Description

The GPB OS1 bench can show students the characteristics of a reverse osmosis unit and study the different parameters, determine the quality of the water.
The practical implementation is carried out using a softened raw water and a saline solution and it is proposed to determine:
The osmotic pressure for the studied solution
This study allows students to become aware of the conditions of reverse osmosis operations in industrial production.
The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises.
The manufacture of this equipment complies with the European standard for machinery manufacturing.
