How our Stainless Steel Ultrafiltration System works

To understand the efficiency of our Stainless Steel Ultrafiltration system featuring advanced ultrafiltration tube technology, let’s take a look at the three-step filtration process:

  1. The feed pump introduces the material into the ultrafiltration (UF) modules.
  2. Within these modules, the material is circulated through the ultrafiltration tubes by recirculation pumps, with the option to arrange multiple modules in series for expanded filtration area.
  3. The filtrate permeates the tube walls into the module shell, exiting at the top, while the concentrated material is discharged through a flow control valve, ensuring efficient separation and purification.

What is an ultrafiltration tube?

An ultrafiltration tube is a component of water treatment systems that uses a semi-permeable membrane to separate particles and substances from water, enhancing purification and filtration processes.

How does a stainless steel ultrafiltration system work?

A stainless steel ultrafiltration system operates by pushing water through ultrafiltration tubes within a durable stainless steel framework, effectively removing contaminants and ensuring high-quality filtration for various applications.

What are the benefits of using a stainless steel ultrafiltration system?

The primary benefits include long-term durability, resistance to corrosion, high efficiency in filtering diverse contaminants, and the ability to handle high volumes of water, making it ideal for industrial and commercial water treatment.

Can the ultrafiltration tube technology handle industrial wastewater?

Yes, ultrafiltration tube technology is designed to efficiently process and purify industrial wastewater, removing solids, bacteria, and other particles to meet environmental standards and reuse criteria.
