Inclined Plate Clarifier for Potash , Albite Feldspar Sedimentation
The Inclined Plate Clarifiers is a highly effective multistream
parallel plate clarifier. The Lamela plate separator is based on a
proven and efficient plate sedimentation technology of removal of
contaminants from municipal and industrial waste waters, widely
used for years in water treatment stations all over the world. The
use of the plate sedimentation process has made possible to save
about 90% of the space in comparison with the traditional
horizontal sedimentation tank.
The Lamela separator can be delivered as a fully assembled
self-contained unit or as the plate assembly for installation into
e.g. concrete tanks.
The plate assembly incorporated in the unit comprises a set of
interconnected plates inclined at 55-65 degrees, made of plastic or
steel to assure durability and low weight. As standard, the plates
are spaced at 50-80mm one from each other to assure rapid and
effective separation of suspended solids while using only a
fraction of the footprint of the traditional sedimentation tanks.
At the same time, the separation of suspended matter using plates
assures far higher efficiency while the added lower sedimentation
tank allows better dewatering of the sediment.
Selection of type and model is often determined by pilot tests on
the investment site.
Preconditioned feed with entrained solids enters the stilling
chamber removing kinetic energy. All solids begin a downward flow
in the now quiescent water. After flowing through the sludge
chamber the feed is forced upward through the plates. This is
referred to as a counter current flow pattern.
As the flow rises between the plates the heavy solids (with a
specific gravity higher than the surrounding water) will settle
onto the top surface of the lower plate and slide down the inclined
surface to be collected in the sludge hopper.
Clean and clear effluent, flows to the top of the plate area and
decants over an adjustable weir. Solids are intermittently
discharged from the side of the sludge chamber with an auger.
Depending on the application an optional solids recirculation
system may be integrated into the design to optimize separation.
· Carbon steel tank, excellent resistance to corrosion
· Vertical installation, compact structure with small footprint.
· Easy to install and maintain.
· Slant plate clarifier is widely used to remove ion, solids and to
reduce turbidity, easy to operate.
