Channel-Type Rotary Drum Screen for Fish Pond Filtration

The channel-type rotary drum screen is a highly effective solid-liquid separation device widely used in aquaculture applications, particularly for fish pond filtration. Designed to remove suspended solids such as fish waste, uneaten feed, and algae from the water, it plays a crucial role in maintaining water quality and creating a healthier aquatic environment.

This equipment operates continuously, with water flowing through the screen drum placed in a channel. As the drum rotates slowly, solid particles are trapped on the outer surface of the screen while clean water passes through. The trapped solids are then removed by an automatic backwash system, which uses spray nozzles to clean the screen surface based on a preset time interval. The interval and duration of the backwash cycle can be adjusted through the control system, which helps optimize performance and reduce water usage.

The channel drum screen features a simple mechanical structure, low energy consumption, and reliable operation, making it easy to install and maintain. It is suitable for both freshwater and saltwater applications and is especially beneficial in recirculating aquaculture systems (RAS) where high water quality standards must be maintained. The main components, including the drum and frame, are typically made of stainless steel (such as SS304 or SS316), ensuring corrosion resistance and long service life.

Overall, the channel-type rotary drum screen is an efficient and cost-effective solution for fish pond filtration, helping operators improve productivity, reduce environmental impact, and lower operational costs.
