TYPICAL TREATMENT PERFORMANCE

NOTES:1) If TDS removal is required other technology such as reverse osmosis or distillation can be

applied.2) CFU- colony forming unit.3) Removal based on powered activated carbon added upstream of flocculators. 4) Metals removal has to be determined by running jar test then performing an analysis of metal of

concern on a representative sample at varying chemical doses.5) Removal performance of other specific constituents of concern not listed above can also be

determined by same procedure in step 4.

FRAC WATER QUALITY REQUIREMENTS:

WATER QUALITY REQUIREMENTS DEPEND ON WATER SOURCE AND FRAC CHEMICAL USED
