Dear Sir, in our experience ...

Dear Sir, in our experience it is highly unlikely that you need a DAF system to produce a water suitable for a following Reverse Osmosis membrane plant. Direct filtration using pumice with a very small dose of a primary coagulant is more than able to produce a water which is acceptable to membrane manufacturers. Direct filtration would be a much simpler and cheaper alternative. However, if you do wish to continue to go down the DAF route then please let me know as we have access to high rate and simple to operate DAF technology.
