Abstract
The treatment system at Sunset Ranch Development in Homedale, ID, consisted of one Point of Use (POU) reverse osmosis (RO) unit each at nine participating residences to remove arsenic, nitrate, and uranium from source water. Softening of source water was performed as pretreatment to meet the feed water quality requirements for the RO units. Six Point of Entry (POE) softeners and nine POU RO units were provided by Kinetico. Each POU RO unit consisted of a 20-mm pre-filter, a RO module with a 1.7-in-diameter by 11-in-tall, thin film composite, semi-permeable membrane element, a 3-gal storage tank, and a MACguard post-filter. The RO units were capable of producing up to 35.5 gal/day (gpd) of permeate water and had a feed water to permeate water ratio of 2.7 to 1, a 37% recovery rating. The RO units automatically shut down the production after 500 gal of permeate water have been processed and resume operation only after the replacement of pre- and post-filters.
