Michael , Good to hear you. We have no more space , we can just coagulant dosing before MMF and After feed pump 3 inch PVC line , Otherwise have no other option due lack of space availability . Please suggest best of the best coagulant available in market. However, Our First pass R.O has 4 inch 1 micron membrane AD-90 Model  GE brand  like ultra filtration membranes , only change in Passes, First pass R.O has three passes for converting 12000 ppm to < 100 ppm TDS , PD Pump Pressure 35 Bar, Furthermore, SDI mostly After ( MMF+ACF+10 Mirco Bag filter is) above 3.
