It is suitable for situations where the sewage quality changes greatly. The generally used methods are: sand filtration, activated carbon adsorption, flotation, coagulation sedimentation, etc. The characteristics of this process are that it uses hollow fiber ultrafilters for treatment. The pretreatment system mainly removes organic matter, suspended matter, colloids and residual chlorine in the water to ensure that RO can work normally. The treatment process uses multi-media filtration, activated carbon adsorption, and softener to reduce the scale, algae growth, microbial pollution and oxidants generated when RO is working.

[0003] However, it still has some disadvantages. For example, when the traditional ultrafiltration pretreatment device for recycled water reuse is in use, excessive accumulation of impurities and garbage in the sewage will settle to the bottom, requiring a lot of manpower and time to clean up. In addition, the traditional method of filtering sewage mostly uses alum precipitation for a period of time before being put into use.
