Page 48 of 55 | May 2017 | 47 WATER MANAGEMENT: CASE STUDIES in appropriate waste disposal sites. In this plant, the treated water was successfully reused for hydraulic fracturing applications. The water management process and tech- nology must be economically sustainable to be adopted and used for long term. The GES technology for treating produced and flowback water has been projected to save about $450,000 for the operational timeline (Figure 4). Scenario 1 depicts the total cost to the operator if they would have chosen to dispose the water and source freshwater for hydraulic fracturing. Sce- nario 2 shows the projected cost and savings for treatment (including all associated costs such as energy, manpower, chemicals, etc.) and waste disposal. It is expected that the savings will con - tinue and even increase with enhanced volume of water treatment as projected by the operator. n 24 194 81 0 50 100 150 200 Iron Total Suspended Solids Turbidity Concentration (mg/ltr , NTU) Water Quality - Raw and Treated Raw Water After Treatment 0 200,000 400,000 600,000 800,000 1,000,000 1,200,000 1,400,000 Cost (USD) Disposal and Treatment Economics Scenario 1 Scenario 2 FIGURE 3.
