Cenovus SAGD Filters
The SAGD or steam assisted gravity drainage process has become a popular oil production method in Alberta. After the oil is produced, the treatment process begins with electrostatic dehydration, high efficiency gravity separation, and floatation. The Deep Bed Filter is then implemented in the Oil Removal step (ORF), prior to lime softening, and the Softening step (After Filter), post lime softening.
At the Foster Creek site, the oil water filter influent is between 100 ppm and 300 ppm with an effluent less the 3 ppm oil and solids. The softener is then used for solids removal and polishing before ion exchange. The softener effluent is consistently less than 1 ppm TSS. Using these SAGD water treatment units in both steps continues to be a viable option for oil producers in Canada.
