Hi Scott
what do you mean by placing kaldnes inside a separate unit within the vortex?
could you show me the pictiure?
if i'm not mistaken someone said that kaldnes work well in his vortex..

i plan to put 50 litre k1 in my vortex

rgds,
teddy

It started out as a settlement with nothing in it and was later converted to house the Answer. I removed the Answer and first placed static kaldnes floating free in the vortex. This proved to be problematic and coarse waste was mixing into the Kaldnes and I was having trouble removing it. After placing the kaldnes inside a separate units within the vortex this problem was solved. Do you want fines separation of biofiltration? For separation of fines you want no movement of as little a possible. I placed a single brush in my vortex to prevent the water swirling about the containment vessel I do have a second chamber with fluidized Kaldnes. To do this it is absolutely necessary to be able to filter the coarse waste out of the water BEFORE in enters the fluid kaldnes. In the fluid kaldness bay you need to look at a few things. You must keep the Kaldness from entering the next chamber and you must prevent it from being flushed back to the previous one. The area where the water transfers to the next chamber must be quite large to prevent the kaldness from packing onto the device that retains it.. I.e. if the water is flowing with too much force the kaldness with stick to the screen and cause the next bay to be sucked down too low. This is another reason for prefiltration of coarse waste as this will do the same.. Last of all you need to pump air into the chamber beneath the Kaldnes to make it circulate and not float on the surface. The added air also aids nitrification. In a fluid set up you want vertical circulation. the water spinning doesn't matter one way or the other. It won't help but won't hurt either. B.Scott
