mineral water plant
13Sep 2021

Ongoing water shortages are causing an increase in demand for water. Due to the limited availability of freshwater, governments find it increasingly difficult to provide fresh water to their populations. As a result, several firms have built mineral water facilities to get fresh drinking water.

However, the question arises, how do we get fresh mineral water? Bottling India discusses the working of mineral plants for the consumer to know, how do they get clean water –

CHLORINE DOSING SYSTEM

Living microorganisms and chemical compounds in raw water can foul a membrane and reduce its effectiveness. Due to its presence, the iron in water can be oxidized to ferric oxide settle down in the storage tank. We have a Hypochlorite dosage device available for this purpose. The raw water storage tank is dosed with a sodium hypochlorite solution of 3-4 ppm. Hypochlorite acids are formed when this chemical interacts with water.

Two dosing pumps are provided as well as one HDPE hypochlorite solution preparation tank. Isolation valves are used in the required suction/discharge pipework in PVC construction. Each patient’s dosage rate is modified according to their individual needs.

RAW WATER STORAGE TANK

For the storage of chlorinated water, one quantity of raw water is necessary. A PVC piping system, isolation valves, and an appropriate level indicator are installed in the tank’s interior.

RAW WATER SUPPLY PUMP

Stainless steel horizontal centrifugal pumps have been installed to deliver raw water to the Pressure Sand Filter Unit. There is also necessary suction and discharge piping in stainless steel with isolation valves up to the PSF Unit.

PRESSURE SAND FILTER

R.O. Plant feeds raw water via a series of filters. To remove suspended particles & turbidity from raw water, a Pressure Sand Filter Unit is provided. The PSF Unit is a Stainless Steel vertical pressure vessel (PSF Unit or PSF Unit). Inside, it is equipped with a bottom-collection mechanism. On top of the pebbles and gravels, uniform grades of silica quartz sand are placed. SS frontal pipework and a Multiport Valve are installed on the outside of the unit. A sand bed is submerged in water during a service cycle, trapping suspended debris and turbid particles. There will be more pressure drops and less flow when the sand bed becomes choked with suspended particles. It’s time to clean the filter bed at this point.

As soon as the pressure drop over the sand bed exceeds the required limit (0.5 kg/cm) or as soon as the quality of filtered water is determined, whichever comes first. Backwashing and rinsing of the Sand Bed are required for regeneration. Backwashing service water is fed in the opposite direction of the service cycle to loosen the filtering bed. Entrapped suspended matter is released due to this process, and it is discharged together with a wastewater sample. Backwashing continues for about 10 to 15 minutes, or until the effluent flowing out is clear. It takes around five minutes to drain the treated wastewater, making sure all the unclear water has drained away.

SMBS DOSING SYSTEM

For the same reason, we’ve installed a sodium metabisulphite dosing mechanism to prevent the membrane from oxidizing. The recommended dosage is 4-5 mg/liter. For this, an HDPE chemical preparation tank with a diaphragm-type electronic dosing pump is available.

ACTIVATED CARBON FILTER

Natural Water may contain various amounts of color, odor, chlorine, and organics, all of which are unsuitable for drinking and must be removed. For die-infection, raw water must be chlorinated before it can be fed to the RO system. In addition, chlorine is a powerful oxidizing agent, which destroys the membranes of the RO Water that is passed through a bed of activated carbon to remove chlorine, odor, and color. In this case, the higher surface area and particular characteristics to absorb organics make this Carbon Granule an excellent choice. ACF Unit is a vertical pressure vessel made of FRP material. There’s a filter at the bottom of the system. In the front of the unit, there is an SS pipework and an MPV on the outside. Coarse & Fine Silex is loaded with granular activated carbon. Chlorine and odor are removed from the water passing through the Carbon Bed throughout the service cycle.

Whenever the pressure drop across the Carbon Bed exceeds the stated limit of (0.8 kg/cm) or when the quality of the filtered water deteriorates, the device is shut down for regeneration. As part of the regeneration process, the Carbon Bed has to be backwashed and rinsed. Over time, carbon’s life is depleted, which may be verified in a laboratory. For this use, the iodine content is crucial. Carbon is typically changed once a year.

ANTI SCALENT DOSING

A concentration of calcium and magnesium hardness salts that exceeds their solubility limit is likely to precipitate and damage membranes, resulting in scaling and poorly treated water quality from RO systems. There is a scale inhibitor dosage method to prevent this from happening. Standard practice is to add a scale-inhibitor, such as Perma care 191, to feed water. The recommended dosage is 4-5 mg/liter. For this, an HDPE chemical preparation tank with a diaphragm-type electronic dosing pump is available.

