What is MF Membrane and How Does It Work?

In the field of water and wastewater treatment, the emergence of innovative technologies has revolutionized the way we purify and treat water. One such technology that has gained significant recognition is the MF membrane. In this blog, we will delve into the details of what exactly an MF membrane is and how it works its magic to provide clean and safe water for various applications.

Before we dive deeper, let's first understand what MF stands for. MF stands for Microfiltration, a process that utilizes a unique type of membrane to separate suspended particles and microorganisms from water. This membrane is known as the MF membrane.

At the forefront of MF membrane innovation is Jiuwu, a leading brand in the water treatment industry. With their advanced technology and expertise, Jiuwu has developed high-quality MF membranes that have gained global recognition for their effectiveness and efficiency.

Now, let's shed some light on the working principle of an MF membrane. The main purpose of the MF membrane is to act as a physical barrier, allowing the passage of water molecules while restraining larger-sized particles, colloids, and microorganisms. This process occurs through a combination of size exclusion and sieving mechanisms.

To elaborate further, the MF membrane contains an array of microscopic pores that have a specific size distribution. These pores are small enough to block impurities such as suspended solids, bacteria, and viruses, which typically have larger molecular sizes. However, they are large enough to allow water molecules and smaller ions to pass through, ensuring the desired level of water purity.

The four key steps involved in the functioning of an MF membrane are as follows:

Raw Water Intake

The water to be treated is introduced into the system, where it undergoes pre-treatment processes to remove coarse solids and other contaminants that may interfere with the MF membrane's operation.

Membrane Filtration

The pre-treated water is then pumped through the MF membrane module, where the suspended particles, colloids, and microorganisms are retained on the surface or within the pores of the membrane. This step effectively separates the impurities from the desired pure water fraction.


Over time, the accumulation of impurities on the MF membrane can lead to a decline in filtration efficiency. To mitigate this, a backwashing process is carried out periodically. Backwashing involves reversing the flow of water through the membrane module, dislodging and removing the trapped impurities, and restoring the membrane's performance.

Product Water Collection

Finally, the purified water that has successfully passed through the MF membrane is collected as the desired product. This water is free from harmful contaminants, making it suitable for various applications such as drinking water, industrial processes, and wastewater treatment.

In conclusion, the MF membrane, pioneered by Jiuwu, has revolutionized water treatment processes by effectively separating suspended particles, colloids, and microorganisms from water, ensuring clean and safe water for various purposes. With its unique design and efficient working principle, the MF membrane plays a crucial role in achieving sustainable and reliable water treatment solutions.
