Drum Filters

Drum Filters in Land Based Fish Farms

Drum Filters for aquaculture farms are mechanical units which materialize an efficient, robust and reliable solution in the process of solid and organic matter separation and filtration. These automatic self cleaning microscreen filters are able to handle a wide range of flow rate, 1m³/h – 4000m³/h and backwash, utilizing micron rates from 10μm up to 10000μm. They are designed for high performance filtration in land based aquaculture water treatment systems such as salmon farms.

A well-considered and corrosion resistant mechanism require no lubrication and on only simple maintenance that can be done by all type of staff. Robust structure of the drum filters allows the longest warrant duration of the market. Filter panels are modular and protected by patent pending support structure. The filters are energy efficient with internment and continuous backwash modes for sake of lowest water consumption levels. Smart Wash Logic Control enables operational mode selection, rotational speed adjustment, autonomous selection for optimum washing speed/time.

Engineering & Operation

Types of Drum Filters

The Micro Drum Filters are available with different configurations.

• Available in 7 different drum diameters: 0.5 m -2.2 m OR 1.64 ft to 7.21 ft.
• Available Filtration Area: 0.7 m²–21 m² or 7.53 ft² to 226 ft².
• Available in two material types: All pastic tanks by Polypropylene (PP) or Titanium / Stainless Steel / Super Duplex Frame.

Application in Salmon Farming RAS & Land Based Aquaculture

The MAT-KULING Drum Filters are specifically designed for land based aquaculture fish farms, salmon farms, hatcheries and other fish farming applications. They are available in stainless steel 304,316, Duplex SS, Super Duplex SS and Polypropylene in order to be able to treat both salt and fresh water fish farms.

Drum Filters Operation & Backwash Process in 6 Steps

1. Untreated water enters the drum and is filtered through the screens before passing back to the system.
2. Driving Force (Sieving) = The difference in water level inside/outside the drum.
3. Solids are trapped and lifted to the backwash area by the rotational movement of the drum.
4. Drum rotation can be intermittent or continuous depending on the type of control set by the operator.
5. Backwash water is sprayed via nozzles from the outside onto and through the filter screens.
6. Rejected materials are washed out of the filter screen into the collection tray and discarded from the filter using gravity.
