Fluid treatment system having concentric chambers

Abstract

A system and method for treating fluid by providing a series of concentric chambers, tanks or tubes so that a fluid flow and treatment efficiency is maximized while size, complexity and cost of manufacture and operation is reduced. In one aspect, a generally non-turbulent fluid flow is received and directed in a radial sequential direction through the series of chambers. Each chamber is configured to house a filter assembly or media that provides a level of treatment for the fluid flow while directing the fluid toward a subsequent concentric filtration chamber. The last sequential chamber directs the fluid flow toward a fluid outlet and reduces the turbulence of the flow generated during the filtration process. The system can be configured to direct the fluid flow in inward or outward radial directions according to various arrangements and during filtration or back flushing operations.
