Esmil is proud to showcase the advanced functionality of its Multi-Disk Screw Press MDQ through a detailed 3D animation. This cutting-edge equipment is revolutionizing sludge dewatering with its robust design, user-friendly operation, and exceptional performance across various sludge types, including those with high-fat and high-oil content.

Reliability and trouble-free operation

The Multi-Disk Screw Press MDQ is engineered for durability and reliability, capable of handling diverse sludge types without issues. Operating at a low speed of 0.5-2 rpm, the press’s slow-rotating screws ensure smooth operation while minimizing wear and tear. The dewatering drums feature a self-cleaning design with specialized disks that keep the filtration surface clear, eliminating the need for frequent maintenance and costly cleaning procedures.

User-friendly operation

Ease of use is a hallmark of the MDQ design. After just one day of training, operators can efficiently manage the machine, making adjustments, and performing maintenance, including complete disassembly and reassembly if needed. This makes the MDQ ideal for smaller wastewater treatment plants that may not have a full staff of highly skilled technicians.

Optimal for high-fat and high-oil content sludge

The MDQ is particularly effective in dewatering sludge with high concentrations of fats and oils, such as those generated in dissolved air flotation (DAF) processes and by the food industry. Its superior handling of greasy, abrasive sludge makes it a preferred choice for meat processing plants, where other dewatering methods, like centrifugation, often fall short.

Superior flocculation and clean filtrate

Esmil's Multi-Disk Screw Press integrates a flocculation chamber designed to create optimal conditions for forming and maturing flocculas. The system allows for visual monitoring and control by the operator, ensuring high-quality flocculation. The flocculated sludge is then gently transferred to the dewatering drums without pumping, which prevents disruption of the flocculas. This process results in an exceptionally clean filtrate, as the majority of the filtrate is separated from the sludge in the thickening zone through gravity, avoiding the contamination typically seen when particles are pressed through filter gaps.

Energy efficiency and minimal water usage

The MDQ screw press is also a leader in energy efficiency, consuming as little as 0.0004 kWh per gallon of initial sludge. This low energy consumption translates into significant cost savings and a reduced environmental footprint. Additionally, water usage is minimized due to the press’s innovative design, which employs the movement of the disks to keep the filter gaps clean, requiring only standard pressure flushing.

Convenient maintenance and compact design

With high-quality components and a horizontal drum configuration, the MDQ is easy to maintain, ensuring long-term reliability. Key parts are accessible with standard tools, and the equipment operates with minimal noise, further enhancing ease of maintenance. The compact footprint of the multi-disk screw press makes it an ideal choice for facilities with limited space.

Enhanced durability and longevity

Esmil’s commitment to quality is evident in the enhanced strength of the drum and the durability of the screws. The fixed disks are supported by a robust drum frame, and the screw blades are reinforced with FREA-METAL, a highly wear-resistant material that extends the operational life of the screw shaft to around 50,000 hours. The MDQ disks are precision-engineered from a single piece of metal, ensuring minimal deviation and an exceptionally long lifespan.

Esmil’s Multi-Disk Screw Press MDQ represents a leap forward in sludge dewatering technology, combining reliability, efficiency and ease of use with advanced design features that minimize operational costs and environmental impact.
