Abstract (en)
[origin: WO2015082548A1] The invention relates to the use of a gel, consisting of a colloidal solution including, preferably consisting of: 5 wt % to 30 wt %, preferably 5 wt % to 25 wt %, preferably still 8 wt % to 20 wt % relative to the weight of the gel, of at least one inorganic thickening agent; a mineral base selected among the alkaline metal hydroxides, the alkaline-earth metal hydroxides, and the mixtures thereof, said mineral base being present in an amount of 0.05 to 10 mol/L of gel, preferably in an amount of 0.1 to 5 mol/L of gel; a stable oxidising agent in a basic medium selected among the permanganates, the persulfates, ozone, the hypochlorites, and the mixtures thereof, said stable oxidising agent in a basic medium being present in an amount of 0.05 to 5 mol/L of gel, preferably 0.1 to 2 mol/L of gel; 0.1 wt % to 2 wt % relative to the weight of the gel of at least one surfactant; and a solvent; the gel not containing a superabsorbent polymer; in order to remove a biofilm located on a surface of a solid substrate.
