Dear Benito,
You are right when the Seawater containing high quantity of TSS, Turbidity, SDI, TOC, Micro-Organism which is necessarily be removed prior to reaching Filter, UF & RO.
Whatever pre-treatement is applied better DAF in most cases; the output from pretreatment to be
TSS 12 - 15 ppm, Turbidity

Hi Mansoor,
thanks a lot. Yes I have the same understanding regarding Media Filter. So far I have taken 30 NTU as a reference value for DAF. But I am looking forward to get your feedback and see how is your experience with DAF.

Dear Benito, DAF is still widely used in case of high TSS/Turbidity and Algal concentrations. Media Filters get clogged very quickly in case no pretreatment is applied. I will send you some parameters values, let me look into some case studies.Regards,Mansoor Ahmed

Dear Mansoor,
thanks for your reply. What I am trying to find out is the value for each parameter. From which value is DAF recommended? I have seen recent plant being built without DAF in areas affected by red tide. So I wonder If there are new developments in Media Filter or UF, that makes DAF less necessary
