Reverse Osmosis (RO) is recognized by experts as the best technology available to remove the widest spectrum of contaminants found in drinking water (e.g. bacteria, virus, flouride, arsenic, dissolved heavy metals, nitrate, microbial contaminants, salts).

What Is Reverse Osmosis?

Reverse Osmosis (RO) is a process by which water molecules are forced through a 0.0001 micron semi-permeable membrane by water pressure. Long sheets of membrane are sandwiched together and rolled up around a hollow central tube in spiral fashion, commonly referred to as spiral wound membrane. RO membranes are available in different sizes for processing different quantities of water.

The RO membrane is housed in a housing so that pressure can be maintained on its surface. This pressure forces the water through the membrane, separating it from the unwanted substances like dissolved chemicals, heavy metals, suspended solids, arsenic, salts and other impurities. These unwanted substances are diverted to a waste drain so that they do not build up in the system, thus keeping the RO membrane clean.
