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.
