Dairy dedicated sanitary NF with 32mil runner, intercept milk fat & casein macromolecules, allow lactose & mineral salt permeation, realize integrated dairy grading, skimming & concentration.
Characterized by moderate working pressure and low energy requirements, nanofiltration acts as a cost-efficient solution dedicated to softening, organics separation and partial desalination within hygienic production setups.
Enhanced polyamide active layer boosts salt retention and sustains stable flux performance. The parallel flow channel structure delivers improved cleaning effectiveness. Wide tolerance to pH cleaning conditions allows highly flexible operation.
