ROTARY MICRO FILTER

In demanding aquaculture applications, drum screen filters have proven to be highly efficient and reliable in removing solids from volumes of water large and small. Pentair Aquatic Eco-Systems is proud to offer our DSF Series™ line of drum screen filters, with a wide range of models, sizes and micron ratings to meet the specific needs of nearly any field application.

Featuring a field-proven design and the highest quality materials available, the DSF Series™ follow the simple, robust and time-tested principles of drum screen filter operation. Water containing solids enters the rotary drum in the front of the system. Water passes through the micro-mesh filter, which filters out solids (for increased durability, stainless steel wedge-wire filtration material is also available). As the filter mesh or wedge-wire material becomes increasingly loaded with solids, the water level within the drum increases to the point that it triggers the cleaning process. As the drum starts to rotate, the spraybar nozzles scour the filter mesh or wedge wire with high-pressure water, returning the screen to its original permeability. This allows the internal water level to drop and stop the cleaning process. Solids that are cleaned from the water are collected in a trough and transported away from the drum screen filter.

Channel Installed

PC models are installed directly into a concrete water channel. Water flows into the center of the drum and passes through the screen material. After filtration, the water is discharged into the downstream channel. This configuration is commonly is used in high-throughput, large installations, often with multiple systems in parallel.

Integrated Tank with Pipe Inlet and Outlet

CE models offer integrated tanks and inlet/outlet ports for connecting directly to pipes. Water flows through a pipe as it approaches the filter, then flows into the drum where it passes through screen material. After filtration, the water is discharged into a downstream pipe. These models rest on an integrated framework, and they do not require construction of concrete channels for installation. The flexibility of these models makes them suitable for a range of applications.

Hybrid Models with Pipe Inlet and Channel Outlet

Models with pipe inlet ports and channel outlets are like a hybrid: they feature an inlet port for connecting directly to pipes, while water leaves the filter by pouring into a channel. Water flows through a pipe as it approaches the filter, then flows into the drum and passes through the screen material After filtration, the water is discharged into the downstream channel.

     

DSF Series Drum Screen Filters

Our exclusive Wedge Wire technology uses precision-fabricated laser welded mesh to capture particles. The all-stainless design of the Wedge Wire screens is much more robust than standard poly mesh screens. For demanding applications, ask us about Wedge Wire technology for enhanced reliability and extended service life.

PRINCIPLE OF OPERATION

Liquid containing solids enters the rotary drum in the front of the system. Water passes through the micro-mesh filter, which filters out solids. As the mesh clogs with solids and sludge, the water level within the drum increases to the point that triggers the cleaning process. As the drum starts to rotate, nozzles scour the screen with high pressure water, returning the screen to its original permeability. This allows the internal water level to drop and stop the cleaning process. Solids that are cleaned from the screen are collected in a trough and transported from the system for further processing.
