What are the performance of SUEZ DL8040C30 nanofiltration membranes after implementation?

Mondo Health Updated on 2024-01-30

SUEZ DL8040C30 nanofiltration membrane is a high-performance nanofiltration membrane from SUEZ for a wide range of industrial and municipal water treatment applications. The membrane is distinguished by its unique three-layer structure, with a middle layer patented by SUEZ that aims to improve the film's resistance to contamination and smoothness, thereby reducing the deposition of contaminants on the membrane surface. Below, the blue film water treatment will introduce to you its performance after failure.

What happens when the membrane fails?

1.Degradation of filtration effect: The main function of SUEZ DL8040C30 nanofiltration membrane is to intercept suspended solids, microorganisms, organic matter and other pollutants in the water, and when the membrane fails, the retention rate of these pollutants will be significantly reduced, resulting in the quality of the treated water not meeting the expected standards. In particular, the rejection capacity of substances with molecular weights in the range of 150-300 daltons is significantly reduced. This requires timely inspection and maintenance of the membrane by the operator to restore its filtration effectiveness.

2.Increased turbidity of water: This is because suspended solids and particulate matter cannot be effectively removed from the water after the membrane fails, leaving these substances in the treated water, resulting in increased turbidity in the water. This not only affects the taste and appearance of the water, but can also have an impact on the subsequent water treatment process, such as increasing the burden on the subsequent treatment unit and reducing the overall treatment efficiency.

3.Aggravation of membrane fouling: Under normal circumstances, SUEZ DL8040C30 nanofiltration membrane has good anti-fouling performance, but when the membrane fails, its anti-fouling ability will be weakened, and it is easy to be adhered and accumulated by pollutants. This further affects the filtration effectiveness of the membrane, creating a vicious cycle. Therefore, it is crucial to carry out regular cleaning and maintenance of the membrane to prevent the intensification of membrane fouling.

4.Increased operating pressure: This membrane operates at a lower pressure to reduce energy consumption and extend the life of the membrane. However, when a membrane fails, it may be necessary to increase the operating pressure of the system in order to achieve the same filtration effect, which not only increases energy consumption, but also may cause a greater load on the membrane, accelerating its failure.

5.Safety implications: SUEZ DL8040C30 nanofiltration membrane acts as an important barrier in the water treatment process, preventing the penetration and transport of harmful substances. Once the membrane fails, these harmful substances may pass through the membrane, affecting the subsequent treatment unit or effluent quality, and may even pose a potential risk to human health.
