Automatic dispenser HydroDoc™

trickling filter

The HydroDoc™ Trickling Filter Rotary Distributor is the most efficient and best operating rotary distributor available anywhere. Trickling Filters can be a reliable part of the efficient operations of wastewater treatment plants. The HydoDoc™ is completely hydraulically driven, just like our Standard Rotary Distributor. The HydroDoc™ has automatically adjusting gates which are pneumatically controlled to open and close the orifices in equal proportion on both sides of the distributor arms. A sensor on the center assembly transmits speed readings to the control box, which automatically adjusts the speed to match the preset operational or flushing program. As flow to the trickling filter varies, the speed is maintained by automatically adjusting the gates over the orifices. By regulating the dosing through the filter media, the biomass becomes healthy throughout the depth of the trickling filter. A daily flushing cycle cleans the media and flushes dead biomass, leaving an optimally active film on the media. Healthy media results in optimal treatment process.
