- Sink float tanks are installed in almost
all plastic recycling systems.
- Most of everybody call them "washing tanks"
but, unfortunately, tanks are not washing anything.
- To better explain what we're talking about just
get a dirty flake of any kind, put into a glass of very
clean water and leave it there for few hours.
- If you find it clean please give us a call
because we'll be really surprised.

- Yes, a tank is a tank
so what's the deal with it ?
of everybody, mainly "beginners" did their
own construction simply because everybody is in position
to put together a tank.
about a tank that will handle, as main material, a floating
one, what everybody find out is this tank does not separate as
much as it was supposed to, just because all parameters should be taken into
consideration and they wasn't.
ratio between the surface area of the tank and the volume
of flakes in the unit time.
apparent volume of flakes (when dry)
density of each material (the good one and contaminants)
speed of the water on the surface of the tank.
capacity of dewatering system at the end of the tank
way the flakes are fed into the tank (on the surface
or under it)
turbulence of water under the surface
angle of the sides connecting to the bottom
clean the water inside the tank is
this as far as technology.
it goes to motor-reducers set up, screw conveyors dimension
and speed, size of screens, pumps dimension and impellers
shape, valves, level control etc. what it comes up is
normally something messed up.
to mention if rolls with sprockets and chains are mounted
to make it "better performing"
it is true that a tank is only a tank, but a trouble-free,
efficient one, is another kind of device.
