through the nozzles should also be given due consideration while designing.
This outflow velocity through nozzles can be kept between 0.5 and 4.0 m/s. The equation of ’condition for maximum power transfer through nozzle’ can be used for working out nozzle or inlet pipes diameter. The clogging of the nozzles may represent serious problem resulting in uneven distribution of the wastewater over reactor bottom, particularly when treating partially soluble wastewater. Hence, arrangements should be made for cleaning or flushing the inlet system.
