Decantation unit (sedimentation)

DESCRIPTION

The purpose of this unit is to separate solid particles suspended in a liquid by allowing them to settle under their own weight.

The unit allows for the study of hydraulic characteristics to be considered when using a decantation tank on a small scale.

Continuous process.

This system is easy to use.

This unit is designed for various levels and fields of study.

Technical documentation and instructions are provided.
