  • Patent number: 11772985
    Abstract: A computer implemented method and a system abates the presence of sulphide (H2S(g), H2S(aq) or HS-(aq)) in a wastewater flowing in a specific wastewater network from an upstream pumping pit to a downstream pumping pit or manhole. The computer implemented method and a system includes dosing into the wastewater at a position upstream of the downstream pit or manhole a chemical for abatement of sulphide, determining by use of a sensor the concentration of sulphide at a position downstream of the position at which chemical is dosed into the wastewater, such as located in the downstream manhole. The amount of chemical dosed is determined by use of a general agent and a specific agent.

  • Publication number: 20080034669
    Abstract: A coated super-hard abrasive comprises a core of super-hard abrasive material, which is typically diamond or cBN based, an inner layer of a metal carbide, nitride, boride, boronitride or carbonitride chemically bonded to an outer surface of the super-hard abrasive material and one or more outer layers of a metal carbide, nitride, boride or carbonitride physically deposited on the inner layer. In the case of a single outer layer, the single outer layer has a composition gradient extending through its thickness, and in the case of more than one outer layer, the composition of each layer is different to provide a gradient of material through the various layers. In the case of several outer layers, each layer may also include a composition gradient.
