Abstract:

The invention provides systems and methods for removing perchlorate from water. The systems comprise reactors comprising biomass for degrading perchlorate, and the operation of the systems can be controlled according to novel logic specifications. Also provided are filters and filtration systems for clearing water in advance of analysis of the concentration of contaminants within the water. The filters comprise a length of tubing configured to generate backpressure at the filter sufficient to facilitate the flow of a water sample through the filter without overpressurization.
