TecnoConverting Engineering replaces three longitudinal rail bridges with high-strength rectangular scrapers at Sant Feliu de Llobregat WWTP.
TecnoConverting Engineering performs all the structural calculations for the sizing of the drive shafts, drag blades, and traction chains. This allowed us to design stronger scrapers by adding a central chain to ensure greater rigidity of the blades with that width. It is noteworthy that the equipment comes equipped with 2 safety systems: the parallelism detector, which stops the equipment if the blades are working misaligned, and the electronic torque limiter, which stops the equipment if any element gets trapped in the collection system.
With the newly installed Strongest scrapers, which have collecting blades every 3 meters, the collection of sludge and floatables becomes much more efficient. Solids are continuously deposited in the collection wells and floatables in the upper skimmer. As a result, the daily purges need to be increased due to the increased settled sludge during the same period of time.
Another advantage is the possibility of installing lamellar modules in the future, potentially increasing the capacity of the existing primary settlers up to 4 times.
