Deep Cone Clarifier vs. Rake Style Clarifier

Vertical Deep Cone Clarifier

A key distinction of the deep cone is its height. Because of that, people sometimes refer to it as a “vertical” deep cone. These decanters build on the principle of static decantation. Static decantation involves the natural precipitation of solid material. Isolating the particle components first using these processes may reduce the volume of downstream water treatment processes like filtration.

Steps:

1. In Matec silos, the solid particles sink down to the bottom of the structure.
2. At the same time, the clean water overflows into the drainage system at the top of the silo.
3. After, this water discharges into an area for clean water.

Inside the Deep Cone Clarifier:

• The sedimentation of the solid material speeds up with the addition of polyelectrolyte (flocculant).
• Simultaneously, the cone’s design creates a column of water that presses over the sludge which creates the perfect mud thickness.
• Then, the reagents cause small particles in suspension to clump together and form larger and denser particles. The name for these particles are flocs. Flocs are quick to settle and more stable.
• This allows the separation of the solids in the clarifier to easily and efficiently occur. This process helps the conservation of energy.
• The cone’s incline perfects the thickening of mud and the upper cylinder can be used as extra storage space.
