Affordable, Efficient, Durable, Guaranteed

The QTBH sludge dewatering machine delivers reliable, low-cost desalination with a motor and PLC for efficient, low-energy, low-noise screw-press operation. Built from SUS304 stainless steel with Swiss filter cloth, compact modular belt widths and standard export carton packaging, it produces low-moisture cake and needs minimal maintenance. Backed by a one-year warranty and fast delivery, it integrates easily with pumps and dosing systems for industrial, municipal and food‑industry dewatering needs.

Economical Motorized Screw Desalination

The QTBH sludge dewatering machine is a low-cost screw press with motor and PLC control and a 1-year warranty, constructed from SUS304 stainless steel and fitted with imported Swiss filter cloth and an air-chamber automatic deviation device for durable, quiet (≤75 dB) and energy-efficient desalination and dewatering. Designed to handle a range of inlet consistencies and capacities across multiple belt widths (QTBH-1000 to QTBH-2000), it delivers high throughput, low cake moisture, flexible operation and minimal maintenance, creating clear value through reduced operating costs and reliable separation performance. Its compact screw-press structure, integrated safety monitoring with automatic stop and easy integration with pumps, dosing systems and washing units make it simple to install, automate and operate in industrial, municipal or food and beverage applications.

FAQ

What is the Low-Cost Screw Press (Motor & PLC) used for in desalination plants?

It’s used to mechanically dewater sludge and solids generated by desalination pretreatment (e.g., sand filters, multimedia filters, coagulation/flocculation) and RO membrane cleaning waste. The screw press reduces sludge volume and increases solids content to lower disposal and transport costs, while the PLC and motor provide automated, stable operation.

What types of feed materials and solid concentrations can this screw press handle?

It works best with biological sludge, chemical flocculated sludge, filter backwash solids, and similar slurries. Feed total solids typically range from 0.5% to ~8% (higher incoming solids improve performance). Final cake dryness will vary with feed characteristics and polymer dosing but commonly reaches roughly 18–30% total solids.

How does the PLC and motor improve operation and control for desalination applications?

The PLC automates start/stop sequences, alarm handling, dosing interlocks, and basic process logic (e.g., feed, screw speed, and backpressure control). The motor delivers consistent torque and speed required for continuous dewatering. Together they enable remote monitoring, fault diagnostics, and repeatable performance, reducing operator intervention and downtime.

What installation, pre-treatment and site requirements should I plan for?

Provide a stable, level foundation and proper anchoring for the unit. Pre-treatment is recommended: coarse screening, grit removal and chemical coagulation/flocculation or polymer dosing to condition solids for better dewatering. Provide appropriate feed pumps, piping, and drainage for filtrate/brine and cake disposal. Consider space for access, maintenance and a weather-protected location or corrosion protection if outdoors.

What does the 1-year warranty cover and what is excluded?

The 1-year warranty typically covers defects in the motor and PLC components and workmanship under normal use. Consumable and wear items—such as screens, seals, bearings, polymer dosing pumps, and screw elements subject to abrasive wear—are generally excluded. Warranty is voided by improper installation, misuse, corrosive damage without proper material selection, or unauthorized repairs.

What routine maintenance and troubleshooting should I expect on site?

Routine tasks: inspect and clean the screw, screen and feed areas; check and lubricate bearings and seals per manufacturer intervals; confirm motor and gearbox mounting and alignment; verify PLC alarm logs and communication; replace wear parts as needed. Common issues: reduced cake dryness (check polymer dosing or screen damage), motor overload trips (inspect blockages or excessive feed solids), and alarms from the PLC (review fault codes and reset after resolving root cause). Keep a small stock of critical wear parts and follow the supplier’s startup/training guidance.
