摘要： The invention relates to a method and a system for controlling a membrane separation unit of an aqueous liquid effluent treatment plant comprising a system for injecting at least one chemical compound into the effluent to be treated. The method and the system allow regulating at least one parameter selected from an amount of chemical compound(s) to be added and a conversion rate in order to avoid clogging and/or precipitation of ionic species in the retentate. This regulation uses optimum setpoint values determined according to one or more parameter(s) characteristic of the retentate and not of the water to be treated. Thus, an accurate regulation of the amount of chemical compound(s) to be added and/or of the conversion rate of the membrane separation unit at an optimum value allowing at the same time avoiding clogging and/or precipitation of the species likely to precipitate and minimising the operating costs is achieved.

摘要： Cations that can precipitate from an aqueous composition to produce scaling are sequestered by adding a multi-dentate ligand to the aqueous composition. The multi-dentate ligand bonds with the cation to form a non-scaling ionic complex; and the aqueous solution with the ionic complex is used in a process that produces substantially pure water from the aqueous composition, where the cation, absent formation of the ionic complex, is subject to scaling. The pH of the aqueous composition (or a brine including components of the aqueous composition) is then reduced to release the cation from the multi-dentate ligand; and the multi-dentate ligand, after the cation is released, is then reused in a predominantly closed loop.

摘要： The present invention generally provides a process for treating a soapstock. The present invention more particularly provides systems and methods for treating a soapstock to generate free fatty acids and/or fatty acid derivatives, e.g. fatty acid alkyl esters. The present invention more particularly provides systems and methods for realizing the full fatty acid yield of a soapstock by first converting substantially all of the saponifiable material in a soapstock to salts of fatty acids (soaps) and acidulating the soaps to generate free fatty acids and/or fatty acid derivatives, e.g. fatty acid alkyl esters, wherein the soapstock comprises soaps and saponifiable lipids, e.g. glycerides and/or phospholipids, and the generating of free fatty acids and/or fatty acid is achieved without the use of a mineral acid.

摘要： A method of chemical extraction from an aqueous solution includes receiving an aqueous solution including dissolved inorganic carbon. The method also includes increasing a pH of a first portion of the aqueous solution to form a basic solution. The basic solution is then combined with a second portion of the aqueous solution to precipitate calcium salts. The calcium salts are then collected.
