Abstract: Electrochemical device for producing biocide solutions A device for producing biocidal solutions comprising a flow through undivided electrochemical cell for electrochemically activating an electrolyte to produce an electrochemically activated solution which is biocidal, the electrochemical cell having an anode and a cathode, wherein the separation between the anode and the cathode is less than 3.0 mm and the electrochemical cell having a capacity to hold no more than 20 ml of electrolyte within the electrochemical cell.

Abstract: There is provided an automated electrochemical device for generating a biocidal output solution, said device comprising: a flow-through electrochemical cell comprising an anodic chamber and a cathodic chamber for electrolysing an electrolyte to generate an anolyte solution and a catholyte solution; characterised in that the device further comprises: (i) a reservoir for storing catholyte; and (ii) a hydraulic circuit for recirculating catholyte from the reservoir to the anolyte on start-up of the cell, wherein input of catholyte of a compensating strength to the cell anodic chamber, is arranged so as to optimise the cell anolyte pH to produce a stable output solution at the start of the electrolysis process.

Abstract: The present invention provides an apparatus and method for biologically treating fluids, in particular municipal or industrial wastewater or the like, the apparatus comprising a pair of reservoirs each containing growth medium having a biofilm thereon, the apparatus being arranged to pump the wastewater from one reservoir to another such as to alternatively expose the biofilms within the reservoirs to air and wastewater, thus making it possible to achieve sequential aerobic, anoxic and anaerobic conditions in the biofilms.
