SOLID-WALL SEPARATOR

SOLID-WALL SEPARATOR

The solid wall bowl separator is often used in processes that require liquid/liquid or liquid/solids separation when the solids content in the feed is no more than about 1% by volume. Because of the simplicity of the design, very high g force can be obtained and this separator is thus very efficient in the recovery of fine particles.

By fitting a large number of conical disks separated by spacers of between 0.3 to 2 mm, a substantially larger equivalent clarification area is achieved with the same bowl volume compared to chamber bowl separators. The equivalent clarification area is the product of the sum of the geometric surfaces of the disks multiplied with the multiple of the acceleration due to gravity.

Solid-wall separators are available in two versions:

-Separators of two liquids dissolved in one another
-Clarifiers for the separation of solids from liquids
Solid-wall separators are used almost exclusively for the separation of liquid mixtures with no or a very small solids content since the separated solids can only be removed manually.
The solid wall separator is designed to retain solids within the disc stack centrifuge and it is so called solids retaining separator.

As with disk separators with self-cleaning bowl, the disc separator with solids wall bowl is not able to periodically discharge the separated solids at full speed. Because there is no hydraulic system. So, all solids separated out by a solids wall bowl shall be removed manually.
