Description

The GPBT70 trainer allows the study of an activated carbon filter and a chlorination loop with a dosing pump.

The raw water is contained in the feed tank, a centrifugal pump will send it to the filtration column containing the activated carbon. It can then pass through a UV sterilizer (GPBT71 option) and then be collected in the treated water tank. A metering pump supplies the pipeline with chlorine. It operates manually and can be regulated (GPBT73 option) by a regulator with free Cl2 probe and pH probe. Students will also be able to take samples and analyze the amount of chlorine in the water using the optional portable device (reference GPBT72).
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.
