Hi Dharmendra, May I ask if you have any pre-treatment for your membrane? When you replaced the membrane did you notice excessive bio-fouling or scaling issues? A rapid formation of a biofilm colony or scale development is usually the answer for the decrease in flow rate. In this case, you will need to look at adequate pre-treatment for your membranes to maximize their efficiency. I specialise in RO pre-treatment in Asia and Australia, please email me at andrew@waterandoilsolutions.com.au and I'll be happy to see if I can help.
