Dharmenda I would have to agree with Andrew and add a possibility of flow restriction on your pre-treatment if you have one. (Filters being plugged) You did not mentioned if you have scale inhibitor injection(s). You may want to look at your chemical injection system(s) to make sure you have a proper dosage for your anti scalant, sulfuric acid etc.... Also, you did not mentioned anything about your influent temperature. Lower temperature require more power to produce same flow through your membranes than higher temperature.
