Permissible Range Of Total Dissolve Solid (TDS) In Drinking Water

- Aug 04, 2018 -

Total dissolved solids (TDS)

comprise inorganic salts and small amounts of organic matter that are dissolved in water. The principal constituents are usually the calcium, magnesium, sodium and potassium and the anions carbonate, bicarbonate, chloride, sulphate and, particularly in groundwater, nitrate .TDS is expressed in units of mg per unit volume of water (mg/L) or also referred to as parts per million (ppm).

Permissible range of TDS in drinking water

Different government has different regulations for the TDS level. Jordan sets the maximum contaminant level for TDS 500 ppm whereas WHO has different prescribe limits.

Best TDS Level Suggested

In entire world water Filters / Purifiers TDS level cannot be regulated except in the new innovation of KENT's Mineral RO™ Technology.

Where the TDS level should be between (50 - 150) ppm for normal working people.

It is considered that people who have kidney problem, might have water level below 100ppm which might help in their health situation.

The Great Innovation

Keeping in mind the disadvantages of RO technology, KENT has invented a new technology called the KENT's Mineral RO™ Technology. This patented technology has all the benefits of the RO technology, while eliminating its limitations.

KENT’s patented KENT's Mineral RO™ Technology uses an innovative TDS (total dissolved solids) control valve which allows the user to control the amount of essential natural minerals present in drinking water.

It ensures that the RO purified water does not have a bitter taste and the pH is maintained around 7.

It also enables the user to adjust the amount of TDS in purified water according to one’s taste.

This technology is based on double purification wherein water after passing through RO, is also passed through Ultra Violet (UV) radiation and Ultra Filtration (UF).

Secondary purification by UV/UF ensures that when the pores of RO membrane open up and allow harmful micro-organisms to pass through, they get deactivated/filtered out by UV/UF.Health Organization, a panel of tasters & health came to the following conclusions about the preferable level of TDS in water
