Flootech Oy offer a wide range of Rotary Drum Filter solutions to treat various water sources for use in large scale cooling towers, municipal desalination plants and for industrial process water make-up.
The screening solutions can be used for fresh and seawater intakes. With installations dating back to the 1960’s, Flootech’s dual flow basket screens are industry proven, robust and offer clients with significantly lower total cost of ownership compared with traditional drum filters.
The Flootech Rotary Drum Basket Filters are designed to provide preliminary filtration and gross solids removal from water down to 35micron.
Water enters the holding tank and into the center of the drum. Fine screenings are filtered from the water as it passes from the inside of the filter to the outside. From here the water flows over a weir within the holding tank to the discharge pipe.
Cleaning of the screen is performed automatically via a wash water system. The washing cycle is controlled by a timer, which is typically 10% of the operating time. External wash jets clean the filter and push debris into the central collector, where it is removed for disposal via the discharge pipe. The clean surface of the screen then travels back down into the feed channel. The wash cycle continues until the downstream water level returns to normal.
The Flootech Rotary Drum Filters have several advantages over traditional drum screens. One significant advantage is the very high surface area for the required installed tank volume (m2/m3), which is only possible due to the unique design of the drum. This provides the Flootech Rotary Drum Basket Filters with significant capital and operating costs savings compared with current technologies.
Flootech Rotary Drum Filters can be combined with Dual Flow Basket Filters to provide complete intake solutions with very high filtration grades (35 – 50micron).
