High Flow Rate Water Purification Technology for Fluoride and Iron Removal
- The contamination of fluoride and iron in drinking water is increasing day by day.
- 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.
- Similarly, 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.
- According to the report by Ministry of Drinking Water and Sanitation, the groundwater in more than ten thousand five hundred rural habitations distributed in various states of India are found to be contaminated with elevated fluoride concentration.
- Therefore, there is a need of affordable water purification technology for fluoride and iron removal.
- CSIR-CMERI for the very first time has come up with a dual solution (excess F– and Fe3+ 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 CSIR-CMERI developed Fluoride and Iron removal system is comprised of three staged purification system.
- The first FRP make vessel (Chamber-I) is for rapid removal of precipitated iron.
- The next one(Chamber-II) is one of the most crucial chambers for removal of the left over iron from the contaminated water.
- In final stage fluoride will be removed from contaminated ground water by ‘fluoride removal unit’ (Chamber-III), where the adsorbents will fulfil the purpose of fluoride mitigation.
UNIQUENESS OF THE PRESENT PLANT:
- An initiative towards solving dual contaminants problem in ground water (F– as well as Fe3+)
- An integrated adsorbent based water purification system for effective removal of fluoride as well as iron in an efficient manner from contaminated water bodies.
- High flow rate (10,000 litres/h) integrated purification system.
- Sustainability towards healthy livelihood generation.
- Selective backwash without dismantling any part of the plant.
Goa becomes first 'Har Ghar Jal' State across the nation by providing tap water connection to every rural household
- Goa has earned itself the unique distinction of becoming first ‘Har Ghar Jal’ State in the country as it successfully provides 100% Functional Household Tap Connections (FHTCs) in the rural areas covering 2.30 lakh rural households.
- Harnessing the immense benefits of efficiently utilising the Jal Jeevan Mission (JJM) which aims to improve the quality of life and bring ‘ease-of-living’ to rural communities that all rural homes in the State now have a tap water supply.
- State’s commitment and brisk efforts have ensured advancement and achievement of targets well before time.
- In June, 2020, the Union Minister of Jal Shakti, Shri Gajendra Singh Shekhawat wrote to the Chief Minister of Goa expressing his happiness on the State’s Annual Action Plan (AAP) to provide 100% Functional Household Tap Connections (FHTCs) in rural areas by 2021 and extended full support for the implementation of Mission reiterating that providing potable water is a national priority for the Union Government.
- Accordingly, fund allocation to Goa in 2020-21 has been increased to Rs. 12.40 Crore.
- Besides, the State could also explore through convergence of various programmes like MGNREGS, SBM (G), 15th FC Grants to PRIs, District Mineral Development Fund, CAMPA, CSR Fund, Local Area Development Fund, etc. for strengthening of drinking water sources, water supply, grey water treatment & re-use and operation & maintenance.
- The two districts of Goa i.e. North Goa with 1.65 lakh rural households and South Goa with 98,000 rural house holds in 191 Gram Panchayats are fully saturated with assured piped water supply through tap connections.
- To strengthen the water testing facilities, the State is in process of getting 14 water quality testing laboratories NABL accredited. Jal Jeevan Mission mandates training 5 persons in very village especially women to be trained in using Field Test Kits, so that water can be tested in the villages.
- Goa’s achievement is an example for other States to emulate and ensure every rural home gets tap connection and especially in these times of CoVid-19 pandemic, it is all the more imperative to have assured safe water supply within households.
- This silent revolution happening in rural India in terms of household tap water connections is a work in progress for a ‘New India’.
- Having achieved the universal access, the State now plans for sensor-based service delivery monitoring system so as to monitor the functionality of water supply i.e. potable water in adequate quantity and of prescribed quality being provided to every rural household on regular and long-term basis.
Indigenously Developed Anti Radiation Missile (RUDRAM) has been successfully tested
- New generation Anti Radiation Missile (RUDRAM) was successfully Flight tested onto a radiation target located on Wheeler Island off the coast of Odisha.
- The missile was launched from SU-30 MKI fighter aircraft.
- The RUDRAM is first indigenous anti-radiation missile of the country for Indian Air Force (IAF), being developed by Defence Research and Development Organisation (DRDO).
- The missile is integrated on SU-30 MKI fighter aircraft as the launch platform, having capability of varying ranges based on launch conditions.
- It has INS-GPS navigation with Passive Homing Head for the final attack.
- The RUDRAM hit the radiation target with pin-point accuracy.
- The Passive Homing Head can detect, classify and engage targets over a wide band of frequencies as programmed.
- The missile is a potent weapon for IAF for Suppression of Enemy Air Defence effectively from large stand-off ranges.
- With this, the country has established indigenous capability to develop long range air launched anti-radiation missiles for neutralising enemy Radars, communication sites and other RF emitting targets.
