AQU-90 UF Membrane – Compact Ultrafiltration Hollow Fiber Filter

The AQU-90 UF Membrane is a compact ultrafiltration element designed to improve water quality in both domestic and small commercial water systems. This UF filter uses hollow fiber technology to retain suspended solids, bacteria, and larger particles, while allowing clean water to flow through.

Because it operates at low pressure, this ultrafiltration component delivers reliable performance without high energy use. Also, its simple physical separation method does not require chemical dosing, which keeps maintenance straightforward and cost-effective.

How This Hollow Fiber Filter Works

In typical water filtration setups, feed water enters the system and flows through the bundle of fine hollow fibers inside the UF module. Each fiber has extremely small pores that trap contaminants such as suspended solids and microbes. Meanwhile, clean permeate passes through the fiber walls and exits for use.

This makes the membrane ideal for applications where water clarity and pathogen reduction are priorities. Additionally, because the filter works at low pressure, it remains energy-efficient compared to higher-pressure systems like reverse osmosis.

Benefits of Using This UF Membrane

  • Removes bacteria and suspended solids to improve water clarity
  • Hollow fiber design increases surface area for consistent flow
  • Works at low pressure, which reduces energy demand
  • Suitable for both home and small commercial water systems
  • Helps protect downstream filters and purification stages
  • Easy to install and maintain with regular flushing

Applications for the AQU-90 UF Membrane

This compact hollow fiber filter is ideal for:

  • Domestic water purification systems
  • Small offices and residential buildings
  • Pre-treatment before fine filtration or RO stages
  • Cafés, clinics, and light commercial water lines

Because it removes larger particles and microorganisms, it enhances water quality and protects subsequent purification stages.

Installation and Care Tips

To get the best from the AQU-90 UF Membrane, install it in a compatible housing that suits your water system. Make sure to use appropriate pretreatment to remove excessive solids that might clog the membrane prematurely.

Periodic flushing or cleaning — depending on your system design and water conditions — will help maintain flow rates and extend membrane life.

Why Choose This Ultrafiltration Component

The AQU-90 UF Membrane stands out for its compact size, efficient ultrafiltration, and ease of use. It’s a solid choice for anyone looking to improve water clarity and reduce microbial content without the expense or complexity of high-pressure membrane systems.
