Abstract:
A biofiltering device for treating wastewater, comprising:a housing having inlet means for receiving the wastewater to be treated and outlet means for discharging the treated wastewater; a bed of peat disposed inside said housing between said inlet and outlet means, said peat defining a biofiltering medium having a predetermined biofiltering capacity; means for aerating said peat; and a fluid flow control system arranged over said bed of peat and in fluid flow communication with said inlet means, and adapted for distributing the wastewater through said bed of peat in a manner such that when the wastewater enters said system at a flow rate greater than the biofiltering capacity of said peat, the wastewater discharged from said system flows through said bed of peat at a flow rate no greater than said biofiltering capacity.
