Claim:
1. A method for treating a fluid, the method comprising: injecting influent into a crystallization precipitation reactor, wherein the crystallization precipitation reactor comprises a vessel containing a media and defining a lower portion and an upper portion, the influent injected into the reactor proximate the lower portion of the vessel via a first conduit, the flow of influent in an upward direction relative to the reactor; discharging effluent from the reactor proximate the upper portion of the vessel into a suspended solids polishing device; and injecting recycled effluent from the suspended solids polishing device into the reactor proximate the lower portion of the vessel via a second conduit, the flow of recycled effluent in an upward direction relative to the reactor, wherein one of the first and second conduits injects fluid into the reactor through the bottom of the reactor at a position substantially located at the center of the bottom of the reactor, and wherein the first conduit and second conduit are concentric relative to each other and define concentric and parallel flows, wherein the first conduit and second conduit are in fluid communication with the vessel, and the influent within the first and second conduits do not contact each other until they have made contact with the media in the vessel, and wherein the concentric flows do not contact the media in the vessel until they exit the respective first and second conduits, and wherein the flow from the first and second conduits maintains consistent hydraulic loading of the reactor.
