The company who provides the environmental protection service may have this company for dredging in canals or lakes. Many years’ soil sedimentation down to water bottom, leaves falling in the water and then rot, as well as the trash threw into the normal water will make the river mattress higher and higher which leading often the pollution of the water and also the cutoff of the water flow. Therefore , we need take action to take out the sand, silt and trash at the bottom connected with water to make the water clear.
To take the solid things out from the water, we need a good and liquid separation system to do this job. As a foremost manufacturer of solids control equipment, GN solids control luckily jointed a project to really make the lake water clean really residence district. There is a dredging boat that can take the strong mixed with water from bottom level of the lake, the grubby slurry was sucked away and delivered on to the property with smelly smell.

The actual slurry is fed using a steel wire box just where large size solid stuff will likely be blocked and collected. Then your liquid will be pumped to be able to GN’s solids control system. In this system, GN created 3 stages for solids control including shale shaker, de-sander and de-silter. The de-sander and de-silter have underflow shaker that could stumble through discharges from cyclone considerably dryer. After treated with the de-silter cyclones, the sturdy stuff with size bigger than 15-20 microns will be eliminated. And the rest solid from the slurry is difficult to eliminate by using mechanical machinery.
Flocculation is a good method to gather often the ultra fine solids within the slurry. Add the flocculation agent into the slurry depending on certain ratio and then entirely mix with agitators. The flocculated slurry will need several times with regard to sedimentation and then will be streamed to belt filter click for final dewatering method. The solids will be dismissed with a thin cake design, and the water could be wiped away directly back to later or maybe river.
The advantage of the filtration system press is to make the solids much dryer, and negative aspect is high cost and modest treating capacity. Some other service provider will use decanter centrifuge to try and do the final dewatering job with consideration of its much larger treating capacity.
