ABSTRACT:
A wastewater treatment apparatus has a manifold interconnecting two or more trickle towers to enable wastewater to be sequentially moved through the trickle towers in different selective sequences. One or more sensors may sense the growth of biogrowth in the trickle towers, and when the sensed growth reaches a predetermined value, valves or other parts change the interconnection of the manifold to the trickle towers to change the sequence in which the wastewater moves through the trickle towers. A method of treating wastewater includes changing the sequence of flow through the trickle towers to achieve manual or automatic grooming of the biogrowth on the biomedia, so both improving the overall efficiency of the system and also prolonging its running time between maintenance shutdowns. Another embodiment has one or more trickle towers with suspended strands of biomedia down which the wastewater passes; a sensor senses increase in growth of biomass on at least a portion of the biomedia.
