Trying to find the optimum liquid phase activated carbon bed depth for acid wash carbon (12 x 40 mesh). Is there such a thing as a maximum bed depth in a vessel. If so, what is the limiting factor (i.e. backwash flow, compaction of carbon, pressure drop, etc) ?
Does anyone have experience/data regarding Brine Energy Recovery devices (i.e. ERI turbo) used on Brackish Water feed (not Seawater). Is it cost effective for a brackish water feed water or 2 pass RO application?
Does anyone know what the maximum recommended freeboard height to accomplish backwash of a single bed ion exchanger. I have observed industry standards for minimum freeboard at approx. 75% based on 50% bed expansion, but I have not seen guidelines for maximum freeboard and the impact.
