2. ALIT Technologies’ FASTRIP FP
filtration systems are the perfect response
to this need. They feature a filter press
that separates the paint sludge from the
paint stripping solution, so that the filtered,
purified solution can be recirculated to the
stripping tank.
The solid waste, on the other hand,
is pressed into sludge cakes that are
collected and disposed of separately.
The paint sludge extraction rate, i.e. the
kilograms of sludge removed from the
bath per day, and the quality of the filtered
liquid sent back to the stripping tank are
two key factors in maintaining the paint
stripping bath’s best performance level.
ALITFLOCK 4840 handles them both,
because it improves both the paint sludge
removal rate and the quality of the filtered
paint stripper.
ALITFLOCK 4840
ALITFLOCK 4840 is an adjuvant in the filtration process of
paint stripping baths, as it greatly improves filter presses’
efficiency and productivity when treating exhausted,
contaminated baths.
Such efficient filtration is often a key factor to make paint
stripping a cost-effective process. During a cycle, paint is
removed from workpieces and progressively accumulated
in the paint stripping bath. The higher the amount of paint
sludge dissolved in the bath, the greater the problems,
because it translates into longer cycle times and more
expensive processes.
Higher volumes of sludge also mean that the liquid is more
viscous: this can pose a risk of tank heating and liquid
dragging, which again translates into greater costs.
An increased amount of paint sludge can also
generate a crust that may clog the hydraulic circuit,
pumps, and pipes, thus calling for higher
maintenance costs. It is therefore clear that
the regular and efficient filtration of a
paint stripping bath is crucial for
cost effectiveness.

FLOCCULANT DOSING DISPENSER WITH AVIBRATORY CHANNEL
ALIT Technologies’ flocculant dosing dispensers have been specially designed and sized
for the automatic addition of flocculant to tanks containing paint stripping sludge. We offer
different sizes of dispensers depending on the type of paint stripping equipment. By means
of a special vibratory channel, they enable an ALITFLOCK series flocculant to be reliably
transferred from the vibrating hopper to the sludge sedimentation tank, where it is mixed
by the pneumatic mixer. The dosing dispenser’s hopper is equipped with a level sensor
that signals when the minimum product level has been reached. It is possible to adjust the
automatic dosing parameters by operating directly on the filter press’ panel interface.
