CSIR-CMERI for the very first time has come up with a dual solution of excess F– (fluoride) and Fe3+ (iron) mitigation from ground water.
The present invention reveals about proper design and subsequent development of an integrated, low-cost, commonly available multi-adsorbent based community level (high flow rate) water purification system for effective and simultaneous removal of fluoride and iron (below WHO permissible limit) in an efficient manner from contaminated water.
The contamination of fluoride and iron in drinking water is increasing day by day.
Iron in the Body
- Iron is the most abundant trace element in human body, responsible for accomplishment of vital biological functions such as gastrointestinal processes and the regulation of body temperature.
- But when iron level in water is beyond 0.3 ppm (as per WHO guideline), it shows several adverse effects including liver disease, irregular heart rhythm and neuronal disorder etc.
Restricted dose of fluoride
- Restricted dose of fluoride ( less than 1.5 ppm, as per WHO guideline) in drinking water is required for proper strengthening of teeth and bones in human body.
- But intake of excess fluoride can affect human health profusely by causing dental and skeletal fluorosis initially, which leads to a crippling malady in the long run.
- About 60-70 million people of India have been indicated to be at excess (fluoride) F– threat.
