슬러지 탈수기 공급업체

Qingben Environmental Technology (Jiangsu) Co., Ltd. is a China-based Sludge Dewatering Machine Supplier manufacturing screw press, belt press, preconcentration and deep dewatering machines for municipal and industrial sludge. We engineer the complete line, including flocculation dosing, conveying and drying, so plant owners, EPC contractors and municipal operators deal with one accountable manufacturer from process design to commissioning.

Our available range and selection logic are organized around the real feed condition: flow, solids concentration, sludge origin and the cake quality needed by the downstream disposal route. Whether the specification is written for a Sludge Dewatering Machine or a sewage mud dehydrator, we use the same engineering data to size the machine, choose the drive and define the auxiliary equipment.

Sludge Dewatering Machine Supplier Range

We build eight machine families under our sludge dewatering equipment program. Each is available as a standalone unit or as a configured skid with polymer dosing, feed pump, control panel and interconnecting pipework.

Selection and Capacity Planning

We do not size sludge dewatering equipment by footprint alone. The hydraulic flow and dry solids load set the machine frame; the sludge source and conditioning set the achievable cake. A screw press operating at 2–4 rpm typically consumes about 1/8 of the energy of a belt press and 1/20 of a centrifuge, with unit power of 0.01–0.1 kWh/kg DS. It suits smaller installations, high-odor plants and projects where low maintenance and automatic operation matter.

Belt presses and high dry belt machines fit larger hydraulic flows, especially where sludge is not pre-thickened. For post-dewatering, sludge deep dewatering equipment lowers 80% moisture sludge to 60% or below, while the high-pressure belt continuous machine provides higher throughput in a maintenance-friendly horizontal layout.

Representative screw press selections are shown below as a starting point. Final model choice depends on feed variability, polymer performance and operating schedule.

Automation, Installation and Line Integration

Our standard screw press package integrates an automatic control cabinet, flocculation and conditioning tank, thickening and dewatering body, and liquid collecting tank. Each drive is independently variable frequency controlled, so the unit can start and stop individually and respond to fluctuating feed. Belt-type machines can be controlled on-site or remotely, and deep dewatering systems are supplied with an intelligent monitoring package that reduces the need for continuous supervision.

Installation scope depends on site layout. We supply a machine with defined sludge feed, filtrate, wash water, polymer and discharge interfaces, or a fully skidded package that reduces foundation and piping work. When dewatering is followed by drying, we coordinate the interface with a Low Temperature Sludge Drying System Supplier so the cake enters the dryer at the right moisture and consistency.

Quality Assurance and Project Acceptance

Our Yangzhou factory manufactures the mechanical structure, shaft, rings, frames and control systems, and we maintain ISO9001, ISO14001, ISO45001 and CE documentation across the production system. The same engineering team that prepares the layout also supports installation, commissioning and trial operation so the equipment can be handed over as a working part of the treatment train.

Project support includes technical consultation and planning, system integration, operator training, environmental impact assessment, project management and monitoring. This allows the dewatering line to be accepted not only as a delivered machine, but as a documented process with defined operating parameters and trained personnel.

Information We Use to Configure Your Solution

Maintenance, Spare Parts and Serviceability

Screw press dewatering bodies are self-cleaning because the relative movement between fixed and moving rings avoids the blockages common in mesh-type machines. Planned washing is short and scheduled in minutes per hour rather than as a separate shutdown. Wearing components are mainly the screw shaft and moving rings; actual replacement depends on sludge type, operating hours and adjustment quality.

For belt machines, maintenance access is simplified by the integrated frame design and, on the high-pressure belt machine, a horizontally arranged pressing area. Our technical support covers scheduled maintenance, troubleshooting, spare part supply and the option to upgrade or modify an existing machine when process conditions change.
