Mineral Water Plant

A mineral water plant is a facility dedicated to the production and bottling of purified and often mineral-enriched drinking water. The process typically involves sourcing raw water, subjecting it to various purification steps, optionally adding minerals, and then bottling it for commercial distribution.

Types of Mineral Water Plant

Packaged Drinking Water: Water that has been purified through processes like reverse osmosis, filtration, and disinfection, and then bottled. Often refers to water that may not contain natural minerals, or has minerals added back.

Natural Mineral Water: Water sourced from a protected underground reservoir, naturally pure, and characterized by its constant composition of minerals and trace elements. It is minimally treated (e.g., filtration, ozone for disinfection) to preserve its original properties.

Sparkling Mineral Water: Natural mineral water or purified water infused with carbon dioxide to make it effervescent.

Flavored Water: Purified or mineral water with added natural or artificial flavors.

Applications in Various Industries

Food & Beverage Industry: The primary application, serving consumer demand for safe, convenient, and often premium drinking water.

Hospitality & Tourism: Providing bottled water in hotels, restaurants, and resorts.

Retail & Supermarkets: Dominant presence on shelves for consumer purchase.

Technology in a Mineral Water Plant:

Water Source & Pre-treatment: Borewells, municipal supply, or surface water. Pre-treatment includes sand filters, activated carbon filters, multi-media filters to remove suspended solids, chlorine, and organic matter.

Purification:

Reverse Osmosis (RO): A key technology to remove dissolved solids, salts, bacteria, and viruses.

Ultrafiltration (UF) / Nanofiltration (NF): Membrane filtration for removing smaller particles, colloids, and some dissolved solids.

UV Sterilization: Disinfection using ultraviolet light to kill microorganisms.

Ozonation: Disinfection and oxidation using ozone gas, which breaks down into oxygen, leaving no residual chemicals.

Mineral Dosing (Optional): Automated systems to add food-grade minerals like calcium, magnesium, and potassium to achieve desired taste and health benefits.

Bottling Line: Automatic bottle rinsing, filling (volumetric, gravimetric), capping, labeling, date coding, shrink wrapping, and palletizing.

Quality Control: Inline sensors, laboratory testing for microbial counts, pH, TDS (Total Dissolved Solids), and mineral content to ensure compliance with BIS (Bureau of Indian Standards) IS:14543 or international standards.

Material Selection Considerations

• Water Contact Parts: Food-grade stainless steel (SUS304, SUS316) is paramount for all pipes, tanks, pumps, and machinery parts that come into contact with the water, ensuring hygiene and preventing contamination/corrosion.
• Membranes: Polymeric materials (e.g., polyamide for RO, polysulfone for UF) specifically designed for water filtration, chosen based on pore size and chemical resistance.
• Filter Media: Sand, gravel, activated carbon, specific ion-exchange resins.
• Piping: Stainless steel or food-grade PVC/HDPE for water distribution.
• Bottles: Food-grade PET (Polyethylene Terephthalate) for clear, lightweight, shatter-resistant bottles. HDPE for larger containers.
• Caps: Food-grade polypropylene (PP) or HDPE.
• Seals & Gaskets: Food-grade silicone or EPDM.
• Plant Structure: Non-corrosive and easily cleanable materials for walls and floors to maintain hygiene standards.
