Reverse Osmosis
Reverse Osmosis reduces some contaminants through molecular filtration.

How Does Reverse Osmosis Work?

• Water is forced under pressure through a synthetic, semi-permeable membrane
• The membrane is designed to allow treated water to pass through its structure leaving behind most contaminants to be flushed away.

Advantages

• Effective removal of some inorganics, bacteria and viruses when membranes are new.
• Low energy to run.
• Ease of installation and maintenance.

Disadvantages

• Not effective on some microbiological contaminants.
• Effectiveness reduced over time requiring membrane replacement.
• Unable to remove small organic molecules.
• Wastes water.
• Membranes are sensitive to back pressure, temperature, pH, TDS, etc
• Can be fouled by iron, manganese and hardness minerals.
• Some membranes can be damaged by chlorine and other disinfectants.
• Membranes can form breeding grounds for bacteria.
• High replacement cost of membranes
• Must be constantly monitored
