By efficiently harnessing paddle wheel technology, the McGill Distributor provides the variable flushing intensity recognised to significantly improve the performance of trickling filters.

The common reactionary type distributor has long struggled with the fundamental link between rotation speed and flow, impeding the development of high flushing flows so beneficial to effective filter bed performance.

In breaking this link, the McGill Distributor is able to harness the natural and dynamic diurnal and wet weather flow patterns of the common combined wastewater network. This dynamic flow profile translates to a dynamic flushing intensity profile beneficial to efficient filter bed operation; minimising the thickness of biofilm, maximising active surface area and substantially increasing the biomass utilisation rate and activity throughout the media column.

MCGILL Distribution SYSTEM

The McGill Distributor has distinctive features that put clear water between it and its competitors. Most noticeable is the cantilevered inflow delivery system which stretches over the trickling filter.

By removing the under bed feed and central duckfoot arrangement, the central column is dedicated solely to structural stability, required to ensure even distribution of effluent through v-notch channels in all flow and weather conditions. Innovative flow distribution within the central console then provides further control, diverting excessive flows away from the central paddlewheels, ensuring rotation speed is controlled within a tight band.

Finally, in the absence of centrifugal force, the variable section distribution channel maximises the moment of flow reaching the outer bed to ensure an even distribution of flow across the bed.

Retrofitted by itself, or in conjunction with a wider package of system optimisation, the McGill Distributor can achieve better effluent quality without departing from the trickling filter zero energy tradition.
