- Case Study: Cities such as Chennai and Delhi have implemented RO facilities for extensive water purification to tackle groundwater pollution.
- Limitations: Demands energy and regular upkeep, raising financial concerns for economically disadvantaged groups.
2. UV Filtration
- Mechanism: Utilizes ultraviolet light to eliminate or deactivate microorganisms found in water.
- Effectiveness: Efficient against viruses, bacteria, and protozoa without adding harmful substances.
- Health Benefits: Lowers the occurrence of waterborne ailments such as cholera and dysentery.
- Examples: Various NGOs are implementing portable UV filtration units in rural locales, enhancing access to clean drinking water.
- Limitations: Dependent on electricity and may not address chemical contaminants.
3. Bio-Sand Filters
- Mechanism: Combines sand and gravel with a biological layer for natural water treatment.
- Effectiveness: Ideal for home use and reduces turbidity, pathogens, and suspended solids.
- Health Benefits: Lowers the chances of infections by providing families with clean, safe water.
- Case Study: Initiatives in states like Kerala have promoted bio-sand filtering, empowering communities to purify their own water supply.
- Limitations: Necessitates regular maintenance and may struggle in severely polluted water sources.
4. Activated Carbon Filtration
- Mechanism: Passes water through activated carbon, which absorbs organic pollutants and odors.
- Effectiveness: Particularly efficient in removing chlorine, volatile organic compounds (VOCs), and additional chemicals.
- Health Benefits: Enhances taste and smell, thereby encouraging increased water consumption, which benefits overall wellness.
- Example: In urban settings, activated carbon filters are gaining traction as household solutions.
- Limitations: Requires frequent replacement of the carbon media, potentially incurring ongoing expenses.
5. Solar Water Disinfection (SODIS)
- Mechanism: Leverages solar power to cleanse water contained in clear bottles, utilizing UV light and heat.
- Effectiveness: A straightforward and cost-effective approach, especially in rural regions with limited infrastructure.
- Health Benefits: Diminishes waterborne diseases in low-income households by providing a sustainable purification approach.
- Case Study: NGOs in Rajasthan utilize SODIS as an educational resource, demonstrating its effectiveness in community workshops.
- Limitations: Dependent on weather conditions and requires transparent bottles, hindering effectiveness during cloudy days.
Effectiveness of Water Purification Techniques
1. Health Impact
- Reduction in Diseases: Adoption of purification techniques has resulted in a noticeable decline in the incidence of waterborne illnesses.
- Access to Clean Water: Improved availability of treated water significantly enhances public health indicators.
