Water Treatment Plants Ensuring Purity, Taste, and Compliance
July 23, 2025
In the competitive beverage industry, water quality is everything. Whether it’s packaged mineral water or flavored cold drinks, the base ingredient-water-must meet stringent standards of purity, taste, and safety. Water treatment plants designed for mineral water bottling units and soft drink manufacturing facilities are engineered to deliver precisely this. This article explores the end-to-end water treatment process, essential equipment, and regulatory considerations for beverage-grade water production.
Why is water treatment essential for mineral water and soft drink industries?
Raw water from borewells, rivers, or municipal supply often contains impurities such as:
- Physical contaminants (sand, silt, turbidity)
- Chemical compounds (chlorine, fluoride, nitrates)
- Biological hazards (bacteria, viruses)
Treating water ensures:
- Consistency in taste and quality
- Compliance with FSSAI, BIS, and WHO standards
- Product shelf stability and safety
What are the key stages in a water treatment plant for beverage production?
The typical process includes:
- Raw water storage and feed pump
- Pre-filtration (sand filter, activated carbon filter)
- Water softening or iron removal (if needed)
- Reverse Osmosis (RO) for dissolved salts
- UV sterilization and ozonation for microbial control
- Mineral dosing for bottled mineral water
- Polishing filter and storage tank
Each stage plays a specific role in purifying and conditioning water for end use.
How does the water treatment process differ between mineral water and soft drink production?
- Mineral water plants require re-mineralization (adding essential minerals like calcium, magnesium) post-RO.
- Cold/soft drink plants emphasize exact pH, conductivity, and carbonation readiness.
Thus, soft drink production may also include dechlorination and CO₂ compatibility testing.
Which equipment is commonly used in beverage-grade water treatment plants?
Key machinery includes:
- Multi-grade Sand Filter (MGF) for turbidity
- Activated Carbon Filter (ACF) for color, odor, and chlorine
- Micron Cartridge Filters (5–1 micron) for fine filtration
- Reverse Osmosis System
- UV Disinfection System
- Ozonator for final sanitization
- SS Storage Tanks with Float Valves
All piping and contact parts are preferably made from SS 304/316 to prevent contamination.
What are the water quality standards for mineral water in India?
As per IS:14543 for packaged drinking water and IS:13428 for natural mineral water:
- TDS: < 500 mg/L (Packaged)
- pH: 6.5–8.5
- No E. coli, Salmonella, or coliforms
- Heavy metals and pesticide levels below permissible limits
RO+UV+Ozonation systems help companies meet these parameters consistently.
How does reverse osmosis help in beverage water treatment?
RO membranes remove:
- Dissolved salts
- Heavy metals (arsenic, lead, etc.)
- Microorganisms and viruses
RO ensures consistent TDS and taste profile-a critical factor for cold drinks that undergo flavor mixing and carbonation.
What is the role of UV and ozonation in disinfection?
- UV Disinfection: Instant microbial inactivation using ultraviolet rays (254 nm)
- Ozonation: Oxidizes bacteria, viruses, and organic compounds
These are final-barrier treatments ensuring zero microbial load in the bottled product.
How do mineral water plants maintain taste while ensuring safety?
After RO strips water of all minerals, controlled re-mineralization restores palatability and nutritional value. This involves dosing:
- Calcium carbonate
- Magnesium sulfate
- Potassium salts
Advanced plants use online dosing pumps with digital flow controls for precision.

- Complete documentation (IQ/OQ/PQ, SOPs)
- After-sales support, AMC options
- Regulatory support for FSSAI, BIS, ISO 22000 approvals
Choosing a trusted partner ensures smoother operations, lower downtime, and easier expansion.
What is the ideal production capacity to start with for a small-scale mineral water plant?
A portable unit with 2,000–5,000 bottles per hour is ideal for small startups. Scale up based on market demand and distribution reach.
What are the common bottling types available (PET, glass, cans)?
PET is most popular due to being lightweight and recyclable. Glass is premium but more costly. Cans are less common in India but used for carbonated drinks abroad.
How much land is required for a mineral water or soft drink plant?
A compact plant can operate in 1,000–2,000 square feet. For larger, high-volume operations, 10,000+ sq ft is needed, including storage, utilities, and office space.
