My experiences with small ...
Published by Gary Brown, Water Practitioner at Dikubu Water
My experiences with small plants and fluctuating loads has shown best and most consistent process performance with attached growth systems rather than activated sludge, or suspended growth, exactly for this reason of fluctuating F/M ratio, since the operating responsibility usually lies with the resort or hotel that has little skill in applying process control to respond to changing load. Across Africa and the India Ocean Islands, I have had lots of success in applying rotating biological contactors (RBC) as a process that seems to be very resilient to fluctuating F/M ratio due to the nature of the installed process. MBBR should give similar consistent performance. Another key attraction of RBC is the low sludge yield, again reducing the skilled operational input required.
I will gladly assist if you require additional support, since effluent qualities and utilisation needs to be understood - i hope that at a resort effluent re-use/recycle is being applied.
Good luck
