This is a repeate order, 3rd order, firstly should congrates the client, they are expending their business, and then thanks for them to choose GN product, once again. In another way, it also proves the importance of a practical customized system.
This sytem contains 3main modules:
1. Waste Collecting and Washing Module – the waste slurry is delivered to site via the hydrocac truck and then discharged to a large size collecting hopper at which bottom there are valves to discharge the slurry onto a coarse screen for large size trash separation. The liquid with fine particles is collected in the tank located under the coarse screen. The liquid is then pumped to GN high G forcedrying shaker for finer solids separation. Here the operator can also use pressure flushing device to wash the slurry. GN shaker is fixed with composite frame shaker screen for longer working time and better performance.
2. Fine Solids Hydro cycling Separation Module – GN desilter with hydro cyclone manifold is fixed on a washing tank for further separation of the fine solids. The under shaker of the desilter is same model with GN drying shaker for easy maintenance. The hydrocyclone is using centrifugal force and gravity to separate the liquid and solids. The slurry is pumped into the cyclone with high speed for effectively separation process.
3.Dewatering Centrifuge Module – in this hydrovac excavation waste slurry treatment system, a 22 inch big bowl decanter centrifuge is used to remove the ultra-fine solids in the slurry. A chemical dosing system can be connected to the dewatering centrifuge to increase the efficiency of the separation.
Though basic idea still same, and been there for hundreds of years, each site is different, everyone is experiencing different projects, and having their own preference. Buying equipment, buying a solution is buying a way to get rid of hassels, all the small changes, all the design details matters.
All we need, except actually produce something, is helping client to save operation cost, saving manpower, saving all comsumption, in a safe and environmental friendly way.
