Last week, we intervened at a wastewater treatment plant located in the south of Nantes to install a compacting unit bar screen on a pumping station.
Due to the particularity of this position (elevated above the natural terrain, with a large depth) and the positioning of the bar screen (dislocated inlet pipe for the effluent), we had to carry out meticulous measurements before starting the manufacturing process. The adaptability bar screens of our civil engineers is particularly relevant in this installation.
On the day of the installation, we carried out the following operation:
– Assembly of the lower chassis (in two parts) on the ground
– Handling of the lower chassis (7500mm high) and installation in the post
– Leveling and fixing of the lower chassis
– Handling and installation of the upper chassis, bolted to the lower chassis
– Handling, positioning and fixing the compaction screw
– Installation of the electrical box and its support on the post, near the bar screen
– Electrical connections, adjustments and testing
– Training of operating personnel.
The duration of our intervention was limited to one and a half days.
