Reverse Osmosis

Reverse Osmosis is the process in which pure water is produced by forcing water through a semipermeable membrane across which impurities cannot pass, separating pure water from most of the substances dissolved within it.

Reverse osmosis uses an applied pressure gradient across a semipermeable membrane to overcome osmotic pressure and remove water molecules from the solution with hardness ions. The membrane has pores large enough to admit water molecules for passage but not hardness ions such as calcium and magnesium. The resulting soft water supply is free of hardness ions, and the vast majority of other contaminants, without any other ions being added. Membranes are a type of water filter requiring regular cleaning or replacement maintenance.

Reverse Osmosis can help with the removal of hard water ions, particulates, chlorine, TDS (total dissolved solids), alkalinity and pH.


Reverse Osmosis System Components

  • Intake Valve – connects the main water supply to the RO system.
  • Pre-Filter – removes large particles and sediment.
  • Pressure Vessels – hollow tubes containing the membrane.
  • RO Membrane – one or several membranes trap most contaminants.
  • Pressure System – water or electrical pumps that make the system work.
  • Valves – control the system flow to prevent back-flow and blockage.
  • Storage Tank – holds the purified water (permeate).
  • Drain Line – carries the dirty water away.
  • Post-Filter – usually activated carbon to remove micro-pollutants.
