| Title: |
Use capacitive deionization to filter produced water |
| Text: |
"Capacitive deionization is based on an electrostatic process operating at low voltages and pressures. Produced water is pumped through an electrode assembly. Ions in the water are attracted to the oppositely charged electrodes. This concentrates the ions at the electrodes, while reducing the concentration of the ions in the water. The cleaned water then passes through the unit. " |

| Cost-Benefit Analysis: |
“Capacitive deionization offers more cost-effective performance than other types of salt removal technology (e.g., reverse osmosis), especially when the produced water is not highly salty or the treatment goal is not geared towards achieving drinking water quality.â€
and...
“Atlas (2006) more recently suggested that treatment costs could range from $0.05/bbl (for produced water with a TDS of 10,000 ppm) to $0.20/bbl (for produced water with a TDS of 2,000 ppm).†|
| BMP Efficacy: |
“The backwash stream from capacitive deionization treatment of produced water will contain high levels of sodium and chlorides. It is therefore advisable to consider disposal requirements for the concentrated brine when selecting ion exchange treatment.†|
