One of the best industrial drum filters. Detailed overview of a drum filter for wastewater treatment

ASSIGNMENT OF THE BFL DRUM FILTER:
The mechanical drum filter is a self-cleaning filter of various capacities with a wide range of adjustments for clarification of fluids. The use of drum filters is an effective and reliable technology for separating mechanical particles from liquids. The size of the separated particles in the filtration process is in the range of 40 - 100 microns (i.e. 0.04 - 0.1 millimeters).
ADVANTAGES OF BFL DRUM FILTERS:
- Effective filtration, it’s up to 75% for solid impurities;
- High efficiency and reduced wash water consumption;
- Continuous operation,
- Automatic filter flushing without stopping the filtration process;
- Possibility of visual control of flushing;
- Reliable, leakproof 100% stainless steel construction;
- Full automation of technological processes that does not require an operator;
- Convenient operation and technical service.

APPLICATION OF BFL DRUM FILTERS:
BFL Drum filters are used where:
A high degree of purification in large volumes of water is required
Consistent filtrate quality is required
Interruption of the filtration process is undesirable
Requires high performance with small dimensions
A reliable, simple, easy-to-maintain filter unit is required
Areas of application for drum filters:
- Pre-filtration of water from surface sources before sand filters
- Additional treatment of industrial, rainfall and municipal wastewater
- In aquaculture, on fish farms, in recirculating water systems in a continuous recirculation mode
- Filtration of water in cooling systems in industrial heat exchange circuits used by cooling towers
- Filtration of water in recycling water supply systems
- Additional treatment of industrial effluents
- Purification of wash water at filtering stations, in order to return the treated wash water to the head of the structures.
Due to the fact that the drum filter uses the principle of a barrier, its filter meshes allow to retain and remove suspended particles larger than 40 microns from the water in a non-pressure mode.
The use of drum filters in industrial plants has its own characteristics:
- with an excessively large amount of contamination in the form of suspended solids (more than 200 mgl / l), the cascade principle is used, i.e. filters are sequentially installed with different filter meshes (from larger to smaller ones);
- when using drum filters for purifying petroleum products, it should be understood that filtration is possible, however, the service life of the filter mesh will be reduced and will depend on the aggressiveness of the medium.
