The HDX RO-450 system is a four (4) state reverse osmosis system capable to produce up to 189 liters of clean drinking water per day (50 GPD).

This is a reliable system made by HYDROGUARD USA

Residential Applications
This Reverse Osmosis system is designed to produce the highest purified water for drinking, cooking, washing your fruits and vegetables.

Reverse Osmosis Method
In simple terms, reverse osmosis works as water is forced across a semi-permeable membrane, leaving contaminants behind that are flushed down the drain. The clean drinking water collects in a holding tank.

Reverse osmosis (RO) is a special type of filtration that uses a semi-permeable, thin membrane with pores small enough (0.0001 micron) to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria and viruses.

Reverse Osmosis is the best and most effective method to remove up to 99.8% of impurities, including bacteria and viruses. The combination of pre-filters together with the semi-permeable membrane provides excellent quality of clean & pure drinking water. In general, the reverse osmosis system removes solids, chemicals, heavy metals, pesticides, chlorine, arsenic, aluminum, boron, cryptosporidium, fluoride, potassium nitrates, volatile organic compounds VOCs, etc. that may exist in the water.

    • Material: Plastic parts with metal base
    • Dimensions: (H) 450 mm x (W) 360 mm x ( B ) 150 mm
    • Filtering Stages: 4
    • Metal PAE Storage Tank: 10.5 liters @ 40psi (Total Volume 17 liters), dimensions Φ 280 mm X H 420mm



    STAGE 1: Sediment Filter 5 micron: Removes suspended solids with a diameter greater than 5 micron i.e dirt, rust, sediments.

    STAGE 2: Carbon Block filter. Removes chemicals i.e chlorine, bad odors and taste.

    STAGE 3: 50 GPD semi-permeable membrane. Due to the special semi-permeable membrane, sufficient drinking water can be purified of all kinds of harmful impurities, including viruses and bacteria. RO membrane pores are 200 times smaller than viruses, and 4000 times smaller than bacteria.

    STAGE 4: Post Carbon "In-Line" filter that removes chlorine taste, odors and organic chemicals that contribute to bad taste.
