Abstract
A water clarifier for removing sediment comprises four successive compartments in which settling of the sediment is provided and clarified water removed. In three of the compartments, sediment contaminated water travels through a tortuous path to cause the sediment to settle to the bottom, forming a sediment bed in which the water is filtered. Sump means are provided to remove the sediment. Substantially clear water is directed from the third compartment to the bottom of the fourth compartment, pure water is exiting the fourth compartment near the top thereof and at the end of the compartment opposite the end at which the water entered. The clarifier is mounted on an easily transportable vehicle and is capable of treating approximately 150,000 gallons of contaminated water per day in which the water to be treated can be pumped directly from its source and the clarified water leaving the fourth compartment returned, thereby substantially eliminating excessive loss of treated water.
