Description

The GPB OS2 pilot allows to characterize a reverse osmosis module and to study the different parameters that determine the quality of the water obtained. The practical realization is made using softened raw water and a saline solution and it is proposed to determine: The osmotic pressure for the solution studied and the overall apparent retention of the reverse osmosis module. This study allows users to become aware of the conditions of reverse osmosis operations in industrial production. The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on wheels gives it a very high robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machine Directive.

The bench includes a power supply box that complies with European electrical standards with a standby power disconnector, white voltage presence light, emergency stop button, earthing connection and differential protection.

1. Mains water supply circuit including 10μm cartridge filter and activated carbon filter
2. 80L feed tank with the following elements:
drain valve
Low level sensor (minimum level)
3. Vertical multi-stage diaphragm feed pump in stainless steel. Maximum pressure: 16 bar.
