Erosion Park Service

Water erosion is the process by which water moves sand or soil from one location to another Water erosion may change the environment

Slow Sand Filtration for Water Treatment

• For slow sand filtration systems site specific pilot testing is necessary unless a slow sand filter is already treating the same source water at another location because understanding of these systems is insufficient to allow engineers to predict what filtered water turbidity an operating slow sand filter will attain Piloting of these

Sand Washing/Dewatering DM

When dewatering the equipment uses a mechanical action to separate the product from excess water This equipment operates using similar inputs in the setup Material that enters the equipment will be divided into 2 flows being a product and an overflow
