RFF/RFM/RFI SERIES ROTARY DRUM FILTER
Rotary drum filter is an outstanding and environmental friendly filtration equipment in recirculating aquaculture. Untreated water is gravity fed to the inside of the drum which has fine screens mounted to its periphery. The water flows through the screens while the solids are trapped by the filter screens, the filtered water flows outof the filter by gravity.
The drum filter is a static filtration system. As the accumulation of solids in the filter screens reduces the filtration efficiency and causes the water level in the drum rise, backwash will be triggered,the solids trapped on the filter screens is flushed into the waste tray and pushed out.
Application:
•Primary and secondary filtration for sewage and water treatment.
Circulating water treatmentor source water treatment inaquaculture.
•Municipal sewage treating system.
Features:
• International top design and configuation, high efficiency filtration, low power consumption and minimal maintenance.
• Modular filter panels, for easy installation and replacement.
• Automatic backwashing when the water level rises due to excessive contamination, saving energy and reducing consumption.
• Use of high pressure backwash (0.6MPA) and low flow nozzle(0. 8LPM).
Effective filtration, the backwash process is activated for just 1 minute every 10 minutes on average. (adjustable subject to TSS level of water).
• Superior to traditional sand filter, effective filtration up to 21 microns (700 mesh).
• Full 6063 aluminum alloy drum, 316L stainless steel frame.
• PLC control and connection to a control centre is optional.
RFF/RFM/RFI SERIES ROTARY DRUM FILTER
Static rotary drum filter
• Energy saving: Start backwashing only when the water level inside the drum rises due to excessive dirt.
Water saving: The filter mesh is backwashed with high pressure (0.6MPa/600kpa) and low flow nozzle of 0.8LPM.
• Under effective filtration, an average of 1 minute of backwashing is started every 10 minutes.
200 mesh (80microns) to 625 mesh (20 microns)modular filter panels, effectively transfer solids to the backwash position.
High efficiency backwash nozzle, specially designed sewage water collection tray, ensuring complete collection of backwash sewage, equipped with manual high-pressure backwash function.
