CSIR develops two water purification technologies
CSIR has developed two water purification technologies. The Central Salt and Marine Chemicals Research Institute (CSMCRI), Bhavnagar and the National Chemical Laboratory, Pune have developed Ultrapore Filtration modules, using poly-sulfone/polyether solfone as well as poly acrylonitrile membrane. In addition, another CSIR lab, the Central Glass and Ceramic Research Institute, Kolkata, has developed a ceramic micropore filter water purification system.
The ultra filtration membrane has small sized pores that can exclude micro-organisms. The typical water flux depending on the water quality, is about 15 to 20 litres per hour for a domestic module and 45 to 60 litres per hour for community module. The UF assemblies have been made employing hand and foot pump, cycle pump and compact electrical pumps.
The micro filtration system is useful for the removal of arsenic and iron impurities from water. 40 such units have been supplied to NGOs for trials and evaluation of performance. Besides this, a 30,000 litre per day capacity plants have been set up at Allahabad to provide safe drinking water to pilgrims of Kumbh Mela, and at Radhanpur, to provide drinking water to earth-quake victims.
Also, ceramic micropore filtration units have been set up at Barasat in West Bengal where arsenic problem is acute. The technologies have been transferred to industry for commercialisation, says the CSIR.
