The drum-type microfilter uses a high-precision stainless-steel screen to remove suspended solids, residual feed, and fine particles from circulating water. It features automatic water-level monitoring and pressure-triggered backwashing, ensuring continuous cleaning without manual shutdown. With corrosion-resistant 304/316 stainless steel or PE housing, the system maintains long-term durability in acid, alkali, and saltwater environments.
This microfilter is widely used in aquaculture tail-water treatment, cage culture water purification, and nursery pond impurity removal. It is also suitable for industrial circulating water systems in power, chemical, and textile factories, preventing pipeline blockage. In municipal and landscape projects, the filter supports residential sewage treatment and water-quality maintenance of artificial lakes and landscape ponds.
A rotary drum filter is a mechanical microfiltration filter designed to remove fine particles and suspended solids (TSS) from water. It is a core component of any recirculating aquaculture system (RAS) and is specifically designed to remove fish feces and waste, preventing them from breaking down into toxic ammonia and nitrites.
Core Value: Automatic backwashing for 24/7 continuous filtration.
Key Benefits: Reduces labor, stabilizes water quality, and protects your biofilter.
