Understanding Reverse Osmosis Systems
What is Reverse Osmosis?
Reverse osmosis is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules, and larger particles from drinking water. The process involves applying pressure to the water, forcing it through the membrane while leaving the impurities behind. This results in clean, purified water that is ready for consumption or further treatment.
How Does Reverse Osmosis Work?
Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove ions, unwanted molecules, and larger particles from drinking water. Here’s a detailed look at how reverse osmosis works:
High-Pressure Pump: RO utilizes a high-pressure pump to increase the pressure on the salt side of the RO, typically around 200-400 psi for residential systems, and force the water across the semi-permeable RO membrane.
Semi-Permeable Membrane: The heart of the RO system is the semi-permeable membrane, which allows water molecules to pass through while trapping dissolved salts, minerals, and other impurities.
Salts Removal: As the water is forced across the membrane, around 95% to 99% of dissolved salts, heavy metals, and contaminants are left behind, accumulating on the reject stream side.
Pressure Requirement: The amount of pressure required depends on the salt concentration of the feed water. Higher salt concentration requires higher pressure for effective separation.
