Abstract
The disclosed principles for providing a chemical-free filtering of particulate down below sub-micron levels, while concentrating the particulate into a sludge. The disclosed principles integrate cross-flow filtration (i.e., micro-filtration or ultra-filtration) with a settling tank (or “weir”) to provide sequential filtration and dewatering of an aqueous media. The disclosed technique operates chemical-free and is continuous. Applications for systems and processes in accordance with the disclosed technique are wide, and include aggregate fines removal, sediment removal, replacement for clarifiers, etc.
