Abstract:
РЕФЕРАТ Сорбционный аппарат содержит корпус, эрлифт, циркулятор, диспергатор, патрубки для ввода и вывода пульпы или раствора, а также сорбента, дренаж, расположенный ниже уровня пульпы. При этом дренаж выполнен в виде погружного 5 дренажного устройства с сужающимся днищем и с дренажной трубой, обеспечивающей вывод из аппарата самотеком пульпы или раствора, диспергатор выполнен в виде перфорированной трубы, на внешней поверхности которой размещены эластичные элементы, расположен внутри циркулятора и соединен с патрубком для подачи сжатого воздуха. Предложенная конструкция сорбционного аппарата позволяет при проведении 10 непрерывного процесса сорбции из раствора или пульпы повысить надежность работы аппарата, упростить его обслуживание, сократить эксплуатационные затраты за счет сокращения потерь дорогостоящего сорбента.

Abstract:
The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from minerals, and recycled products.
Abstract:
A system is provided for removal of undesirable dissolved substances from solutions containing two or more dissolved substances to produce one or more new solutions suitable for beneficial use. The system utilizes amphoteric media in a treatment cycle where dissolved substances from the concentrated solution are first adsorbed by the media and subsequently rinsed with water to desorb and collect the dissolved substances sequentially into dilute effluent streams the substances are either aggregated or segregated based upon differences in relative concentrations of dissolved substances that is a result of differences in the affinity of the media for the dissolved substances. One or more of the dilute effluent streams are treated with a desalination process to recover water for media rinse and to concentrate the separated dissolved substances to facilitate beneficial use or disposal. The system provides economical and environmentally superior treatment of marginal quality water for beneficial use without the requirement for large quantities of treatment chemicals and waste sludge typical of precipitation processes used for removal of undesirable dissolved substances.
