Predicting Product Water Quality from the 600-Gallon-Per-Hour Reverse Osmosis Water Purification Unit. Field Water Supply on the Winter Battlefield

摘要

A preliminary equation for predicting the total dissolved solids (TDS) concentration in the product water from the 600-gph ROWPU is presented. The equation requires the raw water temperature and TDS concentration as input data. Both of these variables can be easily measured in the field. The equation is presently limited to raw water TDS concentrations in the range of 800-900 mg/L. As data become available for a greater range of raw water TDS concentrations, including seawater, the equation will be modified. The standard error of the estimate is 3.4 mg/L.
