摘要:
The present embodiments generally relate to the treatment of produced water comprising one or more water soluble polymers, wherein such treatment comprises: adding to the produced water at least one iron complex; and degrading at least a portion of the one or more water soluble polymers. This treatment may result in a reduction of the viscosity of said produced water and/or the degradation of the water soluble polymers which are contained therein.
摘要:
The present invention relates to a microbial fuel cell (MFC) unit, which comprises at least one cathode, at least one anode, which is arranged at a distance from the cathode, preferably in direction of gravity, the anode being in free contact with a surrounding medium, provided that the number of cathodes or anodes is more than one, the anode(s) and cathode(s) being connected with each other through an external electrical circuit. The fuel cell unit comprises also locating means for positioning the unit within the surrounding medium, and the fuel cell unit is free from any membranes located between the cathode(s) and the anode(s).
