STA225-2189 is manufactured as an equivalent, direct replacement, alternative, analog, retrofit and analogue to replace DuPont DOW IP-77XP (IP77XP) UF membrane module.
STA225-2189 membrane modules are pressurized integrated modules, which are designed and manufactured for the filtration of surface water, potable water, seawater, industrial wastewater, and municipal sewage. These UF modules are made of upgraded new generation PVDF hollow fibers with extra permeability.
These UF modules can be applied in new systems, as well as directly connect to the existing UF systems as replacements, providing high-quality filtrate by removing suspended solids, colloids, pyrogens, bacteria, viruses, and other impurities to protect downstream processes.
Brother Filtration manufactures and offers all kinds of Ultrafiltration equipment for water treatment. Our new IP-77XP retrofit is especially suitable for applications such as municipal water, portable water, surface water, beverage clarification, industrial wastewater, reclaimed water reuse, and pre-treatment of seawater desalination.
The strong IP-77XP with perfect design has longer service time and more powerful capability. Also, when compared with the same dimension UF equipment, it needs less energy. It would be a high-efficient choice for your ultrafiltration.
It is the superb UF product, Brother Filtration newly launched. The IP-77XP is a powerful and practical UF filter, which can handle diverse conditions. We believe it will beyond your expectations.
