Think again Dicky...
Let's put it another way. What causes sludge to form? It is not in[/i] the water. It comes from somewhere and is transferred to the settlement area (whatever it may be on a system) by the water. The water also plays a part in the forming of the sludge.
So... Where/what is this "somewhere"? Sludge is a bad thing regardless of where it settles, and surely a known, single settlement area that is relatively easily clean is better than a dozen rads that need flushing or removing and flushing.
Come on fella - you know better than that.
Please enlighten me DR. Cause I can assure you that there's always much more sludge in a sludge bucket system than a standard vented or sealed system. And there's always a much larger volume of water in a sludge bucket system.
