Bottled Water Treatment Plants


Mineral water /drinking water/natural water/ spring water are terms used for the various bottled water being marketed in the world.

The main feature in all these types of water are that they are made more safe and reliable for the human consumption. They differ major in its source and the treatment being employed before bottling.

Water treatment for Mineral Water Bottling is completed in four phases.

1. Physical Appearance (Color, suspended material, )

2. Taste & odor, smell, gasses etc.

3. Salt Separation (Reductions/adjustments)

4. Bacteria / Virus Removal

At the first level, we are required to remove sand, dirt, clay, rust, and all other suspended particles from the water. For this purpose, we use cartridge filter, sand filter, bag filters, multimedia filter etc. to bring water quality acceptable for further processing.

The second stage involves the treatment by chlorination, and activated carbon filtration.

With this, water is made free from all organic chemicals, removes bad taste & odor, colour smell etc. With this the taste of water improves to an acceptable level.

The third phase depends on the quality of water available. Now the drinking water manufacturers are setting their TDS target to a suitable limit of 150 - 200 ppm. This can be accomplished by using either

1. Deionization / Demineralization plant

2. Distillation plant

3. Reverse Osmosis unit

All of these equipment can give you water having TDS < 5 ppm CaCO3. So to achieve the required drinking water standards you have to mix the appropriate minerals in this pure treated water or just mix the treated raw water (of acceptable quality) to bring TDS level within required range. These systems are also used if your feed water either has high TDS level or it contains some other toxic dissolved solids / metal as arscenic, cobalt, chromium, zinc, lead, asbestos, fluorides, nitrates/ nitrites etc.

Among all of the above three techniques, reverse osmosis systems gives the best results in compared on the basis of ease of operation, operating cost, maintenance cost, consistent product water quality, less trouble shooting required, etc.,.

The RO system should have pre-treatment systems as water softeners and carbon filters.

As pure water treated from all above techniques don't has a better taste. Furthermore the salts level is also reduced towards zero, we require some addition on minerals to increase water TDS to 150 – 200 ppm. This mineral balancing is done by dosing solutions food grade salts in the treated water

This phase will complete our salt reduction / adjustment portion of treatment.

The last and the most important phase of bottle water production is to remove / kill the bacteria & viruses from the water before filling to make it safe for human consumption. This also reduces that chances or microbiological growth upto expiry date of the product water. This can be accomplished by the following most common methods.

1. Chlorination

2. Ultra Violet Sterilization

3. Ultrafiltration (UF)

4. Ozone treatment

Chlorine is still used as the most important disinfectant for water treatment all over the world. However powdered and liquid chlorination increase the TDS, induces bad chlorine tastes. In addition, toxic chlorinated compounds may be produced during chlorination.

UV sterilization now a days along with ozone treatment is used to bring water upto European standards. This combine treatment is the most effective & reliable method to produce bacteria / Virus free water safe for any drinking application.

The dosage required for common bacteria range upward to more than 20,000 microwatt-seconds/sq cm. To allow for less than 100 percent transmission, a purification system should be designed to deliver 2537 A energy in excess of 30,000 microwatt-seconds/sq cm.

Ultrafiltration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron.  Typically, ultrafiltration will remove high molecular-weight substances, colloidal materials, microbes, bacteria and viruses, and organic and inorganic polymeric molecules.  Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed.  Because only high-molecular weight species are removed, the osmotic pressure differential across the membrane surface is negligible.

Now a days ultrafiltration systems are mainly used with all mineral water plant to reduce to microbe load.

Ozone is the most powerful oxidant currently in use for water treatment. Commercial generation equipment generates ozone at concentration of 1-3% in air (i.e., 2 - 6% in oxygen). Ozone is unstable in water, However, it is more stable in air, especially in cool, dry air.

To prepare an comprehensive proposal the client must finalize the following basic input

The water quality available for processing

Estimated Capacity of the mineral water plant

Expected quality of mineral water required

Filling requirements (Manual or Automatic)

Container sizes (1/2 lit, 1.5 lit, 3 lit, 10 lit, 5 gallons)

Water Bottling Systems

In addition to complete bottled water treatment plant Water 2000, Inc, Inc also supplies complete bottling system for varying capacities (0.6 lit, 1.5 lit, 3 lit, 12 lit and 5 gallons bottles) including

Rinser

Filler
