Abstract: An ion exchange system includes a first ion exchange column containing a first resin having an affinity for sulfate ions and nitrate ions that is greater than the first resin's affinity for chloride ions. The first ion exchange column is configured to pass a predetermined mass flow rate of drainage water therethrough. A second ion exchange column is connected in series with the first ion exchange column. The second ion exchange column contains a second resin having an affinity for chloride ions and is configured to pass the same predetermined mass flow rate of the same drainage water therethrough. As the drainage water passes through the first ion exchange column, primarily sulfate ions and/or nitrate ions are removed from the drainage water. As the drainage water passes through the second ion exchange column, primarily chloride ions are removed from the drainage water.

Abstract: A hydroponic water treatment system incudes a supply tank configured to receive water having contaminants dissolved therein. An irrigation pump is in fluid communication with the supply tank. The irrigation pump is configured to pump the water out of the supply tank. One or more above ground first containerized plant systems include a first growing container. A first plant having a first root system is disposed in a substrate contained in the first growing container. A first holding container is configured to contain the first growing container therein. The first holding container includes a fluid connection. The fluid connection is in fluid communication with the supply tank. The first root system is configured to receive a first portion of the water from the irrigation pump via drip irrigation and the fluid connection is configured to return a second portion of the water to the supply tank.
