Retrievable Grid Designs: A Key Strength of the OTT Group

Since 1992, the OTT Group has achieved industry-wide recognition as a supplier of retrievable grids for round basins, rectangular basins, cascade aerators, lagoons, SBR tanks and many other WWTP configurations. Our field-proven solutions reliably lift and lower grids without disrupting the treatment process.

Our components and systems have proven their worth in hundreds of projects worldwide. Design engineers and plant operators alike profit from our standardized solutions which can be integrated or retrofitted in almost any aeration basin.
