... & grease not higher than 1 mg/l and 10 mg/l, respectively, at all times during the test period. Therefore, it has been proven that the ceramic membrane filtration can be very effective for alleviating plugging risk when applied to PWRI in tight reservoirs. Silt-density-index (SDI) of permeate, an indicator...

... of divalent ions and depletion of monovalent ions. Dual media is used for oil removal from PW. De-oiled PW is feed for Nanofiltration (NF) membranes for separation of barium and calcium ions. Combination of NF retentate with seawater (SW) as feed and NF permeate from PW is also considered. PW permeate...

... filtration processes A principle known as crossflow filtration is the most common membrane filtration configuration. The flow of liquid in crossflow filtration is parallel to the filter, while the filtrate or permeate flows through the filter. The flow of liquid results in shear stress and turbulence along...
