Product Overview
The Decanter for Wastewater Treatment is a horizontal decanter centrifuge for continuous sludge treatment in municipal and industrial wastewater projects. It is supplied to wastewater treatment plants, environmental engineering companies, system integrators, and equipment distributors.
The centrifuge separates suspended solids and sludge from the liquid phase, with continuous liquid clarification and concentrated solids discharge.
Wastewater Applications
Municipal Sewage Sludge
Primary sludge, waste activated sludge, and mixed sludge for sludge dewatering and thickening.
Chemical Wastewater Sludge
Chemical precipitates and fine solids for solid-liquid separation and sludge dewatering.
Food and Brewery Wastewater
Organic solids, fermentation residues, and sludge for solids separation and sludge dewatering.
Pharmaceutical Wastewater
Pharmaceutical residues, fine suspended solids, and treatment sludge for continuous solid-liquid separation.
Paper Mill Wastewater
Fiber-containing sludge and suspended solids for solids concentration and dewatering.
Mining Wastewater
Coal particles, sand, mineral solids, and abrasive sludge for continuous solid-liquid separation.
Oily Wastewater
Oily sludge containing oil, water, and suspended solids for liquid-solid or three-phase separation.
Equipment Configuration
Anti-Clogging Screw
Screw conveyor design for continuous discharge of high-concentration and oily sludge.
Dual-Frequency Drive
Common-bus dual-frequency drive with independent bowl speed and differential speed control.
Wear Protection
Tungsten carbide tiles and ceramic sleeves for applicable wear-prone components.
Wetted Materials
304, 316L, and Duplex stainless steel options for corrosive wastewater applications.
Control Interface
MODBUS communication and DCS monitoring are available for applicable control configurations.
Plant Integration
The centrifuge connects the sludge feed system with the plant's liquid discharge and solids handling systems.
The upstream interface covers feed pumping, polymer dosing, and mixing where required. The liquid outlet connects to return or further treatment, while the solids outlet connects to conveying, storage, disposal, or subsequent processing.
Project engineering confirms foundation dimensions, process connection positions, electrical interfaces, maintenance clearance, and lifting access.

FAQ
Can Yuanrong quote from an existing equipment specification?
Yes. An equipment schedule, process specification, technical drawing, or existing machine reference can be used for technical clarification and quotation.
Can Yuanrong supply the centrifuge as part of a treatment package?
The confirmed supply scope can include the centrifuge, auxiliary equipment, control interfaces, and other specified package components. Included and excluded items are listed in the quotation.
Can Yuanrong replace a centrifuge from another manufacturer?
Replacement projects are reviewed using the existing machine model, nameplate data, installation dimensions, process connections, electrical data, operating load, and current treatment results.
What information is required for a quotation?
The basic quotation data are sludge source, feed flow, feed solids concentration, dry-solids load, separation duty, sludge characteristics, installation conditions, and electrical requirements.
How are technical requirements confirmed before production?
Feed characteristics, process load, machine configuration, installation requirements, control interface, and supply scope are reviewed before order confirmation.
Can the same configuration be supplied for repeat projects?
Project and equipment records provide a reference for repeat orders, replacement units, and standardized engineering projects.
How is commissioning handled after installation?
Commissioning covers equipment operation, safety, maintenance, and basic fault diagnosis. Operator training is included within the confirmed service scope.
What is the warranty period?
The centrifuge carries a one-year warranty from the qualified commissioning date.
How are spare parts supplied?
Spare parts are matched to the supplied machine model and configuration. Wear parts and replacement components are supplied for maintenance and long-term operation.
How are product quality issues handled?
Product quality issues receive an initial response within 2 hours for technical review and follow-up.
Can Yuanrong support overseas projects?
Delivery, technical documentation, commissioning, operator training, and spare-parts support are arranged within the confirmed project scope.
