Reverse osmosis water filter systems are an important part of the solution to the growing world water crisis. They are the most effective technology for filtering out pollutants from water, but they are also more complex than other filtration systems. To help you understand the difference between reverse osmosis and other filtration systems, here is a brief overview of a reverse osmosis system.
Reverse Osmosis Systems:
Reverse osmosis (RO) is a water purification technology that uses a semi-permeable membrane to remove ions, molecules, and larger particles from drinking water.
Reverse osmosis systems are often used in areas where other kinds of water treatment methods are not available or are not cost-effective.
The process involves applying pressure to water, forcing it through the membrane, and removing the target substances. The result is water that meets or exceeds the standards for drinking water set by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO).
A reverse osmosis (RO) system has five basic components: membranes, pump, pre-filter, pressure vessel, valves, and controls. The most important component is the membrane element which removes contaminants from water under pressure as it passes through pores in the membrane.
The application of this process removes many types of dissolved salts, minerals, metals, chemicals, and other contaminants from water. It does not remove microbes (typically bacteria), viruses, or particulate matter.
Reverse Osmosis (RO) is commonly used for drinking water treatment and desalination of seawater and brackish groundwater. It involves putting water under pressure, forcing it through a semi-permeable membrane, and removing the unwanted elements, leaving clean drinking water behind.
