OXYTEJ Water Purification Process
1. Raw Water Collection
Every journey begins with carefully sourced raw water from approved underground water sources. The water is collected in a dedicated raw water storage tank where its quality is monitored before entering the purification system.
Purpose:
- Collect water from a reliable source
- Maintain consistent supply
- Initial quality inspection
2. Aeration (If Required)
If the source water contains dissolved gases such as hydrogen sulphide or excess iron, it is aerated. During this stage, water is exposed to air to improve its quality and remove undesirable gases and odours.
Removes
- Hydrogen Sulphide
- Carbon Dioxide
- Iron Oxidation
- Unpleasant Odours
3. Multi-Grade Sand Filtration
Water passes through layers of specially graded quartz silica sand that trap suspended particles, dirt, clay, silt, rust and other visible impurities.
Removes
- Dust
- Mud
- Sand
- Suspended Solids
- Sediments
Benefits
- Improves clarity
- Protects downstream filters
4. Activated Carbon Filtration
The water then flows through premium activated carbon media that adsorbs chlorine, pesticides, organic compounds, colour and unpleasant taste or odour.
Removes
- Chlorine
- Organic Chemicals
- Colour
- Bad Taste
- Bad Odour
Benefits
- Crystal-clear taste
- Protects RO membrane
5. Water Softening
If hardness is present, the water passes through a softener where calcium and magnesium ions are exchanged with sodium ions.
Removes
- Calcium
- Magnesium
Benefits
- Prevents scaling
- Improves RO efficiency
6. Anti-Scalant Dosing
A food-grade anti-scalant chemical is carefully dosed before Reverse Osmosis to prevent mineral deposits on the membrane surface.
Benefits
- Longer membrane life
- Better purification efficiency
7. Micron Cartridge Filtration (10 Micron)
Water passes through a 10-micron cartridge filter.
Removes
- Fine Dust
- Small Suspended Particles
8. Micron Cartridge Filtration (5 Micron)
A second cartridge filter removes even finer particles before the RO membranes.
Removes
- Microscopic Sediments
- Remaining Suspended Matter
9. High Pressure Pump
A stainless-steel high-pressure pump forces water through Reverse Osmosis membranes at controlled pressure.
Purpose
- Maintain required RO pressure
- Ensure efficient purification
10. Reverse Osmosis (RO)
This is the heart of the purification system.
Water passes through semi-permeable RO membranes where dissolved impurities are separated from pure water.
Removes
- Total Dissolved Solids (TDS)
- Heavy Metals
- Lead
- Arsenic
- Mercury
- Cadmium
- Fluoride
- Nitrates
- Sulphates
- Pesticides
- Harmful Chemicals
- Viruses
- Bacteria
- Protozoa
Result
Ultra-pure drinking water.
11. UV Sterilization
Purified water passes through high-intensity ultraviolet light.
UV damages the DNA of microorganisms, preventing them from multiplying.
Eliminates
- Bacteria
- Viruses
- Fungi
- Microorganisms
No chemicals are added during this process.
12. Ozonation
Food-grade ozone gas is infused into purified water.
Ozone is one of the most powerful disinfectants used in bottled water manufacturing.
Benefits
- Final disinfection
- Maintains freshness
- Prevents microbial growth
- Extends shelf life naturally
13. Mineral Balancing
Since RO removes almost all dissolved minerals, essential minerals are carefully balanced (if applicable) to achieve a pleasant taste while meeting applicable packaged drinking water standards.
Balanced Minerals
- Calcium
- Magnesium
- Potassium (if used)
Benefits
- Refreshing taste
- Balanced mineral composition
14. Storage in Sanitized Stainless Steel Tank
The purified water is stored inside food-grade SS-304/SS-316 stainless steel tanks.
These tanks are regularly sanitized to maintain hygienic conditions before bottling.
15. Bottle Washing & Sanitization
Empty bottles are automatically washed using purified water and sanitized before filling.
Cleaning Stages
- Inverted Bottle Cleaning
- High Pressure Rinsing
- Sanitization
- Final Purified Water Rinse
16. Automatic Filling
The purified water is transferred into bottles using fully automatic filling machines operating inside a hygienic environment.
Advantages
- No human contact
- High accuracy
- Hygienic filling
17. Automatic Capping
Each bottle is immediately sealed using tamper-proof caps.
This protects the water from contamination during storage and transportation.
18. Batch Coding & Labeling
Every bottle receives
- Manufacturing Date
- Batch Number
- Expiry Date
- MRP
- Product Information
Premium labels are then applied automatically.
19. Quality Control Laboratory Testing
Every production batch undergoes rigorous testing.
Physical Tests
- Colour
- Taste
- Odour
- Turbidity
- TDS
- pH
Chemical Tests
- Hardness
- Chlorides
- Sulphates
- Fluoride
- Iron
- Nitrates
Microbiological Tests
- Total Plate Count
- Coliform
- E. coli
- Yeast
- Mould
Only batches meeting quality standards proceed to packaging.
