Efficient, Compact, Stainless, Reliable

The QLD Dewatering Screw Press delivers continuous 24/7 automated sludge dewatering with a jam-resistant slow-running screw and PLC-controlled motor to cut labor, water and disposal costs while keeping operations enclosed to minimize odors. Built from SUS304 stainless steel with an integrated electrical cabinet, compact footprint and sealed design, it offers durable quality, easy maintenance and reduced cleaning water consumption. Shipped in standard export cartons with 3–20 day delivery and available in multiple models, the QLD Dewatering Screw Press pairs with sludge pumps and polymer dosing systems for turnkey, ready-to-install wastewater treatment.

PLC Controlled 500L/h Dewatering

The QLD Dewatering Screw Press is a compact stainless‑steel (SUS304), PLC‑controlled sludge dewatering system (220/380V) with a 500 L/h capacity and integrated electrical cabinet, disposal tank and dehydrator to minimize footprint while providing enclosed, low‑odor operation. Its slow‑speed motor drives a screw through stacked fixed and moving rings with polymer conditioning to deliver continuous 24‑hour automated dewatering for high or low consistency dye wastewater, offering anti‑jam self‑cleaning, adjustable cake moisture via screw speed and back‑pressure, and reduced water and energy use to lower operating and labor costs. The screw‑and‑ring structural design forces sludge through narrow gaps to form and extrude cakes, the moving ring cleans gaps to prevent blockage, and easy access points simplify maintenance while extending service life.

PLC Controlled 500L/h Dewatering

The QLD Dewatering Screw Press is a stainless steel, PLC-driven screw sludge dewatering system (220/380V) designed for dye wastewater and industrial sewage, delivering a 500 L/h treating capacity in an enclosed unit to reduce odor and noise. Its integrated electrical cabinet, dosing and dehydrator design enables continuous 24-hour automatic operation with anti-jam moving rings, low power consumption and reduced cleaning water use. Adjustable screw speed and back-pressure gaps allow control of throughput and cake dryness for printing & dyeing, food, chemical and municipal applications, while the compact layout simplifies installation and maintenance.

FAQ

What is the Dye WW Screw Sludge Dewatering PLC Motor 500L/h 220/380V used for and in which application scenarios is it best suited?

This unit is designed to dewater sludge from dyeing and textile wastewater streams, pigment and chemical sludges, and similar industrial effluents. Typical scenarios include small-to-medium textile mills, dye houses, pre-treatment lines for biological or membrane systems, pilot plants, and wastewater treatment plants that need mechanical thickening before disposal or further treatment. It is intended to recover water, reduce sludge volume and lower disposal costs.

The spec lists 500 L/h — what does that mean in practice and what affects actual throughput?

The 500 L/h rating refers to the typical slurry feed volume the screw press can handle under standard conditions. Actual capacity depends on feed solids concentration (TS%), sludge characteristics (organic/inorganic, fibrous, sticky), polymer/flocculation efficiency, and pre-thickening. As a practical guide, typical feed solids between about 0.5–6% TS are handled; well-conditioned sludge will allow higher throughput and dryer cake. Expect variability in cake dryness and flow — specify test data with your sludge for accurate sizing.

The product lists 220/380V — how should I connect it and what electrical considerations are important?

220/380V indicates compatibility with common supply voltages: 220V (often single-phase) or 380V/400V (three-phase) depending on the motor configuration and your locale. Always match the actual motor nameplate voltage and phase to your site supply, ensure appropriate fusing and overload protection, and provide proper grounding. If you need soft start, speed control or optimized torque for varying loads, add a variable frequency drive (VFD) or configure the PLC to interface with one. Have a qualified electrician perform wiring and commissioning.

What automation and control features does the PLC offer for operation and monitoring?

The PLC provides automated control of the screw press cycle: start/stop, run timers, feedpump coordination, polymer dosing interlocks, motor protection and fault alarms. Typical PLC functions include parameter settings (speed, cycle time), alarms (overload, jam, low/high level), data logging of cycle counts or run hours, and optional remote monitoring or SCADA integration via standard comms (Modbus, etc.) if fitted. This reduces manual intervention and improves repeatability.

How do I integrate this unit into an existing wastewater treatment line?

Place the screw press downstream of a primary settling or thickening stage and after any required chemical conditioning (coagulant/flocculant). Typical skid layout includes a feed hopper or buffer tank, feed pump (or gravity feed if available), a polymer dosing system, the screw press, and a cake discharge point and filtrate return. Provide adequate space for service access, a level foundation and anchoring, and pipework for filtrate drainage. Run factory acceptance tests or site trials to tune polymer dose and feed rate for best performance.

What routine maintenance and common troubleshooting steps should I expect?

Routine tasks: daily inspection for leaks and unusual noises, clean screens and feed ports, check polymer feed and mixing, weekly lubrication per manual, monitor motor amp draw and PLC alarms, and inspect/replace wear parts (screw flights, screen elements, bearings) on a scheduled basis. Common issues: low cake dryness (usually fixed by optimizing polymer/flocculation, reducing feed solids, or slowing feed), reduced throughput (clogged screens or worn screw), motor overloads (blockage or incorrect operation), and polymer pump faults. Keep spare wear parts and a recommended polymer on hand, and follow the manufacturer’s maintenance schedule.
