Engineered by Jiangsu Zongheng to meet the heavy industrial demand of Jakarta, offering high output efficiency, minimal energy footprint, and maximum wear-life reliability.
The Greater Jakarta Area (Jabodetabek) is the heartbeat of Indonesia's manufacturing power. Key sectors including municipal waste management, food processing, bio-energy, pharmaceutical extraction, and chemical refinement generate vast streams of wet waste and high-moisture slurry daily. Disposing of raw, wet slurry is not only logistically expensive but is increasingly restricted under DKI Jakarta's strict municipal waste regulations.
The Single Screw Press has emerged as the definitive standard for industrial solid-liquid separation. Compared to traditional decanter centrifuges, screw presses consume up to 80% less electrical energy, operate at significantly lower RPMs (meaning minimal mechanical wear), and handle fluctuating inlet solid concentration without clogging.
"As regulatory policies in Tanjung Priok, Bekasi, and Tangerang converge toward zero-liquid discharge and resource recovery, integrating high-performance mechanical dewatering is no longer optional—it is a core economic driver."
Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd is the premier global manufacturing partner delivering customized Single Screw Press systems configured for tropical conditions and heavy industrial operations characteristic of Jabodetabek.
Discover the physical engineering behind the dewatering systems that optimize moisture extraction across Indonesian agriculture, chemical processing, and wastewater lines.
The mechanical principle of a single screw press relies on progressive volumetric compression. As the material enters the cylindrical housing, the helical screw rotates at a slow speed (usually between 5 to 20 RPM). The pitch of the screw blades decreases from the inlet to the discharge end, which continuously reduces the volumetric space and builds intense pressure against the material.
Liquids are forced out through the screen baskets (perforated or wedge-wire configurations), while the compacted dry solids are pushed past an adjustable air-actuated cone (pneumatic back-pressure regulator) at the outlet, ensuring constant moisture reduction even under variable flow conditions.
Our presses are designed utilizing finite element analysis (FEA) to withstand immense torsional stress. By utilizing duplex stainless steels (SUS304, SUS316L, or SAF2205) and hardfacing the screw flight tips with stellite alloy, Zongheng ensures a design life exceeding 20 years in highly abrasive applications such as palm oil mill effluent (POME) treatment and tapioca pulp dewatering.
Indonesia is one of the world's leading producers of cassava starch. Our single screw press extracts juice from residual tapioca fiber (bagasse) to reduce moisture content from 85% down to under 55% prior to thermal drying, resulting in huge energy savings for starch factories in Lampung and West Java supplying the Jakarta market.
For fermentation and alcohol distilleries in the Jakarta periphery, dewatering spent grains (DDGS) is critical. Zongheng screw presses act as the crucial pre-drying stage, stripping free moisture to yield a manageable cake that can be directly fed into our high-performance Tube Bundle Dryers.
Handling municipal wastewater in DKI Jakarta or biological chemical sludge from industrial parks (Tangerang, Karawang) requires robust equipment. Our screw presses effectively handle flocculated biological sludge with minimal polymer consumption and high filtration efficiency.

Providing the secondary concentration phase for liquid effluents before drying, maximizing overall plant thermal efficiency.
A falling film evaporator efficiently concentrates heat-sensitive liquids. The feed liquid forms a thin film flowing down heated vertical tubes, where it partially evaporates. Vapor generated flows parallel to the liquid, enhancing the process. It ensures a short residence time and low operating temperature, preserving product quality.
The system requires proper liquid distribution and complete surface wetting to prevent fouling and maintain high thermal efficiency and operational stability. It is widely applied across Jakarta's biological extraction, pharmaceutical manufacturing, and wastewater recycling projects.

Performance depends on the material's physical structure, fiber length, and initial viscosity. For organic fibers, tapioca bagasse, corn hulls, and DDGS, moisture content is typically reduced from 80-85% down to 40-50% in a single continuous pass. This dry cake can then be handled, stored, or processed in thermal dryers.
Decanter centrifuges rely on high-speed rotation (3,000+ RPM) which consumes significant electrical energy and requires frequent bearing maintenance. A Single Screw Press operates at low speeds (5-20 RPM), consuming up to 80% less power with reduced wear, making it a reliable option for biological and plant fiber sludge.
Yes. We customize the materials of construction based on chemical compatibility. For acidic, alkaline, or abrasive slurries, we utilize SUS316L, duplex stainless steels, or wear-resistant stellite alloys welded on the screw flight tips. The screen baskets are also reinforced to prevent abrasion-driven pore expansion.
Standard model fabrication requires 45 to 60 days in our Yixing factory, followed by direct shipping from Shanghai to Tanjung Priok, Jakarta (approx. 12-15 days ocean transit). Zongheng offers complete commissioning support, sending qualified engineers for piping layout verification, trial runs, PLC program integration, and local operator training.
