The introduction of hydro-vac slurry to the trommel.
This initial process will efficiently wash and remove all gravel material larger than 1” where its falls into a bin for stock piling.
The large gravels may carry a small percentage of moisture contained within any large clay pieces and organics.
The material is further processed in the centrifugal dryer system where the water is removed for further processing where the small aggrigate, dirt and fine material recovered for reuse. The adjustable moisture content of this material discharged is as low as 5%.
The sand and fines removal are done with shaker processing. The material discharged from this process is primarily sand with trace amounts of fines. This product carries a workable moisture content and is stackable.
During the centrifuging and final solids removal process, the clays and fines are collected for reuse or disposal. The centrifuged material contains the highest moisture content with a typical range of 30-40%. This product can be homogenized with that from the dryer to provide a stable fill product.
The water recovered from the Hydro-Vac material is flocculated in real time. The distinct advantage to this immediate processing means the water is quickly ready for reuse within the processing plant and back to the Hydro-Vac trucks. After processing, the recycled water will average +150ppm of total dissolved solids than source water.
The footprint - this site footprint can scale up to accommodate increased throughput to keep pace with a demanding project schedule.
