Dear Raphael, You are going to treat surface water. Here the main culprits are colloidal particles, organic matter and colloidal silica. What pretreatment have you considered for your pilot studies? Get test done for colloidal silica too. For your second trial consider using Uf as pretreatment. In case of colloidal silica ,go for 10K MWCO uf module. Also what are the parameters for your pilot studies. What SDI has been considered for your plant design ant what is the sdi of your feed water to ro? what is the flow, array and recovery considered? You may write to me at ashwin@aquafilsep.com or may post your results and observation in the discussion. Regards Ashwin Doshi
