摘要： Method of recovering iron and/or phosphorus from sludge of waste water treatment plants, said sludge being obtained after precipitation by iron salts, wherein said method comprises separating sludge from waste water and submitting said sludge to a lactic fermentation to release a liquid phase where iron and phosphorus are dissolved. Lactic fermentation is performed with addition of a co-substrate rich in carbon, preferably rich in carbohydrate, in one single step of biological acidification or a sequencing biological acidification in two steps by first releasing phosphorus from the PAO contained in the sludge. Iron can then be recovered by means of a cationic exchange resin. Phosphorus can be recovered as struvite or calcium phosphate from the remaining solution substantially free from iron ions, after a precipitation step in presence of a magnesium or calcium source and a pH above 7.

摘要： A method for controlling the activity of an electrochemical device (11) comprising a bioanode (3) and a biocathode (6) immersed in an electrolyte (10A, 10C) containing microorganisms, the anode compartment (8) and cathode compartment (9) being separated by at least one membrane (14), optionally a reference electrode, a difference in potential being applied between the bioanode (3) and the biocathode (6), or between the bioanode and the reference electrode, characterised in that the operation of the device is governed by a dual control: —a priority control of the difference in potential between the bioanode and the biocathode, or between the bioanode and the reference electrode, between a minimum limit value allowing the development of an electroactive biofilm at the bioanode and a maximum limit value lower than the oxidation potential of said biofilm, and—a secondary control, when the first control is in place, optimising the Faradaic efficiency of the biocathode. A device allowing said method to be carried out.

摘要： A method for the real-time estimation of the total consumption of a fluid, in particular water or gas, distributed from a unit (A) to users (b1, b2 . . . ) via a network of supply pipes (E) with a branch (d1, d2 . . . ), for each user, fitted with a counter (c1, c2 . . . ) of the fluid consumed by the user, which method involves defining cohorts of users having homogeneous behavior with regard to the consumption of fluid; defining, for at least one of these cohorts, a sample of users from the cohort that is statistically sufficient to represent the cohort; fitting only the branches of the users of each sample with a remote reading device (t1, t2, . . . ) for reading the consumption; also fitting remote reading devices to the branches of the users of the other cohorts that have not been sampled; and processing the information provided by the remote reading devices to obtain a real-time value representative of the total consumption of the network.
