LW(Environmental Decanter) series decanter centrifuge is designed for environmental industry for sludge dewatering, waste water treatment, waste oil recovery and treatment. It is also called solid bowl centrifuge, or decanter. The decanter centrifuge have been proved to be the most cost-effective solution for sludge treatment, waste water treatment and waste oil recovery include solids liquid separation, sludge dewatering and sludge thickening.The main target of separation from the liquid and solid phase is to get solid phase with the least possible residual moisture. And at the same time the decanter need to minimize possible solid particle residues in the separated liquid phase.
Shenzhou Environmental Decanter Centrifuge Features & Benefits
SHENZHOU series centrifuge is specially designed for sludge treatment.
SHENZHOU series centrifuge bowl material is Duplex Stainless Steel 2304 made from centrifugal casting.
The screw conveyor inside the bowl is protected by Tungsten Carbide Tiles for longer operation.
SHENZHOU decanter reduce total disposal volume by as much as 70%
SHENZHOU decanter discharge stackable cake free of liquid
PLC and VFD controlled automatically operation to meet different applications.
Less people required, and low maintenance with continuous operation
Minimize footprint and easy installation.
The bearing is SKF premium bearing for reliable operation.
Compared to other separation equipment, the advantages of the decanter centrifuge are its wide range of potential use coupled with its continuous operation and ability to accept a wide range of feed material. The decanter centrifuge can be used for most types of liquid/solid separation. The function of the sludge treatment decanter centrifuge include dewatering sludge to dry cake, classification of solids in liquid suspension, or clarification of liquids and recovery of required solids.
SHENZHOU Sludge Treatment Decanter Centrifuge Application
Municipal or Industrial Sludge Dewatering
Industrial waste water treatment
Digested Sludge dewatering
Thickening of activated sludge
Animal Waste Treatment
Dissolved air flotation sludge treatment
SHENZHOU WASTEWATER DECANTER CENTRIFUGE
LW series are high performance decanter centrifuge designed for waste water treatment for different types of municipal and industrial wastewater.LW decanter centrifuges are widely used in municipal and industrial wastewater treatment plants for the purpose of producing a clean, safe water discharge within the required limits. As the environmental considerations and the consent limits are becoming more and more strict .The New waste water treatment plants built today are becoming more and more sophisticated, but to improve the efficiency of waste water treatment, the LW decanter centrifuges are extensively used for liquid-solid separation, sludge dewatering, and sludge thickening applications.

WASTE OIL DECANTER CENTRIFUGE
LW waste oil treatment or oil recovery decanter centrifuges specially equipped to meet the separation requirements of the waste oil processing industry with specialized separation equipment and systems technology. The LW decanter centrifuge series were designed and developed for high capacity waste oil treatment. Because of the special design, LW decanter centrifuge is capable to maximize the oil recovery, solids capture and cake dryness.
SHENZHOU not only provides the individual waste oil treatment decanter centrifuge, but also we can provide complete waste oil treatment or recovery package system. This typically include transfer pumps, premixing unit, primary screening machine (shale shaker), 2 phase decanter centrifuge, 3 phase disc centrifuge, chemical dosing system etc. This complete package is a turnkey solutions for clients for the waste oil treatment or oil recovery.
The main application of the waste oil decanter centrifuge include following:
Waste oil from storage tank bottom
Waste Oil sludge lagoons
Oil refineries slope oil or waste sludge
Oil water and solids mixtures from ship ballasts
Separation equipment discharged waste oil
Drilling waste oil from oilfield
Discarded lubricant oils and emulsions or other
Industrial waste oil and water and emulsion
The waste oil treatment system design vary depending on the make-up and source of the waste stream and also it vary because of the goal is different. But typically, the waste oil treatment system will include following:
Mechanical removal of solids by different separation machine.
Pre-mixing and Heating system to reduce viscosity and thus enhance mobility of waste material.
Chemical dosing to break emulsions and make oil, water and solids bound in the emulsion accessible for easier separation by G force.
In order to enhance solids removal rates and the discharged cake dryness, normally polymer will be used.
