The drum screen "Mili Screen" is a self-cleaning/internal supply rotary screen. The fluid is supplied to the weir tank inside the screen by a pump or by gravity flow, and the supplied fluid overflows from the weir and flows into the inner surface of the screen. The screen drum itself rotates slowly in the opposite direction of the fluid flow, and through this reverse shear effect, it effectively separates solids from liquids. It is constructed of 304 or 316 stainless steel, and a cover can also be installed to block aerosols, noise, and odors. 【Product Lineup】 ■ Mili Screen-B Series ■ Mili Screen-CI Series ■ Mini Mili Screen ■ Mili Screen P2–(Punching Plate) 【Examples of Applications】 ■ Meat processing plants ■ Food ■ Chemicals (resins) ■ Livestock ■ Paper and pulp ■ Seafood processing ■ Sludge and waste ■ Wastewater treatment *For more details, please refer to the PDF document or feel free to contact us.

The "Center Flow Band Screen" is a treatment device suitable for coarse and fine screening of freshwater, seawater, urban wastewater, and industrial wastewater. It boasts class-leading filtration efficiency and employs a unique honeycomb screen element, an integrated water channel design, and a stainless steel casing, making it capable of handling harsh operating conditions. The incoming flow is directed to the screen within the water channel, where the flow direction is changed by 90° to pass through the screen panel, capturing solids on the screen while allowing wastewater to pass through. Typically, operation is controlled by the upstream water level or differential pressure level, and when the set water level or differential pressure is reached, the band screen is brought to a stop. The captured solids build up a mat that improves capture rates. For openings smaller than 5mm, a capture rate exceeding 87% has been demonstrated, making it ideal for treatment before delicate MBR systems. Additionally, the honeycomb screen exhibits the industry's best water treatment performance with over 90% open area, achieving processing capabilities 20-40% higher than standard perforated panels.
