Recently we finish the construction waste management system commissioning, and now the whole system is alive operating. The basic principle is still the same, we are separating the solids and liquid. As for this specific project, the client is collecting many different kind of waste from civil construction projects. 

 So here is the separation hub, when the trucks bring waste, any kind of; they dump to the hopper which designed under a deck for easier operation; follow the hopper, the waste goes to the coarse shaker, equiped with robust steel wire sieves, to separate the big size particles. The next step is a GN normal shaker, with finer mesh hole size, to separate the smaller solids, then to desilter, to centrifuge, same story, through tank, feed by pumps. 

 For this specific application, Hi G dryer shaker have been used. On one mud tank, GN’s high G force drying shaker is fixed on the first compartment of the tank. The liquid pumped from the tank beneath the coarse screen will be separated again by the drying shaker for fine particles removing and water recovering. For better performance, GN’s shaker is fixed with composite frame screen panel and oil resistance rubber seal strip. This extends the continuous working period and reduces the maintenance frequency. 

 As to help the performance of decanter centrifuge, it comes with a dosing tank, adding polymers to thicken the silt and make it easier to separate. the decanter centrifuge is provided with telescopic skid. The slurry treated by the cyclone unit would be fed to the centrifuge for polishing. The ultrafine solids cannot be removed even by high speed decanter centrifuge.
