Environmental Dredging

Environmental dredging usually refers to the process of removing sediment and debris from rivers and streams. With the continuous sedimentation of sand and silt in the river channel, the riverbed will rise and even produce many algae, which will cause serious damage to the water environment and even lead to the normal navigation of the channel. As a result, these deposits must be cleaned regularly. The decanter centrifuge plays an irreplaceable role in the treatment of sludge and algae.

ZK SEPARATION Decanters for Environmental Dredging Process

When carrying out environmental protection dredging of rivers or lakes, an important link is a solid-liquid separation, namely dewatering. We use dredgers to remove sludge or algae in the river. We must treat these sludge or algae to meet environmental protection standards. When dewatering the sludge mixture, the large-capacity centrifuge is undoubtedly the best equipment. By adding polymer to the mixture to make it unstable and increase the particle size, then the sludge mixture is sent to a centrifuge for treatment through a pump, resulting in a relatively dry filter cake and relatively clear wastewater. For oily sludge treatment, a three-phase centrifuge can be used as a treatment system, which can effectively separate the three-phase mixture of oil, water, and sludge.

Why Choose ZK Decanter Centrifuge ?

  • ease to use decanter
    Easy Operation

    ZK 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
    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.

  • security
    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.
