Disclosed are methods and devices that are useful for processing water-including waste such as wastewater and sludge by reacting the water-including waste with an amount of ferromagnetic powder, an amount of anionic flocculant and an amount of cationic flocculant forming ferromagnetic waste particles suspended in water of the fluid waste, the ferromagnetic waste particles subsequently separated from water of the fluid waste by application of a magnetic field.

Wastewater and sludge treatment device and method

A two stages electrocatalytic method for oxidative-purification of wastewater from soluble substances, such as toxic chemical admixtures difficult of oxidation, including dye-stuffs, detergents, phenols, cyanides and the like, which stages inactivate the soluble substances present in the wastewater in a synergistic fashion and, therefore, are highly efficient, the method comprising the steps of (a) in a first stage, electrochemically treating the wastewater in the presence of chlorine ions, such that chlorine-containing oxidizing agents are formed and at least partially oxidize the soluble substances in the wastewater; and (b) in a second stage, catalytically treating the first stage treated wastewater in presence of a non-chlorine oxidizing agent and an added catalyst, such that remainings of the soluble substances are further oxidized, and such that the chlorine-containing oxidizing agents formed during the first stage are catalytically reduced; wherein, the first stage and the second stage act synergistically to purify the wastewater from the soluble substances.
