Background

Although the traditional spiral-wound membrane module has high packing area density, the requirement on the quality of inlet water is high, and the pretreatment process is complex. Because organic pollutants, inorganic scaling substances and suspended particle impurities in the fluid can easily block a flow passage separation net of the roll-type membrane component, frequent shutdown and cleaning of the system are caused, the service life of the membrane column is shortened, and even normal operation cannot be realized.

The existing disc-type membrane component solves the pollution resistance problem of the membrane column. There are in fact two problems with disc-type membrane columns: firstly, disc type membrane columns for nanofiltration, ultrafiltration and microfiltration cause a large amount of pressure loss due to repeated violent water flow reversal of fluid, and the energy consumption of system operation is large; and secondly, the packing area density of the common disc-type membrane component is low, and the disc-type membrane component cannot be widely popularized and applied in the field of municipal sewage.

The existing disc type membrane component can reduce the pressure loss in the membrane column, namely, the power consumption cost is greatly reduced. Especially in municipal sewage processes, system recovery, investment costs and operating costs are the most important factors. Therefore, in the field of energy-intensive shapes, the anti-pollution membrane module with low pressure loss is well popularized in the market. However, in actual use, the use effect of the disc type membrane module still cannot meet the actual requirement, and a large lifting space still exists in the pressure loss and the filling area of the membrane, so that the disc type membrane module can be better accepted by the market.

In summary, there is a need for a reasonable improvement of the existing guiding and filtering device for disc membrane module.
