Abstract: A tank has an inlet opening mounted at an end wall at the beginning of an elongated horizontal path for supplying a mixture to be separated, and two outlet openings mounted at the end of the elongated horizontal path for separately draining the separated liquids. An outlet opening located below the inlet opening and is connected to a vertical channel furnished with a sink located at least on the level of the inlet opening.

Abstract: The present invention provides a new and improved method and apparatus for separating a disperse mixture of two non-miscible liquids to increase the separation extent within less time required as per usual. The proposed method includes the steps of providing a tank having an elongated horizontal extension terminated by two end faces (4, 5), creating within said tank an interface (13) between a first layer formed by a volume of one of said two liquids and a second layer formed by a volume of the other of said two liquids with, and supplying said disperse mixture into the tank from one of said end faces (4) thereof directly into said interface (13).

Abstract: There is provided a method for producing granular fertilisers that includes at least one structural compound based on at least two salts. The method includes the steps of disposing of at least one salt that includes nitrogen, humidifying the at least one salt, mixing the at least one humidified salt with at least one substance comprising at least one alkaline and/or alkaline-earth element and/or at least one element of group IV, producing a granular fertiliser by granulation of the mixture, and cooling the granular fertiliser. There is also provided a granular fertiliser comprising nitrogen and having a pH in the range of 3?pH?7. The granular fertiliser shows a strength ? of ??3 MPa and includes a concentration cSC of at least one structural compound with cSC?50 wt.-%.
