Abstract: The invention relates to a method for providing at least one input parameter of a sludge dewatering process of a wastewater treatment plant. The method comprises: obtaining data representing process and/or plant configuration data of said wastewater treatment plant; feeding at least part of the obtained data to at least one model formed at least by historical process and plant configuration data gathered from a plurality of wastewater treatment plants combined with properties of applied chemicals in said wastewater treatment plants; and predicting at least one input parameter and/or at least one output parameter of the sludge dewatering process by means of the at least one model for adjusting sludge dewatering process of said wastewater treatment plant. The invention relates also to a computing unit for performing at least partly the method.

Abstract: The present invention relates to a process for the production of a phosphate containing fertilizer product, comprising the steps of providing a phosphate containing precipitate from a wastewater treatment process; separating water from the precipitate to provide a dewatered slurry cake; and optionally admixing a compound selected from nitrogen, potassium and additional phosphorous containing compounds. The present invention further relates to a fertilizer and uses.

Abstract: A self-adhesive material for a wood board is described. The self-adhesive material is formed of polyolefin film having a melt index is ?4 g/10 min (measured at 190° C. and 2.16 kg), and the polyolefin film contains reactive groups with —OH groups of the wood for forming self-adhesive properties. Further, a wood board in which the self-adhesive material is used as a coating and/or as a glue-line material is described.

Abstract: The invention relates to a use of a reversible molten salt for separating hydrocarbons, such as crude bitumen and/or heavy crude oil, from material comprising mineral solids. The invention relates also to a method comprising at least the steps of: (a) bringing a liquid phase comprising a reversible molten salt, preferably a reversible ionic liquid, in a contact with mineral solids comprising hydrocarbons and extracting hydrocarbons to the liquid phase from the mineral solids; (b) separating the mineral solids phase from the liquid phase, which comprises molten salt and hydrocarbons; (c) separating hydrocarbons from the liquid phase comprising molten salt; and (d) recycling the liquid phase comprising molten salt to step (a).
