The "Inclined Screen" is a simple solid-liquid separation device that utilizes the globally trusted and proven Johnson Screens. It features a special weir and baffle design that achieves uniform distribution and high capture efficiency. The design of the box weir evenly distributes the inflow water to maximize process efficiency, allowing for efficient dewatering even of fine materials. 【Features】 ■ Made of stainless steel (304/316) ■ In the HS-24, HS-48, HS-72, and HS-120 models, the screen panels rotate for easy maintenance and cleaning ■ Long-lasting screens ■ Slot width range: 0.15 to 10 mm *For more details, please refer to the PDF materials or feel free to contact us.

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 wastewater/drainage device "Spiral Sieve NSI-T/NSI-T/D" is an integrated unit for screening, conveying, washing, and compressing that uses a shaftless spiral conveyor. The compact and robust spiral sieve is integrated into a stainless steel receiving tank, regardless of the presence of a dewatering zone. Fluid flows into a screen basket that is open on the inlet side, capturing solids larger than the diameter of the punching holes or the width of the slots. The brushes are divided into individually replaceable segments, allowing for quick and cost-effective maintenance. 【Features】 ■ Screening and dewatering handled by one unit ■ Easy to retrofit ■ Hygienic stainless steel ■ Flanged inlet and drainage connection ■ High operational reliability with no clogging or fiber entanglement, and no pressure applied to the screen surface ■ No water required in the pressurization zone *For more details, please refer to the PDF document or feel free to contact us.

The "Multi-Rake Bar Screen KUR" is a product designed to reliably remove large amounts of debris through mechanical screening of wastewater in pump stations or at the entrance areas of public and industrial wastewater treatment plants. Developed based on years of expertise in sewage treatment plants, it successfully produces high-quality products characterized by economic efficiency and excellent cleaning performance through an innovative production process. Additionally, this product can be suitably adjusted for various applications. 【Features】 ■ Functions that reduce maintenance frequency, wear, and damage - Individual replacement of sprockets in the drive unit - Maintenance-free stainless steel roller chain - No bearings below the water surface ■ Reverse operation for observing blockages and removing obstacles within the bar rack ■ Short cleaning cycles with multiple rotating rakes *For more details, please refer to the PDF document or feel free to contact us.

The "Rotary Drum Screen RSI" is a product that performs precise filtration of wastewater/drainage in waterways, tanks, and basins using wedge wire, punching, and wire mesh screens. The solids accumulated on the screen after filtration are automatically transported, dewatered, compressed, and discharged. In contrast to the common technology that drives the screen via a discharge spiral conveyor, the driving energy acts directly on the drum. It can be customized to the minimum overall height according to installation space requirements, making maintenance of the drive unit easier. 【Features】 ■ No need for a center/drive shaft in the spiral conveyor ■ Capable of transporting relatively large particle sizes ■ The spiral opens in both the transport direction and axial direction during discharge, preventing clogging ■ Easy access to the compression zone ■ Compression zone equipped with a pressure flap 【Examples of Applications】 ■ Food ■ Meat ■ Paper and pulp ■ Aquaculture ■ Livestock ■ Chemicals ■ Wastewater treatment, sludge ■ Waste ■ Pretreatment for MBR (Membrane Bioreactor) *For more details, please refer to the PDF document or feel free to contact us.

The "Roth Pass Rotary Drum Screen" is a drum screen with scraping functionality designed for high-load processes. It is a continuously operating screen equipped with an automatic cleaning function, capable of solid-liquid separation of solids containing floating oil and highly adhesive solids. The drum screen is driven by a gear motor mounted on the side, and it has a built-in cleaning system on the inside. As an option, a spiral compactor SCD can be equipped for dewatering the collected solids! 【Features】 ■ Made of stainless steel (304 or 316) ■ Integrated cleaning spray bar ■ Sealed casing structure ■ Bronze scraper (optional) ■ Emergency overflow system ■ Stainless steel bearings *For more details, please refer to the PDF document or feel free to contact us.

The "Spiral Compactor SCD" is a product equipped with a shaftless spiral conveyor that compresses, dewaters, and transports sand, sludge, and other solids. It is less likely to clog with materials such as fibers and sand, and its size, length, and installation angle can be suitably adjusted to meet site requirements. Solids are supplied to a U-shaped conveyor trough via a hopper, where they are taken up by the shaftless spiral conveyor and further transported. 【Features】 ■ Economical and compact ■ Simple and quick maintenance due to a single transport structure ■ Durable spiral insert design ■ Sealed structure ■ No internal bearings to prevent clogging ■ Less likely to clog even with fibrous materials *For more details, please refer to the PDF materials or feel free to contact us.

The "Screening Wash Press NSP/NWP" is an integrated compression dewatering device capable of dewatering, compressing, squeezing, transporting, and cleaning solid materials. It provides a simple and reliable solution that can be flexibly and multifunctionally introduced into existing plants. With numerous units in operation, we have gained extensive knowledge and experience regarding applications in municipalities and industrial facilities. The grooved bottom significantly improves wastewater/drainage efficiency compared to conventional perforated plates. 【Features】 ■ High performance with low operating costs ■ Pressure can be variably adjusted ■ Reduction in replacement part costs due to a modular structure that allows for individual replacement ■ Resistant to clogging even with fibrous materials ■ Low wear due to low rotational speed *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.
