Re: [biofuel] Pool Filters for WVO/alternatives/toilet paper
Brian, On the surface this would seem better...but all filters tend to clog and either require frequent changing or a backflush capability. Although toilet paper rolls would be a cheap alternative to real filters if you need to filter to say 5 microns (as is suggested for WVO/SVO you still need a final real filter. And then there is the time and mess associated with changing out fouled disposable filters. For filtering serious amounts of WVO I found the least expensive and most productive way was to use reusable filters and a simple inexpensive backflush cycle. Automating it just allows the maximum utilization of the filters with a minimum of tending. 400-600 gals/day should fill most small producers needs. Keep contributing Brian...there are no stupid questions or suggestions. I am sure that the method you suggest does exist and will fit some folks needs well.

Re: [biofuel] Pool Filters for WVO/alternatives
The biggest problem with these flat downflow filter systems is the crud and water quickly cover over the filter area and block it. If you want to try it I suggest putting a small slope on the filter with a trough along the lower side to collect the water. or run the oil upward through the filter like the glass bowl petrol filters do.
