Bisleri's Purification Process: A Detailed Look
Bisleri is a well-known brand, and its reputation is largely due to its multi-stage purification process designed to ensure safety and purity. The company promotes a 10-step process that removes impurities and adds minerals.
The 10-Step Purification Journey
The process consists of the following steps:
- Water Collection: The water is sourced and undergoes initial testing.
- Ozonisation: Ozone kills micro-bacteria and pathogens.
- Sand Filtration: This removes particles like sand and dust.
- Carbon Filtration: Activated carbon removes odor, color, and organic contaminants.
- Reverse Osmosis: This step removes salts, solids, and other impurities, further purifying the water.
- Mineralisation: Minerals such as magnesium sulphate and potassium bicarbonate are added to enhance taste and replenish electrolytes.
- Micron-filtration: This process removes the smallest remaining particles.
- Re-ozonisation: A second dose of ozone ensures purity and extends shelf life.
- Careful Bottling: Bottles are made on-site to minimize contamination, and filling happens under sterile conditions.
- Quality Control: Each sealed bottle undergoes final checks before distribution.
Quality Control: Ensuring Purity
To ensure the final product is safe, Bisleri claims to perform over 100 quality tests throughout the process. This helps maintain the brand’s promise of pure water. Manufacturing bottles in-house and performing regular checks helps prevent contamination.
Mineral Content and Health Implications
Bisleri re-mineralizes its product, unlike purified water that lacks minerals. Adding minerals like magnesium sulphate and potassium bicarbonate can offer minor health benefits, contributing to daily mineral intake and maintaining a balanced pH in the body. However, the mineral content is not a replacement for a balanced diet.
Potential Risks of Daily Consumption
Though the purification process is thorough, there are concerns about bottled water consumption, especially with daily intake.
Microplastics and Chemical Leaching
Most bottled water uses PET (polyethylene terephthalate) plastic bottles. Research shows microplastics can leach from these bottles into the water over time, especially when exposed to heat,. Early studies suggest potential risks from microplastic consumption. BPA, another chemical used in some plastics, has also raised concerns about hormone disruption. Some recommend glass containers to reduce these risks.
Mineral Overload and Health Conditions
Some mineral waters, including certain Bisleri varieties, contain sodium. Those on a low-sodium diet should be cautious. In rare cases, for individuals with pre-existing kidney issues, high mineral content could strain their kidneys. Consulting a doctor is important for any health concerns.
Batch Consistency and Bottle Tampering
Though Bisleri's process is robust, the brand has faced issues, particularly with unauthorized manufacturers. For example, in 2019, an advisory was issued in Meghalaya to avoid Bisleri from a specific manufacturer due to high fluoride levels. Fake or refilled Bisleri bottles also pose a contamination risk, which compromises the brand’s quality. Buying from reputable vendors and checking the seal is vital.
Bisleri vs. Tap Water: A Comparison
Choosing between Bisleri and tap water depends on local tap water quality. The following table provides a comparison:
| Feature | Bisleri Packaged Water | Good Quality Tap Water | Unfiltered Tap Water |
|---|---|---|---|
| Purity | Rigorously purified and tested; high safety standards. | Generally safe and constantly monitored by public utilities. | May contain bacteria, chemicals, or heavy metals depending on the source. |
| Mineral Content | Minerals added back for taste and benefits. | Contains naturally dissolved minerals, which can be beneficial. | Variable; may or may not contain beneficial minerals. Can contain harmful substances. |
| Cost | Significantly more expensive than tap water. | Very low cost, especially compared to bottled water. | Low cost. |
| Environmental Impact | High plastic waste from PET bottles, though Bisleri promotes recycling. | Low environmental impact; delivered via public infrastructure. | Can be a low impact option if safe and not requiring filtration. |
| Convenience | Highly convenient for on-the-go hydration. | Always available from the tap at home. | Requires filtration or boiling to be safe for daily consumption in many places. |
Conclusion: Making the Best Choice
So, is it safe to drink Bisleri water daily? It is generally safe for most healthy individuals if the bottles are genuine and from a trusted source. Bisleri's purification and mineral enrichment make it a safe option for daily hydration. However, long-term daily consumption of bottled water raises concerns about microplastics, chemical leaching, and plastic waste,,. For those seeking an alternative, properly filtered tap water can be more sustainable and cost-effective, offering similar safety and purity. The final choice depends on tap water quality, personal health, budget, and environmental values.
