What is a drum filter?

The drum filter is a large, cylindrical machine that is usually used in industrial applications for filter fluid bearing a high concentration of suspended solids. The rotary filter of the drum works by drawing water through its external filter surface into the inner vacuum using an inner vacuum. The suspended solids in the water are captured on the drum surface and the filtered water is then pumped. Drum filters can use removable filter panels of the screen type or have a sieve of openings for use with filter coating on their surface. The drum filters have a minimum of moving parts and are cheap for operation and maintenance. The drum interior is equipped with a vacuum channel in the center and the pumping system for filtered water. Once the system is running, the rotating drum has a strong vacuum created in its interior, which will draw soil water from the bathtub through the filter element into its interior. Suspended solids are captured on the outer surface of the drum filter to be discarded or used by theObrost on their nature.

Filters

filters that use fine network panels are usually equipped with a spray system that, when the drum turns, is washed with the collected solids from the filter elements. This variant is commonly known as the Micro-Screen drum filter and is usually used in applications where solids are to be discarded. The micro-screen drum filter is particularly useful for cleaning water contaminated with coarser solids such as animal hair or feathers that would clog conventional filters. The filter panels will also be replaced after wear.

perforated drum filters are often used in water treatment, which remove a large amount of fine sediment from the water. They can also be used to remove waste water from the sustained porridge. These filters work on the same basic principle as the removable panel filters, but use a regularly applied filter layer to captureEntu. The drum is perforated with numerous holes that create a sieve similar to the outer surface through which the water is drawn. The drum is then covered with materials such as Diatomaceous Country or Perlite that perform the filtering process.

The drum filter rotates against a flexible plate or knife that scratched the captured sediment for later use or disposal. This knife removes a thin layer of filter aids and at the same time reveals a fresh, uncontaminated material to continue the filter cycle. This causes a gradual depletion of the filter layer, which requires regular re -coating the drum. Both types of drum filters are not only very effective in separating heavy, dense suspension, but can be cost effective due to the simplicity of systems.
