What are the applications of different types of rotary drum screen?

In the field of water treatment, it is crucial to choose the right filtration equipment. The following briefly introduces the differences and applications of two common rotary drum screens-internally fed rotary drum screen and externally fed rotary drum screen.

1. Internally fed rotary drum screen

Working principle: The liquid to be treated enters the filter from the inside and is separated by the filter medium. Solid particles are trapped on the surface of the filter medium, while the clean liquid is discharged through the filter medium.

Use scenario: Suitable for occasions where a small flow rate needs to be processed and high filtration accuracy is required, such as laboratory analysis, pharmaceutical manufacturing, etc.

Advantages: Small footprint, easy installation and maintenance, suitable for processing high-concentration suspended solids.

2. Externally fed rotary drum screen

Working principle: The liquid to be treated enters the filter from the outside and is separated by the filter medium.

Use scenario: Suitable for occasions where a large flow rate is processed and low filtration accuracy is required, such as municipal water supply, industrial cooling water circulation, etc.

Advantages: Strong processing capacity, suitable for large-scale industrial applications, and low maintenance cost.

Whether it is an internally fed rotary drum screen or an externally fed rotary drum screen, they play an important role in their respective fields. Choosing a filtration equipment that suits your needs will help improve production efficiency and product quality.
