Automatic Rotary Drum Filter Microfilter for Circulating Aquaculture System

ROTARY DRUM FILTER
Rotary drum filter for aquaculture farms is mechanical and self-cleaning micro-filtration equipment, which is designed for high performance in water-treatment systems. It uses a rotating drum to separate the micro suspended solid out of the water to reach solid-liquid separation. Dirty water enters the inside of the drum through a water inlet and the drum is covered with a stainless steel (316L) micro screen. From here it passes through the filter screen to the filter chamber, leaving all impurities on the inside of the filter screen. Waste particles slowly block the filter screen causing less water to pass through the drum leading to a higher water level inside the filtering drum. Once the water inside the filtering drum rises to the specified level, the automatic control system starts to work, the back wash pump and drum motor will be open automatically at the same time. During the washing process, the water under pressure rinses the dirt from the inside of the filter screen to a waste tray, and then leaves the filter through a sewage outlet. After one rotation of the drum, the filter
