Dear Ian: Thanks for your mail. We have observed a range of 5% to 10% of blow down,however, % recovery and comparison vs conventional and DAF is application specifics. Best we can do for refrence is to describe on a qualitative way what we can expect. Please take a look on these two videos so you can get a better idea. - https://www.youtube.com/watch?v=RiQZ46twn38 - https://www.youtube.com/watch?v=CIHw4JJzE_A   Our set up allows to have a dynamic solid control, similar to a cooling tower blow down that actuates a blow down based on a set point of conductivity in order to control cycles of concentration. During local pilot runs on lake water, We could concentrate very easily NTU from 2.0 to 500 NTU with no com0plications, membrane cleaning each week. In any scenario, a compromise need to be established on local conditions so we can balance the specific objectives of the process (reduce NUT,TTHM..etc.), trans membrane pressure, filtrate rate and the frequency of membrane cleaning. There is a good chance to reach zero liquid discharge since the blow down can be routed to a unit that separates solids from the liquid The beauty of our solution  is that there is a protocol to be followed in order to guarantee results and protect clients best interests. 1 samples are sent to our corporate offices for a preliminary assessment 2. budget estimates are presented to client, if accepted 3. pilot trials are run on the site 4. actual units are deployed and commissioned, results are double check   Additional notes - system can operate with solar panels inside a trailer 20 x 30 ft - DAF needs a down stream filtration system, we don't - our system is compact and requires at least 50% less space as compared with coagulation / floculation / sedimentation basins Let me know if more information is needed gitpr@gitpr.com
