Exercise: Nemo in Action
Scenario: A wastewater treatment plant is experiencing frequent clogging in its pipelines due to large solids present in the wastewater.
Task: Explain how Netzsch Nemo PCPs and macerators can be used to address this problem and improve the overall efficiency of the wastewater treatment plant.
Exercice Correction
Netzsch Nemo PCPs can be used to pump the wastewater effectively even with the presence of large solids. However, to prevent clogging in the pipelines, a Netzsch Nemo macerator can be installed upstream. The macerator will break down the large solids into smaller particles, making it easier for the PCPs to pump them and reducing the risk of clogging. This combined solution will improve the overall efficiency of the wastewater treatment plant by reducing downtime caused by clogging, increasing the flow rate of wastewater, and ultimately contributing to a more sustainable and efficient treatment process.
