Reverse Osmosis Big Flow Commercial RO Membrane 300GPD household Membrane Fitler
Reverse Osmosis (RO) water filtration is a cost effective and safe way to improve the quality of drinking water. Ranging in size from a small RO water filtration systems at a kitchen sink to a large commercial system in a manufacturing plant, reverse osmosis technology is used throughout the world to effectively remove impurities found in water.
Reverse osmosis elements are commonly classified by the type of membrane used in the element, the diameter of the element, the length of the element and the type of outer wrap of the element.
The selection of membrane varies accordingly with the application and feed water source. There are different types of membranes used to treat tap water, brackish water, seawater and wastewater. Regardless of the specific type of membrane, the performance of a membrane is specified and compared based on its rate of water production and the percent of total salts it retains. In theory, the ideal membrane performance is the highest water production rate with the highest salt rejection at the lowest feed pump pressure. However, in practice, to achieve the highest water production rate comes at the expense of achieving the highest salt rejection or vice versa. Over the years through continued innovation in membrane technology, this compromise or balance has gotten closer to the ideal and yielded a wider selection of membrane performance characteristics along the way.

Q: What is a residential RO Water Filter?
It is a system that uses the principle of reverse osmosis to remove 95-99% of all the mineral and chemical contaminants from raw tap water. It gives you the quality of bottled water with the convenience of a faucet mounted on your kitchen sink.
Q: How does RO Water Filter different from a water filter?
Ordinary water filters use a screen to separate only particles of dirt sediment from water. RO water filter employs a semi-permeable membrane that removes not only particles but also an extremely high percentage of dissolved contaminants, molecule by molecule, from raw tap water.
Q: Will RO Water Filter remove sodium from the water?
Yes! Reverse osmosis was originally designed to make seawater drinkable for the Navy. It is ideal for anyone on a low sodium diet.
Q: Does RO Water Filter remove bacteria? Cryptosporidium?
YES! A reverse osmosis membrane has a pore size much smaller than bacteria, virus pyrogen, or the Cryptosporidium parasite. When functioning properly, it will remove all microorganisms from tap water and produce sterile water.
Q: Don't we need the minerals that are removed from the water?
Most of the minerals that we receive are from the foods we eat. Only a very small percentage comes from the water we drink.
