Abstract: The present invention relates generally to a method to determine one or more properties in a water storage facility and/or a water treatment facility. In one embodiment, the present invention relates to a method to determine one or more chemical and/or physical properties in a water storage facility vessel and/or a water treatment facility vessel and then use such one or more chemical and/or physical properties to determine where, if need be, any sand or other sediment needs to be removed from any such water storage facility vessels and/or a water treatment facility vessels.

Abstract: Provided is a method and system for separating components of a solid and liquid mixture. In an embodiment, the method includes de-sanding a treatment system. Digesters, clarifiers, wastewater apparatuses, self-contained processing tanks, process tanks, and the like, accumulate sand and other undesired inorganic components that ultimately prevent filtering, cleaning, and processing of the solid and liquid mixtures therein. The mixture in the treatment system may initially include sand, water, and biosolids. The mixture may be routed into a pressurized tank to separate the inorganic solids and liquid components based on their density and buoyancy. A de-sanded mixture may then proceed through the remaining cleaning process.
