Toro Equipment Settling Tanks
The function of the lamellar settler is to remove suspended semi-heavy and heavy particles (grit, clay and lime) from the water. These elements hinder subsequent treatment by producing deposits in hydraulic conduits, piping and channels and causing abrasion to pump impellers and equipment etc.
In the decanter it is where solids are separated from the treated water. This separation is done by simple gravity, being solid, higher density, which settle to the bottom.
Toro Equipment manufactures defender® lamella settler in Carbon Steel and GRP and W-Tank® settling tanks in GRP.
W-Tank® Settler
The plates of settler W-Tank® are manufactured by flex molding process.
The Flex Molding process is used to obtain reinforced plastic pieces with high glass fiber content, arranged in the direction of the stress, which leads to high mechanical strength.
It consists of injecting a reactive polymer under pressure into the mold which contains the reinforcement in form of fibers, all of which is done in a controlled vacuum environment.
This process of impregnation (Flex Molding) is used to build pieces in a closed mold, making it an ecological process by eliminating emissions and consumables.
Defender® Lamellar Settler
Lamellar settler is designed for the continuous separation of sediments from water and they have two basic purposes: to increase the settling area and to obtain a laminar flow.
The concept of the lamellar settler is based on the fact that the surface load (m³/m²/day) of a freefall settling tank does not depend on its depth. It is therefore possible to increase the capacity of a settling tank by dividing it, there by creating a number of “settling tanks”, or by using plates inclined at a certain angle.
