What Is Reverse Osmosis, And How Does It Work?

Reverse osmosis water purification uses an ultra-fine membrane with small holes to separate the contaminants from the water. It is equipped with granular carbon and sediment filters that are used as both pre and post-filters. The process involves:

  • Using a pre-filter to remove chlorine and sediment before passing through the membrane
  • The RO membrane removes any leftover or dissolved contaminants or solids
  • It passes through post filters to improve water quality before entering the faucet

Reverse Osmosis systems require high pressure for the system to operate efficiently. The water filtration through the permeable membrane is a slow process that works best with a pressurised water pump or storage tank.

In tankless RO systems, the pump provides adequate pressure to send the water to be filtered and accessed through the tap. Whereas in systems with a storage tank, the filtered water is stored in the tank, with the system shutting off when the tank is full.

The water in reverse osmosis water filter systems is directed in two flows; where the clean water goes towards the faucets and the wastewater flows towards the drain. The system must be cross-connected to the water and drain line to prevent the clean and dirty water from mixing.

Reverse osmosis water filtration systems are the most effective form of removing organic compounds, dissolved solids, metals, chemicals, viruses and pollutants. They provide extensive filtration in multiple steps to give you high quality, clean and fresh-tasting water.
