Masterfilter APKV is a pre-stabilisation filter has been developed for the reduction of microbial and colloidal contamination in the processing of bottled and mineral water and also protecting the service life of the final membrane filters. Constructed from a unique multilayer of Polypropylene and PVDF nanofibers, the absolute rated APKV filters offer high flow rate and optimized graded density, facilitating the reduction of a range of microorganisms, colloids and polymorphous organic matter depending on the source of the water. The robust nanofiber media construction gives the filter high porosity and strength enabling the filter to perform with consistency and assurance.
