Product Description

Rotary Vacuum Drum Screen Filter for Aquaculture
Product Description
The Stainless Steel Irragation Rotary Drum Filter for waste water  is a mechanical, self-cleaning filter that works with gravity to prevent particle fragmentation. The filtering process of Drum Screen Filter is very simple, yet very efficient and reliable due to its overall design and operation. Drum Filters are designed with few moving parts to ensure a long life with low operating/maintenance cost.

Working Principle

The polluted water inputs the drum filter through the water inlet pipes, flows into the boxes, and then into the interior of the filtering drum. The filtering drum is covered with a V-slot micro mesh, all particles bigger than the filter mesh will stay inside the drum filter.

The waste particles will slowly block the filter mesh, makes it hard for the water through the mesh, which leads to a lower water level in the clear water chamber of the filter. Once the water level dropped to a minimum level-indicated by sensor-the controller starts the washing process. The process contains the rotation of the filter drum by a geared motor and multiple nozzles spraying water with high pressure to the outside of the filter mesh. The waste clogged the filter mesh is flushed into the waste tray, and then leaves the filter by wastewater discharge through waste outlet.
V-slot Features
Slot Section

The Continuous slot screens are made of V-shape wire or wedge shape wire around an internal array of longitudinal support rods. Each jointpoint of these wire is fusion welded, the V or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening. Therefore the screen allows water or oil to enter the well freely in ample quantities while  keeps the majority of sand and gravel out of the well at the same time.

Continuous slot: support rods and longitudinal wire makes an opening which significantly increase the available opening area, and allow better access to the water flow.

High open area: reduce the water level, thus to save energy consumption. Meanwhile, high open area can make the groundwater enter the screen much slower than  other filtration apparatus, which can avoid sand from entering screen due to high pressure, hereby lowering pump wear down.

High Strength: It takes stainless steel as main raw material, then is welded at high temperature, which guarantee high strength to bear big water pressure, hereby it has long life span.
