    Physicochemical Parameters
    TDS 2000

    Total dissolved solids (TDS) refer to the combined content of all inorganic and organic substance contained in a liquid; these are present in a molecular, iodised, or micro-granular suspended form. RO systems are specifically designed to effectively remove TDS to a great extent. Where the TDS level of supply/ground water is high, from 1,000 up to 2,500–3,000, it is recommended that RO systems be installed for drinking-water purpose. A special cellulose membrane cartridge plays a key role in removing TDS from the input water.

    As per Indian Standard, an RO system shall reduce TDS level of feed water to less than or equal to 500 mg/l.

    • Al brands reduced the TDS to below the limit specified (500 mg/l) when the input level was maintained at a fixed level.
    • Tata Swach scored highest on this parameter, followed by Aquaguard.
    • Some brands reduced the TDS level to below 100, which is also not desirable due to their reducing the intake level of essential minerals.

    General Qualities
    Storage Capacity 4.2

    Water-storage capacity should be as declared by the manufacturer.

    • In five brands – Tata Swach, Electrolux, Usha, Aquaguard and Pureit – the water-storage capacity was found to be less than the declared.
