Claim:
A wastewater treatment system comprising: an influent splitter configured to receive an influent having a concentration of a pollutant that exceeds the permitted discharge standard for the pollutant and to deliver a first fraction of the influent to a first inlet and deliver a second fraction of the influent to a second inlet; a first wastewater processor in fluid communication with the first inlet and including a first outlet and a membrane bioreactor in a first wastewater path from the first inlet to the first outlet, the first wastewater processor being configured to produce a first effluent having a concentration of the pollutant less than the permitted discharge standard; a second wastewater processor in fluid communication with the second inlet and including a second outlet and a biological wastewater treatment system in a second wastewater path from the second inlet to the second outlet, the second wastewater processor being configured to produce a second effluent having a concentration of the pollutant greater than the permitted discharge standard; and an effluent path configured to receive at least a portion of the first effluent and at least a portion of the second effluent and deliver a blended effluent having a concentration of the pollutant no greater than the permitted discharge standard.
