Hamburg stands as Northern Europe’s preeminent logistics hub and a powerhouse of heavy industry, chemical manufacturing, and maritime trade. The metropolitan area, home to critical operations like the Port of Hamburg, the Harburg refinery zone, and multiple municipal wastewater complexes (such as the central Köhlbrandhöft facility), generates massive volumes of organic and inorganic sludge daily. For these operations, minimizing waste volume before incineration or transport is an economic imperative.
A key operational hurdle in Hamburg is managing local sludge streams under strict German wastewater disposal standards. The single screw press has emerged as a fundamental tool here. By utilizing mechanical squeeze forces, our screw press systems continuously dewater primary, secondary, and tertiary sludge mixtures. They achieve a high percentage of dry solid cake while drastically reducing energy consumption compared to traditional high-speed decanter centrifuges.
Moreover, local grain-based bio-refining, starch manufacturing, and brewery facilities along the Elbe River rely on single screw presses to process wet waste residues (spent grains, fiber fractions, starch pulp) into highly stable feed materials. This supports the regional bio-circular economy while safeguarding local waterways from nutrient runoffs.
A single screw press works by feeding raw, flocculated slurry into a cylindrical screen assembly containing a slowly rotating screw shaft. The screw flight pitch decreases, and the inner shaft diameter increases from the inlet to the outlet. This geometry compresses the material as it moves through the press. Water is squeezed out through the mesh screens, leaving dried solids (cake) to discharge through a backpressure regulator at the end.
For demanding applications like paper mill fiber separation, chemical processing, or municipal sludge treatment in Germany, standard off-the-shelf machinery is rarely sufficient. System configurations must account for specific variables such as screw shaft taper, compression ratios (ranging from 1:2.5 to 1:6), wedge-wire sizing (0.1mm to 1.5mm), and rotational speeds (typically 1 to 5 RPM) to prevent screen clogging while keeping throughput high.
Our single screw press line features segmented, modular screen baskets that permit rapid disassembly and screen changeovers, minimizing maintenance down-time. Screw shafts are overlay-welded with heavy-duty tungsten carbide at high-wear areas, extending system life when handling abrasive materials like sand-laden municipal sludge or diatomaceous earth residues.

Founded in 1992 and located in Zhoutie Town, Yixing City—near beautiful Taihu Lake—Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. spans over 54,000 square meters. Our manufacturing plant operates with modern production setups, utilizing heavy-duty plate rolling machines, automatic tube-to-tubesheet orbital welding, and dedicated CNC machining centers to build heavy process equipment.
Our long-term success is built on supply chain resilience. Operating out of Yixing's industrial manufacturing cluster, we have direct access to raw materials and heavy castings. This allows us to source high-grade SS304, SS316L, and duplex stainless steel at stable rates, insulated from wild global market swings. For our clients in Hamburg and wider Germany, this means reliable lead times, traceable material certifications, and consistent pricing.
The industrial landscape in Hamburg demands continuous efficiency improvements. Our engineering roadmap focuses on integrating advanced diagnostics and automated process controls directly into our single screw press lines. By adding digital torque sensors and feed-slurry density monitors, our systems can dynamically adjust the rotational speed of the screw and the backpressure cone displacement. This maintains stable cake moisture output even when feed thickness fluctuates.
Additionally, modern environmental laws in Europe place high importance on carbon neutrality. By combining our energy-efficient single screw press systems with our Mechanical Vapor Recompression (MVR) evaporation plants, we help plants recover heat energy. The liquid pressed out of organic sludge or starch by-products can be concentrated in our MVR evaporator using recycled waste steam, resulting in zero-liquid-discharge (ZLD) configurations that save significant amounts of energy.
