ZK SEPARATION Decanters for Oil Sludge Treatment Process
ZK Oil Sludge Decanter Equipment can effectively separate the oil, water, and solid components of the oily sludge mixture. It provides the best solution for oil slick sludge treatment. After collecting the oily (waste) water by steam heating, add suitable demulsifiers, active agents, etc. The oily water in the emulsified state can be demulsified, and the oily (waste) water after demulsification uses high-efficiency three-phase centrifuge. The machine carries out a three-phase continuous separation of oil + water + slag. The centrifuge separated water and the unlayered oil-water mixture are directly sent to the sewage treatment system for treatment. The dehydrated slag phase can be recovered by combustion or thermal desorption process. Residual crude oil, the separated oil, can be collected and used as crude oil.

Oil Sludge Treatment Process
- Sludge treatment is a complete set of production process, using the principle of oxidative demulsification and centrifugal separation. Its main equipment is composed of dosing system, feeding system, separation system, conveying system, and control system.
- After the oily sludge is collected and heated by steam, a suitable number of additives like demulsifier and active agent are added in it, so that the oily water in the emulsified state is broken. After demulsification, a high-efficiency LWS series three-phase decanter is adopted to realize the continuous separation of oil, water, and slag in the oily sludge, and the water separated and the oil-water mixture not demulsified are directly sent to the sewage treatment system for treatment. Then, a LW series two-phase decanter with high efficiency is used for dehydration. The crude oil residue in the dehydrated slag phase can be recovered by the combustion or thermal desorption process. The separated crude oil is collected and then purified by a 3 phase disc stack separator. The purified oil can be reused.

Why Choose ZK Oil Sludge Decanter Centrifuge ?
-
Easy Operation
ZK oil sludge decanter can run continuously and automatically. The control of the decanter centrifuge is completed through the touch screen of the control panel, and the one-key start and stop of the decanter can be realized through the control panel. The control panel interface is simple and easy to be understood, and operators can easily monitor the working status and understand the operating parameters.
-
Durable
All wear-prone areas of ZK centrifuges (separation liquid outlet, solids discharge output, screw conveyor and solids discharge section) are made of abrasion resistant material, and the rotating parts are made of high-strength centrifugally cast stainless steel. For the wear-resistant requirements of special industries, replaceable hard alloy wear-resistant pieces are added to the spiral blades.
-
Lubrication Ways
In order to meet the actual needs of different customers, ZK decanter centrifuge provide three different lubrication ways (grease pump grease lubrication, lubricating oil circulating lubrication and oil mist lubrication) for customers to choose. All lubrication systems can re-lubricate the rotor bearings during centrifuge operation.
-
Safety and Security
ZK decanter differential speed automatic control technology can automatically adjust the screw conveyor differential speed, to prevent overload and blockage. At the same time, ZK decanter centrifuge has vibration protection, bearing temperature protection and overload protection system. This can avoid critical operating conditions and prevent damage to centrifuge components and bearings.
