FILTRATION QUALITY

The worldwide bottled water market continues to grow and in 2018, was valued at $198 billion USD. Growth is expected to be $215 billion by 2025. By volume, the market was 391 billion liters in 2018 and is expected to reach 430 billion liters by 2025.

The increase in demand for bottled water has also increased the demand for higher quality products, free from harmful bacteria and chemicals. In recent years, this is a reoccurring issue for bottled water manufacturers, as source water used to produce their products has been decreasing in quality.

With the challenges being faced globally among manufacturers, the need for efficient and effective filtration systems has become a crutial component to delivering quality products that are safe and meet consumer demand. Bottled water consumers are also adopting new products with added health benefits in the form of minerals, oxygen, and vitamins which creates an added layer of complexity and need for advanced filtration solutions.

In addition, governing bodies such as the FDA, EPA, International Bottled Water Association and EU Directives, set standards that must be met in order for manufacturers to produce and sell products.

Filtration systems and strict process controls provide processors with the necessary means to meet or exceed the standards set for products they manufacture. Due to the regulations, bottled water producers rely on different grades of filters that are proven to retain microbial contaminants while maintaining the safety, quality and true nature of source water.

Source water varies from site-to-site and has an impact on the filtration process and the required steps to ensure, therefore impacting the filtration process and the steps required to ensure the water meets quality standards. From a microbiological and chemical standpoint, water is a sensitive product. It can be difficult to produce a quality product free from harmful microbial contaminants. It is important to consider filtration solutions and media compositions that are best suited to facility-specific challenges.

FILTRATION PROCESS

Sediment, Particulate & Trap Filter Stages: 1, 2, 3, 7

Pleated PolypropylenePP, PPE, HF Series

Pleated MicroglassFG, FGE Series

Polypropylene MeltblownGWTB, GCTB, GATB Series

Protecting the RO or Ion Exchange Units (IEU) is critical. Surface or ground water is typically treated and softened before fi ltration with a fi lter that removes particles larger than 10 microns, then fi ltered down to one or fi ve microns fi lter to protect the RO and Ion Exchange Unit.

Tank Filter Stages: 4 & 8

PTFE (Hydrophobic) Membrane GGPTFE Series (General Grade) PPTFE Series (Sterilizing Grade)

Polysulfone (Hydrophobic) Membrane PSH Series

Storage tank vent fi ltration allows for bacteria-free air to pass during fi lling and evac-uation, protecting the storage tank and its contents from contamination. This fi lter is typically rated at 0.2 micron, and is hydrophobic and bacterial retentive, which prevents moisture and bacteria from entering the tank.

Pre-Filtration Filter Stages: 5 & 9

Pleated Polypropylene PP, PPE, HF Series

Pleated Microglass FG, FGE Series

Removes fi ne particles and suspended organic matter and serves as pre-fi ltration to the deionization system and the bottling line. If water is treated with an IEU, a 5 micron fi lter may be installed between the IEU and the water storage tank to prevent fractured beads from entering.

Bio-Burden Filter Stages: 6 & 10

Polyethersulfone (Hydrophilic) Membrane GFPES Series (Food & Beverage Grade) BRPES Series (Bio-Burden Reduction Grade)

Reduces biological contaminants and serves as fi nal fi ltration before the bottling line, utilizing pre-fi lters ranging from 1 to 10 microns.

Gas Filter Stages: 11

PTFE (Hydrophobic) Membrane GGPTFE Series (General Grade) PPTFE Series (Sterilizing Grade)

Polysulfone (Hydrophobic) Membrane PSH Series

Serves as fi ltration during the bottling and packaging stage where C02 or N2 is present. Typically rated at 0.2 micron, this fi lter is hydrophobic and bacterial retentive to prevent moisture and microorganisms from contaminating the fi nished product.

This schematic should be viewed as a general example of where fi ltration systems could be located within a fermentation process. These processes will vary between companies and facilities. As such, each application should be reviewed and considered individually in order to choose the correct system technology.

FILTRATION MEDIA

While the general bottled water process is similar among manufacturing locations, each process is unique and demands specific filtration requirements and specific process considerations.

Differences in Processes & Product

Producing bottled water can be very different from one manufacturer to another which requires a variety of levels and types of filtration solutions. The following are several common types of bottled water produced today:

• Spring Water: Sourced from a natural underground formation and must flow naturally to the earth’s surface or through a sanitary bore-hole.

• Purified Drinking Water: Processed to remove chlorine and a majority of dissolved solids, such as magnesium. The source is not required to be named unless it is untreated public source of water.

• Mineral Water: Typically from a spring, this water contains dissolved solids such as calcium, magnesium, sodium, potassium, silica and bicarbonates.

• Seltzer Water: The FDA regulates this as a soft drink, which means rules are less strict than those for bottled water.

It is estimated that the bottled water industry will reach USD 215 billion by 2025.

Choosing the Right Media for your Process

When considering filtration media, several factors must be considered including: product specifications, required flow rates, influent quality and chemical compatibility. For example, polypropylene is FDA compliant and there are limited compatibility concerns when filtering water, but the other mentioned factors are vital to ensure suitable production of quality products that are safe for consumers.

One factor to consider is influent quality. There must be adequate coverage of the filtration area, or EFA, in order to capture the bulk of incoming solids. Depending upon the particulate distribution, and ambient conditions, coverage can be accomplished with a depth or pleated depth filter.

Once the majority of the solids have been removed, the focus shifts to the capabilities of the bottling equipment including the required end product quality specifications. In the bottled water industry, the accepted final filtration step is to polish with a 0.2um membrane cartridge. The type of membrane chosen is typically determined by the specific microorganisms present and the required retention claims predetermined by the bottler and regulatory agencies.

Ensuring adequate flow to the bottling equipment is an important consideration. If a filter is undersized or the incorrect media is chosen at any stage, the bottling equipment can be starved, which can lead to unexpected delays or complete shutdown.
