ITI transferes technology on water filter


Memorandum of understanding (MoU) was signed between ITI and Sri Lanka Red Cross Society for transferring the technology on manufacturing clay water filter which can remove fluoride, arsenic and cadmium. The water filter has been developed by the Materials technology Section of ITI after six years of continuous R&D work. The MoU was signed in 2016 at ITI between the Sri Lanka Red Cross Society and ITI and the technology was transferred in 2017.

There are many unique features in the ITI developed clay water filter when compared with the other water filters in the market:

  •              Low initial investment and maintenance cost
  •  Two years of filter life-time for removal of arsenic and cadmium and requires

          regeneration of filter using a simple method for   fluoride in every 3 months

  • It is also observed the filter has the ability to reduce water hardness resulting fresh taste

          of filtered water

  • The filter exhibits antibacterial properties to a certain level which is due to an inherited

          characteristic of the clay.

  •  Further studies on elimination of water hardness and development are in progress.

The North Western Provincial Council distributed the ITI filter freely among 1000 families in northwestern province in 2015. 

More than 5000 ITI filters have been distributed among families in North Western and North Central Provinces who is affected by CKDu during 2017-2018 by the Presidential Task Force - CKDu Unit.
