Stedman had a design that took the solids off ahead of digestion and converted the removed solids to a fuel source. I liked this process as it pulled out a lot of material, which if it had gone through bacterial digestion, would have been converted into solution which is more difficult to control. Is anyone working along these lines? I ask because a lot of the pharmaceuticals are broken into more toxic daughter products either by bacterial digestion or later oxidative processes, and many are mitochondrial toxins (MT). Thus using the effluent as an irrigation source or drinking water augmentation sees these MTs bioaccumulating in irrigated crops or being chronically delivered with drinking water.

Kindly attach the detailed characteristics of the effluent at inlet of digestion unit.
Agree with Shahul. technology for removal of solid from effluent depend of nature of effluent and the presence of chemical and biological constituents
The plant is a typical municipal secondary plant treating 8 million gallons per day, and equipped with a 4.3 million gallons per day Tertiary Treatment for recycled water. The idea is to suggest sending a cleaner influent through plant by removal of solids up front. This would substantially diminish bacterial digestion of solids, including pharmaceuticals. Plant is down-gradient from level 4 teaching hospital and surrounding labs and other clinical facilities. Recycled water is slated to be augment source for groundwater recharge. A cleaner end-influent would presumably make the raw stock becoming recycled water less of a hazard and easier on equipment.
