Definitions

  • the invention relates to a water purification method, as well as a water purification plant in which this method is implemented.
  • the method according to the invention is a purely mechanical process because of which no chemicals or electricity is needed. This is particularly of advantage when the method is implemented at locations where no or insufficient electricity is available and/or no or insufficient chemicals are available.
  • An advantageous embodiment of the method according to the invention is characterized in that, prior to the processes described above, first the water to be treated undergoes an adapted pre-treatment in which the primary constituent of pollution is removed from the water by means of one or more of the following processes: prefiltering, membrane filtering, micro-filtering, chemical flocculation, treatment with an eddy current separator.
  • Mineralization of drinking water is preferably effected by means of calcium carbonate injection or by passing the water through a marble filter.
  • the invention likewise relates to a water purification plant.
  • the invention is characterized in that it comprises the following series-connected devices:
  • an activated carbon treatment device and a reverse osmosis device where the latter two devices may also be incorporated in the plant in a different order
  • An embodiment of the water purification plant according to the invention is characterized in that the water purification plant comprises a pre-treatment system in which the primary constituent of pollution is removed from the water, which pre- treatment system comprises one or more of the following devices: prefiltering device, membrane filtering device, micro-filtering device, chemical flocculation device, eddy current separator.

  • Fig. 1 gives a diagrammatic representation of an embodiment of the method according to the invention.
  • the polluted water Prior to the start of the intensive purification, the polluted water is first subjected to a pre-treatment 1, in which the primary constituent of the pollution is removed from the water.
  • This pre-treatment is embodied by one or more of the following processes: prefiltering, membrane filtering, microfiltering, chemical flocculation, and eddy current separator treatment.
  • ultrafiltering 3 utilizing filters that have a pore size of approximately 250 nm, by which all visible impurities such as, for example, viruses, bacteria, worms, sand and floating particles are filtered from the water,
  • UV light treatment 5 by which biological impurities are removed from the water, micro- aeration 7 in a vessel, in which by means of oxidation for example scent, colour, taste and metals are removed from the polluted water,
  • Microfiltering, ultrafiltering and nanofiltering that is, reverse osmosis, are comparable methods, they only differ in sizes of the filter openings.
  • the molecules that are stopped by means of ultrafiltering are smaller than they are in the case of microfiltering. So both ultrafiltering and microfiltering are used for removing macromolecules from a solution. Molecules having a weight of less than 1000 g/mol and ions are hardly stopped by ultrafiltering. When nanofiltering is applied even smaller molecules of up to 200 g/mol can be stopped, as well as polyvalent ions.
  • Reverse osmosis is a process based on diffusion in which a difference in pressure is realised over a semi-permeable membrane, as a result of which this membrane starts working as a filter: the solvent will start to move to the side where the sum of the external pressure and the osmotic pressure is lowest.
  • the pure solvent without carrying along the dissolved materials
  • water is pushed very hard through a sieve that has microscopically small openings.
  • UV light breaks off organic refuse matter and renders organic micro pollutions harmless. No harmful residual material is left in the water then.
  • Activated carbon is a specially treated carbon that has the feature of being able to bind all sorts of materials to it.
  • Activated carbon is a strong adsorption agent.
  • the effect of activated carbon is based on a very large surface by a fine micro structure with a large number of very fine pores.
  • Commercially available types of activated carbon have an internal surface from 500 to 2000 m 2 /g.
  • the activated carbon particles (carbon atoms) exert attraction on gaseous or fluid particles (molecules) that surround or flow through the activated carbon.
  • the degree of attractive power is determined by a plurality of factors, for example, by the shape and size (weight) of the molecules that come into contact with the activated carbon. Just because not all molecules are equally strongly attracted and retained (adsorbed) by activated carbon, it is posisble to remove one or more undesired materials from the water.

Abstract

L'invention porte sur un procédé de purification d'eau ainsi que sur une usine de purification d'eau. Dans un procédé au moyen duquel sensiblement n'importe quelle forme d'eau polluée peut être purifiée et transformée en eau potable, l'eau à purifier est soumise successivement aux traitements suivants : ultrafiltration, traitement aux rayons ultraviolets, micro-aération, traitement par du charbon actif et osmose inverse, l'ordre des deux dernières étapes étant interchangeable, traitement prolongé aux rayons ultraviolets, minéralisation et micro-aération prolongée. Il s'est avéré que soumettre deux fois l'eau à un traitement aux rayons ultraviolets conduit à un degré très élevé de purification d'eau. Après que l'eau a été soumise aux six premiers traitements parmi les traitements ci-dessus, elle devient trop pure à boire. Il en résulte qu'une minéralisation de l'eau est nécessaire pour la rendre potable. Pour neutraliser l'odeur, la couleur et le goût que l'eau peut avoir obtenu après minéralisation, l'eau est ensuite soumise une fois de plus à un traitement de micro-aération.
