| The BD circuits should each feed some type of mechanical seperation stage followed by one or more biological conversions stages. Personally I would not consider a passive vortex as worth having. Now if that vortex has a VMS, static K1....to GREATLY increase the capture of solids....great. There is a huge different!!!!
Now for the bio conversion stages.....hard to beat a good fluid bed followed by a static bed of K1 or maybe some Japanese matting. |
