    摘要： The invention relates to a setting accelerator for a dry mortar blend, the setting accelerator being in the form of a powder comprising calcium nitrate and having a water content between 0.1% and 20%. The invention furthermore relates to a process for producing such a setting accelerator, wherein either prills and/or granules comprising calcium nitrate and a different nitrate salt are processed forming a powder comprising calcium nitrate and the different nitrate salt and having a water content of higher than 5% and lower than 20%, either an aqueous solution at least comprising dissolved calcium nitrate is spray dried at a temperature between 150°C and 250°C, forming a powder comprising at least calcium nitrate and having a water content between 0.1% and 20%, the powder serving as the setting accelerator. The invention also relates to a dry mortar blend comprising at least a cement, sand and a setting accelerator according to the invention and to a mortar paste comprising the dry mortar blend according to the invention which is mixed with water.

    摘要： The invention relates to a process for reducing the amount of sulphur compounds in a sulphur compounds contaminated wastewater stream, using a granular sludge treatment system (10) comprising anaerobic microorganisms, wherein the process comprises the steps of adding an aqueous nitrate solution to the wastewater stream, contacting the wastewater stream with the anaerobic microorganisms, and anoxic oxidation of at least part of the sulphur compounds in the sulphur compounds contaminated wastewater stream by the anaerobic microorganisms, resulting in a sulphur compounds depleted wastewater stream. The invention furthermore relates to such a granular sludge treatment system (10).
