Fluid control method

摘要

A treatment control system using a fluid using system wherein fluid is passed from the fluid using system during dump cycles occurring at periodic time intervals over a total dumping cycle. The fluid passed from the fluid using system during each dumping cycle is sampled and designated as a fluid dumping sample with each fluid dumping sample corresponding to the fluid passed from the fluid using system during one of the dump cycles. The total dissolved solids level in each of the fluid dumping samples is determined. Some of the dump cycles are designated as discharge cycles or treatment discharge cycles where the total dissolved solids level is above a predetermined high total dissolved solids level. Some of the dump cycles are designated as reuse cycles or treatment reuse cycles where the contaminant total dissolved solids level of the fluid dumping samples were determined to be below the predetermined high total dissolved solids level. The fluid is discharged or treated and discharged or reused or treated and reused in accordance with the determined cycle designation.
