This powerpoint presentation presents a project by the City of Plantation, Florida, to identify an alternative water source. Indirect Potable Reuse -Aquifer Recharge was chosen. Issues for consideration in the selection of groundwater recharge through surface water discharge with the Plantation pilot included: nutrient control; MBR scheme data; conventional treatment scheme data; microconstituents; and, aquatic organism impact toxicity. Presentation summary indicates: the pilot demonstrated to meet stringent nutrientlimits at different test conditions;RO membranes are necessary for surface waterdischarge due to stringent TP limits;almost all microconstituents were removed byRO system;RO permeate could be toxic re-stabilization/remineralizationis necessary; and,the observed toxicity to aquatic organisms was likelycaused by chloramines. Other forms of RO pretreatmentshould be evaluated. Includes figures.
