UNA-600A UF Membrane Asahi Kasei Microza Equivalent

Product Introduction

The UNA-600A Ultrafiltration (UF) Membrane Module is a premium-grade filtration solution engineered as a fully compatible and high-performance equivalent to the renowned Asahi Kasei Microza UNA-600A. Developed for water treatment systems that demand reliability, consistency, and ease of integration, this module enhances both new installations and retrofits.

Using advanced hollow fiber membrane technology crafted from polyethersulfone (PES), the UNA-600A provides superior removal of suspended solids, bacteria, macromolecules, and colloids. It supports a wide range of applications including potable water production, wastewater reuse, reverse osmosis (RO) pretreatment, and industrial process water management. Reliable, efficient, and cost-effective, the UNA-600A delivers best-in-class performance.

Working Principle

The UNA-600A UF membrane module works via an outside-in flow configuration using PES hollow fiber membranes.

Filtration Process:

1.    Feed Water Introduction
Raw or pretreated water enters the module and flows over the exterior of the hollow fibers.

2.    Filtration
Water permeates through the membrane walls (with nominal pores of 0.01–0.03 µm), while contaminants such as turbidity, bacteria, and viruses are retained on the outside surface.

3.    Permeate Collection
Filtered water enters the lumen of each fiber and exits via the permeate outlet system.

4.    Membrane Cleaning
To maintain optimal performance, the system employs air scouring, backwashing, and chemical cleaning-in-place (CIP) as required.

This configuration ensures uninterrupted filtration with minimal fouling, high water recovery, and consistent permeate quality under varied operating conditions.

3.    Wastewater Reuse
Supports advanced tertiary treatment for non-potable use such as irrigation, cooling, and toilet reuse.

4.    Industrial Process Water
Used in electronics, pharmaceuticals, food and beverage, and other manufacturing sectors.

5.    Cooling Towers & Boiler Feed
Reduces particulates and microbes, protecting equipment and improving efficiency.

6.    Desalination Plant Pre‑Filtration
Serves as a robust first-step membrane to protect SWRO units from solids and biofilm.

FAQ

1. Is the UNA-600A fully compatible with Microza systems?
Yes, it offers exact physical and hydraulic compatibility as a direct replacement for Asahi Kasei Microza UNA-600A.

2. What pore size does this membrane have?
The module features a nominal pore size between 0.01 and 0.03 µm, ideal for pathogen removal and turbidity control.

3. How often should I clean the membrane?
Backwashing is generally performed every 30–60 minutes; CIP is recommended every few weeks to maintain performance.

4. What is the typical lifespan?
With proper maintenance, expect 5–7 years of reliable service.

5. Is it certified for drinking water use?
Yes, it is NSF/ANSI 61 compliant and suitable for municipal potable water applications.

6. Can it handle turbid or variable source water?
Absolutely—PES fibers offer robust fouling resistance under variable feedwater conditions.

7. What cleaning chemicals are supported?
Compatible with acids, alkalis, and disinfectants such as sodium hypochlorite, citric acid, and sodium hydroxide.

8. How scalable is the module?
The compact design supports modular installations; multiple units can be combined to match any capacity requirement.

Conclusion

The UNA-600A UF Membrane Module, fully equivalent to Asahi Kasei’s Microza product, delivers unmatched performance and reliability. Its use of PES hollow fibers, high microbial retention, low-pressure operation, and robust cleaning capabilities makes it an excellent choice for municipal, industrial, or commercial water treatment projects.

Engineered for ease of integration, certified for safety, and designed for sustainable operation, the UNA-600A is the perfect UF module for modern water treatment systems where quality, durability, and efficiency matter most.
