Esmil - Model MDQ -Multi-Disc Screw Press

The Esmil Tsurumi MDQ Multi-Disc Screw Press offers the most effective dewatering solution for municipal wastewater treatment plants and various industrial sewage sludges, including those with high fat and oil content.

MDQ presses are ideal for facilities that aim to minimize maintenance staff requirements and reduce operational costs.

The dewatering process of the MDQ Multi-Disc Screw Press operates with minimal energy consumption and requires very few additional resources, such as flocculant, rinsing water, and wear parts. It also demands less maintenance and supervision compared to other dewatering equipment.

After treatment in the multi-disc screw press, the dewatered sludge can achieve a residual moisture content ranging from 60% to 82%, with an average flocculant dosage of 1.5 to 3.5 kg/t of dry sludge matter.

• Activated sludge
• Primary sludge
• Aerobically digested sludge
• DAF sludge
• Biogas plant sludge
• Water treatment sludge
• Agriculture sludge

• The unique screw design and efficient operation of the presses ensure high energy efficiency, minimal reagent usage, and reduced rinsing water consumption. The wide range of power and performance options available guarantees the optimal equipment for each project.
• The multi-disc screw press effectively dewaters highly concentrated oil and fat sludge, making it ideal for fat-rich flotation sludge. This equipment is particularly well-suited for the food industry, including meat processing plants, where centrifugation systems and belt presses are not feasible.
• The use of low-powered screw drives (up to 2.2 kW) with adjustable speeds via frequency converters ensures minimal energy consumption. Additionally, regulating the mixing speed of flocculant and sludge, along with visual monitoring, allows for precise control and optimization of flocculant usage.
• The self-cleaning mechanism of the dewatering drum features two specialized discs that ensure automatic cleaning of the filtration surface. As a result, the equipment can operate continuously without interruptions or costly filter pore cleaning processes.
• The use of high-quality components and proven technical solutions guarantees a long service life and minimizes maintenance needs. The horizontal drum design simplifies the maintenance and replacement of wear parts, with all key components easily accessible for servicing with standard tools. Additionally, the dehydrators operate with minimal noise, enhancing convenience for maintenance staff.
• The MDQ Multi-Disc Screw Presses are compact and do not require extensive space or high costs for climate control. They can be easily installed in container-based wastewater treatment plants and mobile units.
• The presses are fully constructed from stainless steel AISI 304 or AISI 316, with an optional explosion-proof version of electrical components available.
