can assume the water salts concentration would be about 1/9th of the content in the feed water. The aggressiveness of this purified water towards the materials into which it comes in contact is a function of its purity. The […]
Answer: Our high quality Reverse Osmosis systems use a process known as crossflow to allow the membrane to continually clean itself. As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected contaminants away from the membrane and down the drain. This prevents contaminants from backing up against the membrane […]
1. When the UV unit is installed in a horizontal position, the direction for the water flow can be either to the left or to the right ~ no preference. 2. When the UV is installed in a vertical position, the water flow Must be up; ie the water must enter the lower fitting and […]
Answer: The filters of your RO system should be changed periodically. In general, both the pre- and post-filters should be replaced about every six months, or at least annually; however, the maintenance schedules may vary due to local water conditions, the quality of water being filtered and if you have other water pre-treatment such as […]
Answer: RO systems are capable of removing certain biological contaminants such as Cryptosporidium and Giardia. The pore size of the RO membrane along with the amount of pressure applied to the water will generally determine the rate of reduction of such contaminants. The Water Quality Association (WQA) states, that while RO membranes are reliable for […]
Answer: No, they run on water pressure. You need electricity only if you add an electric pressure-boost pump to increase the system’s performance or an ultraviolet light to be certain that your water does not have any bacteria. Both of these items are options on most RO units and the decision to select options will […]
Answer: With the exception of a few proprietary RO system manufacturers, all residential membranes are the same size and all fit in the same membrane housing. When the residential RO market first started to come alive, nearly all of the membranes where 8 to 10 gallons per day systems. Many of the proprietary membranes are […]
Background Some folks would have you believe that Reverse Osmosis (RO) water is some high-tech, super, genetically altered water that could one day destroy the world. Nothing is farther from the truth. Reverse Osmosis is just a filter with much smaller holes than other filters. Reverse Osmosis is just a normal film based filter that […]
The statement that Reverse Osmosis (RO) is expensive may be true or false depending on a variety of factors. But generally speaking, reverse osmosis systems do have a greater start-up cost than faucet and counter-top filters. Quality RO systems will last up to 10-15 years and should be looked at as a long term investment. […]
