Filter cartridges suitable for packaged water processes

Below is a sample production process for packaged drinking water.
Source: Application example provided by ROKI.
(This is for reference only; individual drinking water production processes may vary slightly.)

Raw Water >>> Primary Filtration (Grit Removal) >>>Storage Tank
>>> *** >>> Activated Carbon (Organic Matter Absorption/Odor Removal)
>>> Pre-Filtration (Small Particle Removal and Activated Carbon Particle Removal) >>>Storage Tank

***Due to slight variations in water quality across Taiwan, some customers add resin to the pre-activated carbon filter to adjust its hardness.

Heat sterilization >>> Final filtration (removal of particles smaller than 1µm) >>> storage tank >>> Filling

***Packaged drinking water can be sterilized using heat sterilization to remove microorganisms.

Filtration products used at each stage

Primary Filtration (Grit Removal) >>> A wide range of filter options are available, including primary filter bags, spiral wound filter cartridges, and deep filter cartridges to achieve the desired effect.
Activated Carbon >>> Mainly functions to adsorb organic matter and remove odors.
Adsorption efficiency varies depending on the carbon source.
Resin (Cationic and Anionic Resins) >>> Mainly functions to adjust the hardness of water.

Final filtration (removal of particles smaller than 1µm) >>> It is recommended to use a pleated filter element. Depending on the product requirements, you can choose a fiber or membrane filter.

Other Places Where Filters Are Used

Temporary Storage Tanks >>> To prevent dirty air or suspended microorganisms from entering the tank, an air filter (or air valve) is typically installed here.

Filling Area >>> Use clean air to clean the filling bottles.

It is recommended that the filters in the above locations use hydrophobic PTFE membrane filters. If you would like to know why, please contact DEOVOS Sales for further discussion!
