Worldwide multinational businesses and local producers of bottled water brands have teamed together with Brother Filtration for years to successfully meet their quality and production criteria.

Every bottled water manufacturing process varies from factory to factory depending on the type and branding of the finished bottled product, the regional laws of the target market, and the source of the water itself.

These variations affect the filtration systems’ performance expectations and lead to a variety of approach options.

We aim to provide value-added filtering solutions that adhere to our application-led philosophies of enhancing process efficiency and minimizing waste by comprehending the unique requirements for each stage of the manufacturing of bottled water.

For final stabilization

Since it serves as the last line of defense against microbial contamination before packaging, this application is referred to as “critical.”

Our products’ membrane filtration will successfully eliminate any contaminating organisms from the water while preserving the cleanliness and vital elements that contribute to the water’s distinctive qualities.

The classification of bottled water and the local laws governing the exploitation of the source water should guide the choice of filters at this point.

Our R&D technical support team can assist in the verification of the optimum grade of the filter either through laboratory trials, or in-line performance assessments.

According to our experience, 0.2µm or 0.5µm grade filters are both suitable for this application all over the world. 0.2µm filters are sterilizing grade filters that have undergone rigorous validation and produce sterile effluent.

Brother Filtration filters are classed as high-standard and can effectively remove contaminating organisms from the water, to ensure product safety whilst complying with EU legislation.

A verified Cryptosporidium removal filter may be necessary for some producers of bottled water. Additionally, Brother Filtration offers suitable filters that can deliver a variety of retention efficiencies in either a depth format or membrane integrity tested style.

For final stabilization

For Pre-stabilization

 Pre-stabilization filters’ main purpose is to prevent colloidal particles from getting into the final membrane filters.

Most waters have a significant amount of suspended particulates moving in solution while visually appearing to be clear. Colloids are what they are known as, and they are often sub-micron-sized.

These colloidal species mostly consist of ions (Fe3+) that have leached into the water from a source connected to organic material.

The removal of these tiny, suspended particles prior to membrane filtration will increase the service life of the membranes and save long-term operating expenses because they are the primary cause of membrane filter blockage.

Interim storage may be required as the product water goes through the bottling operation. Pre-stabilization filters will lower the amount of microorganisms that reach the storage tanks, hence decreasing the possibility of biofilm development.

The facility’s ability to restrict microbial growth will improve the performance of the final stabilizing filters used before bottling and create a more hygienic processing environment.

For clarification

Water entering a bottling plant straight from a source is frequently referred to as the point of entry (POE), and before it enters intermediate storage, it must undergo clarifying filtration to get rid of any insoluble pollutants like sand, silt, or debris.

The filter used to meet this need will typically be built to handle a high and varied particle loading.

The performance of further downstream filtration and total process efficiency will be significantly influenced by the retention and construction of the filter at this point in the process, which should be carefully chosen.

Adsorptive carbon filtering of the water can be used to minimize any chlorine or chemical taints that could otherwise impair flavor or produce precipitation concerns if chemical alteration of the source water is allowed (for anything other than natural mineral water).

To catch any carbon fines that enter the process when using a carbon granule filter, a trap filter is needed downstream.

Backwashable clarifying filters from Brother Filtration offer an effective method of removing particles when unstable components like iron and manganese cause the precipitation of microscopic particles.

For sterilization of gases

Compressed gases that come into direct touch with any of the following items—product ingredients, the final, packaged product, packing materials, storage containers, or production equipment—are referred to as crucial and call for sterile filtration to prevent microbial contamination.

Compressed gases are typically used by filling machines at some point throughout the bottle filling process, whether for bottle formation, bottle rinsing/drying, or product pushing. To avoid microbiological contamination from endangering the packaged finished product, the gases will need to be sterilized.


Bottled water is something close to our daily life, it is a normal and ordinary thing we drink or use every day. But to produce bottled water is not an easy thing. High sanitary grade and high quality must be taken into consideration.

Brother Filtration helps bottled water producers to solve the filtration problem in the whole production process. We serve them for filtration solutions, and they serve us with pure and safe bottled water.

Our filters cartridge like PP melt blown filter cartridges, PP pleated filter cartridges, and PES pleated filter cartridges are suitable for bottled water application.
