Advance Oil/Solid Separation
Introduction
(Tilted Plate Pack) Systems
The phenomenon of "Garvity Sepration" is used by engineers
extensively for separating the solids from the liquid or fluid as the
case may be .
It is therefore apparent that material with high density will settle
and with
lower float to the surface of fluid. However, the effectiveness of the
technique is subjected to various factors such as difference in the density,
viscosity,
factors of the medium, temperature, turbulence, and also the nature of
impurity etc. In some cases chemical coagulation and flocculation is
needed for removal
of the impurity by making them heavier or lighter. In separation technique
while considering the above referred factors, which affects the separation
of impurity, an overflow rate (m3/m2/day) or setting velocity (m/hr)
is arrived at, which inturn determine the surface area required for the
gravity
separation.
Incidentally it proves the fact that it is independent of the depth of
basin.
The gravitational system offered by paramount with technology acquired
from m/s. PWT, Holland provide an extensive reduction in surface area
requirement of a separator by introducing multi layer separation wherein
area required
is reduced considerably depending upon number of such layers. It is feasible
to achieve almost complete removal of all the particles which would not
have normally be achieved by a single large surface separator. This is
possible because of considerable increase in the surface area of the
unit, within the same depth. In most of the cases the plates are installed
at
an angle of 45°deg. or more and thus the separated material can be
collected and removed by gravity.
Significance
The corrugated plate pack is the heart of our various purification system
consisting of number of parallel corrugated plate. These are framed in
a housing of fault plastic plates and then is stiffened by frame made from
plastic material and/or stainless steel.
