REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority of the Canadian application no.

2,932,009 filed on June 2, 2016. This application is thus incorporated by reference in its entirety.
FIELD OF DISCLOSURE
[0002] The present application generally refers to the dehydration of sludge, and more particularly to the conditioning of biological sludge, as well as sludge conditioning method.
INTRODUCTION

Dehydration of secondary sludge is difficult because what are consisting almost entirely of micro-organisms resulting from the treatment organic.
These microorganisms, flocculating, tend to develop a structure with a very high affinity for water retention (Randall et al., 1971., EPA, 1987).

[0004] Biological sludge is very hydrophilic, difficult flocs to dehydrate by the mechanical pressing processes generally used in this type Application and are characterized by high retention of water molecules. In the sludge side effects, mainly bacteria of a colloidal nature, varying size between 0.1 and 10 μm in diameter, hydrophilic and impermeable. They can to be deformed and have a load on their surfaces (Genco and Carbonello, 1980).

Activated sludge treatment depends on the fact that certain micro-organisms agencies are capable of forming flocs capable of decanting. Bioflocculation is caused extracellular polymers (ECPs) (Erikson and Alm, 1991). These PECs produced by bacteria in the mud form a chain in which these bacteria are incorporated (Bruus et al 1992). Bacterial polysaccharides are the main constituents of the material of these polymers but these contain also proteins and nucleic acids (Sanin and Vesilind, 1994).

Faced with the difficulty of dewatering sewage sludge and problems related to the use of the usual sludge digestion processes, various chemical processes combined thermal and sewage sludge conditioning have been developed at during the last years. However, most of these processes remain too much expensive to be widely used in wastewater treatment plants municipal and industrial.

[0007] Various electrochemical processes are proposed for the decontamination and the conditioning of biological sludge (of municipal and Industrial). For example, Canadian patent document CA 2,382,357 describes a process using landfill electric (pulsed electric fields) under high voltages (15 000 to 100 000V) affecting bacterial cells causing disturbances physiological and thus causing a release of the inter and intra cellular liquid, which reduces up to about 50% (w / w) the mass of sludge generated after dehydration mechanical sludge. The best yields of this system (pulsed electric fields) are obtained by imposing high energies of about 100 J / mL or 400 kWh / tbs for initial sludge with a total solids concentration of 6%. said method of treatment of sludge from the Canadian application CA 2,382,357 can to permit improve sludge dryness but remain ineffective for disposal odors foul.

Canadian patent CA 2,511,091 describes an electrochemical process of conditioning and stabilization of municipal sewage sludge and industrial. said process involves the steps of acidification, followed by electrolysis in a cell comprising electrodes and whose anode is capable of generating in situ a oxidant bactericidal and this, in order to generate electrolyzed sludge with a dehydrability and greater stability than sewage sludge.

Canadian patent CA 1,334,658 describes an electrolytic cell for the treatment of sewage sludge, which is equipped with a multitude of flat electrodes placed in parallel (anodes and cathodes) and individually connected to the generator of current capable of delivering a voltage varying between 1.5 and 20 V.
iron electrodes (anode) and stainless steel (cathode) are arranged so that a anode be immediately followed by a cathode with an inter-electrode distance relatively weak (15 mm). This process can induce the transformation of substances particulate hydrophilic (organic and inorganic) hydrophobic substances, which can to improve the filterability of biosolids during filtration mechanical.

The methods developed in CA Canadian patent documents 2,382,357 and CA 1,334,658 do not mention the presence of an oxidant bactericidal the action could extend into the sludge at the outlet of the electrolyser (residual effect).
The residual effect of the oxidant would provide stability to more or less long term treated and dewatered sludge. Indeed, in most stations purification, Dehydrated sludge is initially stacked and stored at room temperature ambient before any final disposal (landfilling, spreading or incineration). In particular, in the method of Canadian patent document CA 2,382,357, even if the cell bacteria were physiologically disturbed by application of a field electric pulsed, they are however able to reactivate when they are find in a more favorable environment (in the absence, in particular, of a disruptive effect:
field electric). A bacterial reviviscence could thus be observed during the period of sludge storage and, as a result, lead to odor nuisances induced by organic and inorganic malodorous compounds.

agitating the sludge by rotating said at least one moving electrode, said mud fluid being treated and conveyed between said electrodes which are arranged in a chicane and in a manner substantially perpendicular to the meaning of displacement overall sludge conveyed between an inlet and an outlet in a device.
Said method can make it possible to increase the dryness of the mud.

In another aspect, the disclosure relates to an apparatus for electrical conditioning of biological sludge. The device has an entrance and output; a body intended to receive the sludge to be treated and defining an axis of rotation;
an entry and an output that are in fluid flow communication with each other and with said body; at least one internal electrode and at least one external electrode allowing treat said mud and disposed within said body, said electrodes being arranged in a way substantially parallel to each other, at least one of said electrodes being movable and adapted to rotate about said axis of rotation, said electrodes defining between them at least one space intended to receive the mud to be treated;
