Definitions

  • ABSTRACT This invention is directed to the disinfection of liquids, especially water-containing liquids. It has been found that by the simultaneous use of anodic oxidation and silver ions a synergistic disinfection effect is achieved.
  • the invention provides a method for disinfecting liquids. especially water-containing,liquids, in which the liquid to be disinfected is subjectedto the effect of an electric current in an electrolytic cellcomprising an anode and a cathode, the anode being made of silver or a silver-containing. material, the. disinfection, taking place substantially in the electrolytic. cell.
  • the amount of silver ions entering into the liquid can be smaller than the amount which is necessary, if one merely relies on silver ions for the disinfection. So if is possible to work with very small amounts of silver.
  • F is the anode surface in cm and V is the flow rate in cm per sec and k is a constant having the value 5/3 sec/cm and implying the distance between the anode and the diaphragm and the reaction time.
  • the relationship between the electrode surface and the electrolytic cell must be such that the contaminations and poisons resp. are reduced to a desired value within the cell. It is frequently necessary to adapt the surface of the electrode to the specific contaminations and/or poisons. This relationship can be found by someone skilled in the art by simple experiments, when considering that a certain minimum of concentration of the contaminations or poisons must be achieved on the one hand and the investment for the apparatus should be kept at a minimum at the other hand.
  • the reference number 1 denotes the container of the electrolytic cell
  • 2 is the anode and 4 the-cathode.
  • cathode compartment of the cell 7 the anode compartment und 8 the diaphragm dividing the space in container 1 into said two compartments.
  • 9 denotes the water inlet and 10 the outlet for withdrawing purified water.
  • the method of operation of the apparatus is as follows: i
  • the oxidizing effect i.e. the abstraction of electrons, is very effective, for also normally badly oxydizing substances are affected. This is also true for the microorganisms within the water which, since being organic compounds, are decomposed by oxidation and, accordingly, are destroyed.
  • an asbestos sheet can be used, but particularly advantageous results have been obtained with a material only permeable to anions, since in this case a concentration of anions in the anode compartment 7 takes place.
  • the cathode compartment 6 is suitable provided with a deaerationor passage possibility so as to be able to evacuate hydrogen occurring in very small quantities.
  • inlet means for admitting said contaminated water to said anode compartment
