What is Reverse Osmosis (RO)?

In simple terms, RO is a separation process that uses pressure to force raw water through a membrane. This membrane will retain the contaminants on one side and allow pure water to pass through to the other side. Because contaminants in water are finer and more minute, carbon filters are also used in water filtration systems to complement the RO filters.

What are the benefits of installing or purchasing an RO water system?


  • The RO process can treat a variety of contaminants including:
    Aluminum, Arsenic, Asbestos, Atrazine, Benzene, Chlorides, Chlorine, Copper,
    Cryptosporidium, Cyanide, Fluoride, Giardia, Lead, Mercury, Nitrates, Radium,
    Radon, Silver, Sodium, Sulfide, Trichloroethylene, and Total Trihalomethanes
  • Cleaner, healthier drinking water
  • No chlorine smell or taste – keeps your food and drinks free from the chemicals present in untreated water
  • It is believed that using RO-purified water in household appliances such as steam irons can keep them working longer and more efficiently

Who should consider purchasing a reverse osmosis system?

Anyone concerned about the quality of the water they are consuming. Be it at home, the office or your business premises.

How do I select the right water treatment system for my needs?

First of all, determine if the system is going to be for home, the office or your business premises. Offices and business premises will most likely require a higher capacity water system.

Second, what are your preferences? Are you looking for a water system that just dispenses drinking water? Or a water system to purify your entire water works? If you have decided on the former, do you want a hot and cold dispenser? Or a unit that dispenses water at room temperature? All these questions will lead you to the right water system and model.
