Filtration efficiency for oil field injection water took a big step forward by combining flocculating chemicals with a unique upflow filter design. Minute concentrations of high polymers (polyelectrolytes) cause flocculation of undissolved solids in the sand bed of a new upflow filter to improve filtration characteristics. The upflow filter design is a unique departure from conventional filtration methods. The basic design was developed by the Impacti Co. of Amsterdam. The Netherlands, and licensed to The De Laval Separator Co. whose commercial unit is call the Up-Flo/ Immedium filter. The upflow principle along with bed composition permits retention of relatively large amounts of solids. The polyelectrolyte chemical is believed to charge the suspended solids or colloids which tend to flocculate on the surfaces of the sand bed. Since the flow is up through the coarse layers of the bed into the fine sand layers, more of the solids are entrapped before flushing is required. This application is critical offshore before produced brine can be discharged into the open sea.
