To some extent. The Dow guy I talked with said increasing the flow away from the mb would reduce the fouling rate....this is more gallons through the flow meter of gallons pumped or circulation but it would not neccesarily increase my permeate flow.
One needs to remember we are not using this mbs as originally designed. What we want is the throw away product for their original design. This are desalinization mbs. So when we want more sugar we are really looking at decreasing the concentrate flow to remove more water for discard. For a water plant they just pump more sea water through the mb and it is at no appreciable cost. For us it is more water that we need to pump back through the system to get rid of.
But one could make a case for a large pump on a VFD that you could press B and the pump will spin at full rpm and flush the mb of lodged sugar. Drives for small pumps are in the $150 range and would work well for that purpose. One could also adjust the drive to adjust pressure. As far as that goes with a bit of wiring and pressure transducer one could make the unit adjust its own speed to get the most out of a run cycle. Add in a sugar meter on the permeate and if sugar were to pass then it could do an auto flush cycle.
But now we are getting out of our budget perameters for many people; but the options really are all the way to a unit turning on and off as set by the operator and all one would need to do is manually change filter cartridges...set of several so that if output pressure dropped the unit would switch to a new filter housing by way of elec valves.