MICRON CARTRIDGE FILTER

If you’re looking for a Micron Cartridge Filter that comes with Nominal & Absolute Nominal and Absolute Nominal and Absolute Micron Cartridge, you’ve come to the right place. It would help if you changed this Cartridge after a certain number of days of use. As your product water passes through the following filtration process, there is a potential for particles to get through. However, the Cartridge filter will halt any bacterial growth as small as 0.2 microns.

HIGH-PRESSURE PUMP

A higher water supply pressure is required for the Reverse Osmosis Process to work. RO provides a vertical multistage centrifugal high-pressure pump in stainless steel for this purpose. The operating pressure for the system is 14-16 kg/cm. SS discharge pipework and appropriate control valves are installed on a high-pressure pump system.

REVERSE OSMOSIS SYSTEM

Using the ‘Osmosis’ principle, the Reverse Osmosis System rejects 97 to 99 percent of total dissolved solids. RO Module assembly placed on MS Skid. Spirally wound membrane components are housed in sequence in a high-pressure FRP Pressure Vessel.

There are two streams of soft water used in RO systems: Product and Reject water. As a result of treatment, product water has a lower TDS level. A high-concentration liquid that should be drained rather than re-used is known as “reject water.” First, high-pressure feedwater is supplied into the first pressure vessel, and then the treated water is collected in the center core tube. The treated water from each membrane is collected using a shared product water storage tank, and the rejected water is discharged.

PRODUCT WATER STORAGE TANK

Stainless steel horizontal centrifugal pumps have been installed to deliver raw water to the Pressure Sand Filter Unit. There is also necessary suction and discharge piping in stainless steel with isolation valves up to the PSF Unit.

WATER SUPPLY PUMP

The Mineral Adding System is supplied with water via a stainless steel pump.

ADDED MINERAL SYSTEM

To improve the taste of R.O.Product water, which has a low TDS value. Mineral Adding System or Blending System enhances the flavor of the water by adding minerals to it. A stirrer will combine the physical mineral in the mixing tank, and a dosing pump will add it to the RO water before ozonation using the TDS controller. TDS may be adjusted with a Blending system by adding Filtered water after ACF has been properly treated.

However, this type of blending system is simple to operate, and it will automatically adjust TDS in re-use products (RO).

ABSOLUTE MICRON CARTRIDGE FILTER

The water will next be passed through the 1 and 0.2 m Absolute-Micron cartridge filter after the Mineral Adding process to remove fine micron contaminants.

After Ozonation, the Sanitary Housing and Filter will ensure that the treated water is of the highest quality.

Bacteria and viruses will also be addressed.

It’s made of stainless steel (SS-316) and consists of a pleated PP cartridge.

ULTRAVIOLET STERILIZER

RO treated water is devoid of micro-biological contaminants such as Bacteria, Viruses, etc. However, they may reappear in water after lengthy storage. Reverse Osmosis Application is required for water disinfection before filling and sealing the bottle. To disinfect RO-treated water before filling pre-cleaned PET bottles, an online Ultra Violet Sterilizer is offered. Ultra Violet Rays are used to destroy germs by passing the water through UV Tubes that emit high-intensity Ultraviolet Rays. Ultraviolet Lamps are installed in a stainless steel surface housing, finished with a brushed stainless steel finish.

OZONE GENERATOR

The RO system rejects all micro-organisms such as bacteria and viruses, but they may grow in sealed bottles over time after passing through the UV system. Because of this, sanitizing Reverse Osmosis (RO) water before bottling is very important. This is a must if you want to verify that your mineral water plant meets the required requirements. Your water will become Oxygen-Rich, and This Ozone Generator will prevent bacteriological Growth, which extends the shelf life of packaged drinking water bottles if it is not opened for a while. The ozonation of water may also enhance the flavor of your treated water by adding a sour flavor to it.

OZONE RE-CIRCULATING TANK

Water must be treated with ozone gas to get the required ppm. Ozone re-circulating tank: a flow rate-dependent pump re-circulates the water. A static mixer can be used to assist in mixing up the ozone. It has been equipped with only one product water transfer pump to the filling area and one recirculation pump to fill this tank.

Packaged drinking water has the following advantages:

  • If your primary water source fails or gets polluted, you’ll have a backup supply of clean water to drink.
  • This is a convenient supply of clean water that may be consumed outside the house.
  • Bottled water may taste better than untreated tap water since it does not include chlorine and may have a combination of minerals to increase flavor.
  • It’s safe to say that untreated tap water has more pollutants than most bottled water
