Dear Avinash: There are two types of flux: Average flux is the result of dividing the total flow of water produced by the whole skid or individual vessel and the total membrane area of skid or individual vessel. This number although very used, does not give too much information, because it's an average. To have a real knowledge of what's happening, you should pay attention to the flux of each element in the vessel. (Each element product flow divided by element area) Several vessels with same average flux, can have very different patern of individual flux, depending on the type of membranes or their disposition ( Hybrid staging for example, gives lower maximum individual flux than standard staging, helping to reduce fouling)
