The wet bulk storage slabs at some
bagasse pulp mills have rather elaborate
systems of drainage trenches with covers
for the collection of the return
transport water that drains through the
piles, as well as trenches for reclaiming
the bagasse in aqueous suspension. Such
trench systems are costly because of the
form work required and even more so
because of the corrosion protection
required. A much simpler solution is to
use as few trenches as possible and to
use slopes and depressed areas to guide
the return transport water to the
collection tanks. Form work costs are
then minimal and protective coatings are
easy to apply.
