The present invention relates to a device and a method for recovering a large and dry precipitated solid inorganic final product (3D), consisting of phosphorus, nitrogen and an element X selected from the alkaline-earth metals, from a first fluid (1) consisting of at least one divalent cation X2+ mixed with a second fluid (2) containing phosphorus and nitrogen, said device including at least one first reactor (19) which is intended for a primary crystallization reaction, has any shape, and is connected to a second spiral-shaped reactor (20) for secondary crystallization/deposition.

Process for making solid methylglycine diacetate (MGDA) alkali metal salt (a), said process comprising the steps of (A) providing a 35 to 60% by weight aqueous solution of said MGDA salt having a temperature in the range of from 50 to 90 C., (B) adding 0.01 to 2% by weight of a particulate solid with a pore volume in the range of from 0.25 to 0.75 cm.sup.3/g, determined by nitrogen adsorption in accordance with 66134:1998-02 (b), the percentage referring to the content of (a), (C) crystallizing (a), (D) removing said crystalline (a) from the mother liquor.

A method includes supplying a supersaturated brine stream having a plurality of minerals and anti-scalant from a water treatment system to a gypsum removal system disposed within a mineral removal system. The gypsum removal system includes a gypsum reactor that may receive the supersaturated brine, may deactivate the anti-scalant such that gypsum precipitates from the supersaturated brine, and may generate a gypsum slurry having a mixture of desupersaturated brine, precipitated gypsum, and the anti-scalant in solution with the desupersaturated brine. The method also includes supplying gypsum seed crystals to the gypsum reactor. The gypsum seed crystals may precipitate the gypsum from the supersaturated brine to generate the gypsum slurry. The method also includes directing a first portion of the gypsum slurry from the gypsum reactor to a gypsum settler. The gypsum settler may reactivate the anti-scalant such that the anti-scalant absorbs onto the precipitated gypsum to remove the anti-scalant from the desupersaturated brine and may generate anti-scalant-gypsum crystals and a desupersaturated overflow having at least a portion of the plurality of minerals. The method further includes generating the gypsum seed crystals supplied to the gypsum reactor using the anti-scalant-gypsum crystals.

The invention relates to a method for increasing the purity of oligosilanes and/or oligosilane compounds, in which a first liquid substance mixture formed from at least 50% oligosilane compounds comprising inorganic oligosilanes and/or halogenated oligosilanes and/or organically substituted oligosilanes is provided, and the first liquid substance mixture is subjected to at least one purification sequence, wherein in a first step a) the liquid substance mixture is temperature adjusted to a temperature at which at least one fraction of the oligosilane compounds solidify, and in a second step b) at least one fraction of the liquid substance mixture is separated.
