Cross Flow – Non Submerge MBR Membrane

Cross Flow – Non Submerged MBR (Membrane Bioreactor) membranes are a type of filtration membrane configuration used in wastewater treatment processes. Unlike submerged MBR systems where the membranes are fully submerged in the wastewater, cross flow non-submerged systems utilize a partial submersion or non-submersion approach. Here’s an introduction to cross flow – non-submerged MBR membranes, along with their working principles and advantages:

Introduction

Cross Flow – Non Submerged MBR membranes are designed to operate with a partial submersion or non-submersion configuration. This configuration allows for a controlled flow of wastewater across the membrane surface, facilitating the separation of solids, microorganisms, and contaminants from the treated water.

Working

In a Cross Flow – Non Submerged MBR system, the wastewater flows tangentially across the membrane surface, creating a cross flow filtration mode. The membranes, which are typically flat sheet or hollow fiber configurations, act as a physical barrier. As the wastewater passes over the membrane surface, suspended solids, bacteria, and other contaminants are retained while the treated water or permeate flows across the membrane and is collected for further use or discharge.

To maintain the efficiency of the process and prevent fouling, the system relies on periodic backwashing or air scouring to remove accumulated solids from the membrane surface. The backwash or air scouring action helps to minimize fouling, maintain permeability, and ensure continuous filtration performance.

Benefits of Tubular UF Membrane Modules

Unlike outside-in filtration, as seen with submerged membrane technology, our robust tubular UF (ultrafiltration) membranes enable operators to sustain higher flux rates with less frequent cleanings and reduced maintenance. In addition you get:

Z

Higher flux and output

Z

High quality permeate ideal as pretreated feed for RO systems

Z

Fouling-resistant membranes due to crossflow filtration

Z

Less frequent cleaning resulting in reduced chemical costs

Z

Decrease in system downtime

Z

More robust membranes that are less susceptible to breakage

Z

The best ultrafiltration membrane filter

Ultrafiltration Membrane Filters Specification

5 mm Membrane Modules

5 mm Membrane Modules

The 5 mm inner diameter of the tubular membrane modules from Blufox Membranes are excellent in treating low-strength wastewater and effluent
streams that contains a low amount of solids.

8 mm Membrane Modules

8 mm Membrane Modules

The 8 mm inner diameter of our high-solids tubular membranes makes them ideally suited for high-strength wastewater treatment and effluent
streams while maintaining superior fouling resistance.

CR Membrane Modules

CR Membrane Modules

The superior robustness of Blufox’s CR membranes enable them to exhibit impressive resistance to a wide variety of chemicals and pH values (2–12), making them ideal for applications with high- trength influent.

Happy Clients

I have been working with Blufox for 2 years now, and I am glad I chose them from the beginning. Their products are of very high quality, and my clients have never complained about their products. Besides MBR membranes, they also have other good quality products, such as water pumps and air blowers, which suit my projects well. So if possible, I suggest you try their other products as well.
