The problem is that the disposer thrusts out waste material with
sufficient force that it doesn't fall down the "T" immediately --
instead it gets thrown into the other sink. A better solution would be
to use an "L" from the disposer output to send the stuff straight down
to the trap. In the vertical run to the trap you may be able to use a
"T" for the second sink drain. The combination of gravity and no bend
from the disposer reduces the likelihood of waste backing up into the
other sink. However, it appears that the drain line to the wall is too
high to accommodate the "T," so double traps may be the only solution.
Just have the disposer output take a straight shot to the wall.
