All intelligent box type microfilter is made of non-toxic and corrosion-resistant food grade PP material. It is mainly composed of box assembly, drum assembly, reverse cleaning system, electric control box system and transmission system. The water flow is less than or equal to 10m³/h. The equipment uses food grade environmental protection 316 stainless steel filter as the medium to remove suspended solids (≥50 μm).

The equipment adopts automatic liquid level control. When the suspended matter in the drum accumulates, it causes the decrease of water permeable through the filter, resulting in the rise of the water level outside the drum. The cleaning system then triggers the backwash pump and drive system. Rotating drum filter continuous high pressure cleaning washes sewage to the collecting groove for direct discharge.

Operating Modes:

• Manual: Control backwash pump and drum rotation via dedicated start/stop buttons.
• Automatic: Controlled by water level float ball. Triggers backwash for a set duration when the water level rises.

Important Considerations:

The machine is widely used in aquaculture for raw water filtration (sediment, algae, particles) or closed-cycle purification.

• Material: PP box body with 10+ years lifespan; corrosion and high-temperature resistant.
• Design: Detachable flushable design; inclined bottom for no-dead-corner cleaning.
• Function: Biochemical filtration for rapid bacterial culture and nitrification system establishment.
