Abstract: Methods are described for treating aqueous solutions, including wastewater, to remove nitrogen-containing compounds using electrochemical processes. The method may be conducted electrolytically under an applied voltage or using endogenous current in a fuel cell arrangement. In some embodiments, energy is reclaimed in the form of hydrogen, methane, and other hydrocarbons or organic molecules. Microorganisms may be used as the catalyst for oxidation of the nitrogen-containing compound and/or reduction of hydrogen ions, carbon dioxide, or bicarbonate. Anaerobic or low-oxygen conditions may be used in the zone.

Abstract: A kit-of-parts for attaching an object on a substrate (1, 1?) having (i) at least a first solution having at least one first compound, wherein the first compound is at least one of a gelling agent, a gellable agent, and a thickening agent, and (ii) at least a first substrate (1, 1?) having a surface (2, 2?). The first solution is suitable for forming at least a first dispersion of an object in the first solution when a the object is added to the first solution. The first dispersion is suitable for attaching the object on a functionalized surface (3, 3?) of the substrate (1, 1?) when the first dispersion is added to the functionalized surface (3, 3?) of the substrate (1, 1?).

Abstract: The invented bio-electrical system is a housing-electrode which allows insertion of another electrode for various electrochemical and bio-electrical applications. Together with other invented elements as well as standard components, the system is fully scalable, modular, and allows production and collection of gases under pressure. It can be built in many shapes, such as the embodied tubular shape. The design allows operation on unstable ground, for example on ships. Flow of electrolyte can be regulated and directed in cascaded reactions by opening and closing the compartments of the outer or the inner electrodes using the provided electrode holders. The redox conditions inside the system can be controlled using off-the-shelf power supplies which are controlled using the provided algorithm. Gas collection can be regulated based on the level of liquid inside the system using the provided float switches or conductivity probes even as the system is moving or operated under zero-gravity conditions.

Abstract: In the manufacture of cement clinker from cement raw meal, sulfide-containing raw materials or raw materials with a high TOC (total organic carbon) level can be used for cement manufacture, which are uncontrollably incompletely burned in the upper cyclone of a heat exchange line, thus leading to high emissions of CO, VOC (volatile organic carbon), and S2− in the waste gas. To reduce or completely eliminate such elevated emissions, an oxidation zone is provided in an waste gas duct downstream of the heat exchange line in the gas flow path, having an afterburner, the waste gas being caused positively to pass through open flames of the afterburner to assure the economical oxidation of the waste gas.
