Abstract:
A flow-through electrochemical reactor for the treatment of wastewater from a debarking process the wastewater being forced through the reactor to lower organic compounds present in the wastewater to an environmentally acceptable level comprising:a body having an internal chamber, and an inlet port and an outlet port in communication with said internal chamber, said inlet port and outlet port in sealing engagement with the internal chamber and adapted for sealed connection to an open recirculating system; a series of sponge type metallic electrodes arranged in said internal chamber such that the wastewater flowing between said inlet port and said outlet port flows through openings of said sponge type metallic electrodes, at least one of said sponge type metallic electrodes having activity for the destruction of a target substance such as phenol and cresols; said series of sponge type metallic electrodes having sufficient mechanical strength to withstand a flow of 60 liters/min, the series of electrodes comprising and alternating arrangement of cathodes and anodes there being at least three cathodes and two anodes the cathodes being negatively charged and the anodes being positively charged.
