Product Overview
The Waste Water Decanter Centrifuge is a horizontal decanter centrifuge for municipal and industrial wastewater treatment. It is supplied to wastewater treatment plants, environmental engineering companies, system integrators, and equipment distributors handling sludge and solid-containing wastewater.
What Wastewater Can It Treat?
Municipal Wastewater
Handles primary sludge, waste activated sludge, and mixed sludge from municipal treatment plants, removing water to produce drier cake and reduce sludge volume for transport and disposal.
Industrial Wastewater
Dewaters sludge from chemical, food, brewing, pharmaceutical, paper, and steel wastewater treatment, reducing water content for easier sludge handling and disposal.
Printing and Dyeing Wastewater
Separates water from concentrated treatment sludge and fine suspended solids, producing concentrated solids for downstream handling.
Pharmaceutical Wastewater
Separates treatment sludge, pharmaceutical residues, and suspended solids from wastewater, reducing the solids load for subsequent treatment or disposal.
Food and Brewery Wastewater
Handles organic suspended solids, fermentation residues, and process sludge from food, beverage, dairy, and brewing plants, reducing water content and sludge volume.
Mining Wastewater
Separates coal, copper, non-ferrous mineral, sand, and other mineral solids from wastewater, concentrating solids for subsequent handling.
Process Integration
The centrifuge is installed between the upstream feed system and downstream liquid and sludge handling equipment. Feed enters continuously, while separated liquid and solids leave through separate outlets.
Feed Side: Feed pumps, polymer dosing, and mixing equipment connect to the centrifuge feed line where required.
Liquid Side: Separated liquid leaves through the liquid outlet for return to the treatment process or further treatment.
Solids Side: Concentrated solids leave through the solids outlet for conveying, storage, disposal, drying, or further treatment.
Engineering Interfaces: Foundation dimensions, feed and discharge connections, electrical interfaces, maintenance clearance, and lifting access are confirmed before installation.
Equipment Configuration
Dual-Frequency Drive
The common-bus dual-frequency drive provides independent control of bowl speed and screw differential speed.
Wear Protection
Tungsten carbide tiles or ceramic sleeves are available for components exposed to abrasive sludge, sand, and mineral solids.
Wetted Materials
304, 316L, and Duplex stainless steel options are available for wastewater streams containing corrosive components.
Three-Phase Configuration
The LWS series supports separation of a light liquid phase, heavy liquid phase, and solid phase for applicable wastewater streams.
FAQ
1. Can the centrifuge replace another manufacturer's machine?
Yes. Existing equipment model, foundation dimensions, connections, processing data, and operating conditions are reviewed before the replacement configuration is confirmed.
2. What information is required for a replacement quotation?
The existing equipment model, nameplate information, installation dimensions, process capacity, feed characteristics, and current operating results provide the basis for replacement evaluation.
3. What happens if project data changes after order confirmation?
Changes to flow, solids concentration, feed composition, or treatment duty are reviewed against the approved technical specification before production changes are made.
4. What documents are supplied for project approval?
The applicable package includes technical specifications, installation information, operating instructions, inspection records, and product certificates.
5. How are technical changes handled after the purchase order?
Changes affecting the model, materials, drive system, accessories, or supply scope are confirmed in revised technical documentation before production.
6. What does the buyer need to prepare before installation?
The project site prepares the foundation, utilities, lifting conditions, installation area, and required electrical connections according to the supplied installation information.
7. How are spare parts identified for future purchases?
Spare parts are matched to the original centrifuge model and supply records to maintain configuration consistency for future orders.
8. What support is provided after installation?
Yuanrong provides commissioning and operator training covering operation, safety, maintenance, and basic fault diagnosis.
9. What is the warranty period?
The centrifuge carries a one-year warranty from the qualified commissioning date. Product quality problems receive an initial response within two hours.
10. Can repeat orders use the same equipment configuration?
Yes. Previous model, technical specification, and supply records are retained for repeat quotations and order confirmation.
