Davis <br /> Subject: RE: Sand Filter Question <br /> Alan, <br /> Since it has food service on the sand filter, I would highly recommend using the coarse filter sand specs from the <br /> innovative approval. The sand filter is much more likely to Clog with kitchen waste using fine filter sand. I also beIieve <br /> the ponding filter backs me up on this one. <br /> As to the sampling, I think you are okay with what you currently have. I don't see where adding FOG will really add <br /> anything. I think the BOD will give an indication about FOG and BOD. <br /> Let me know if you have any other questions. <br /> Thanks <br /> Trish <br /> Patricia M.
