ip77xp

Overview

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.

Highlights

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.

  • Integrated design for easy installation
  • High-quality filtrate
  • Less energy is needed by extra high permeability
  • Longer service life by high fouling resistance and mechanical strength
  • Direct and economical module replacement

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.

  • Outside-to-inside flow direction
  • Upgraded new generation PVDF hollow fiber
  • Nominal pore size of 0.03 μm
  • Typical filtrate quality SDI ≤ 2.5, turbidity ≤ 0.1 NTU
  • Suitable for various applications
