Abstract

DC60 Method for separation and recovery of target components from raw liquids by membrane in Semi-batch system It consists of at least two steps of adding liquid, rinsing to it. In raw liquid to form a mixture of raw liquid and washing liquid Where by which the next step Of at least two such phases were separated by a delay Where the later steps are used Washing liquids at different concentrations, in order of decreasing order, of the target component concentration and also where at least one of these procedures uses only a washing liquid with And for each of these multiple steps, the membrane treatment process of the mixture moves the target component from Raw liquid to liquid through Method for separation and recovery of target elements from raw liquids by membrane in Semi-batt system It consists of a process of at least two parts of adding liquid, rinsing to it. In raw liquid to form a mixture of raw liquid and washing liquid Where by which the next step Of at least two of those phases were separated by a time delay. Where the later steps are used Washing liquids at different concentrations In decreasing order Of concentration, target components, and also where at least one of the many procedures uses only a washing liquid that has Concentrate near the center of the target assembly plant and for each of these multiple stages, the process of membrane treatment of the mixture is performed to move the target components from Raw liquid to liquid through

Claims (5)

1. Method for separation And the target element recovery from raw liquid by membrane In a semi-batch system, the process consists of: at least two parts of liquid addition, rinsing to the raw liquid stored in the container. And mixing of raw liquid rinsing to form mixtures of raw liquid and rinsing liquid, where the subsequent steps of at least two such phases were separated by time interval. The next step uses different concentrations of washing liquids. In decreasing order, of the target component concentration, and also where at least one of these multi-step steps use only the concentrated washing liquid. It is almost the center of the target component and for each of these many stages Execution of the procedures of meme treatments The slurry of the mixture to transfer the target component from the raw liquid to the passing liquid, whereby at least part of the incoming liquid is not used as a flushing fluid. 2. Method according to claim 1 that also includes the process of separating raw liquid into the container. Liquid coming out And residual liquid Where the discharge fluid, which is obtained by the first step membrane treatment, Of at least two steps by using a high intensity washing liquid of the target component that It has been separated from the semi-batch system. The residual liquid, which is then obtained by membrane treatment, is the final step of the sample. At least two steps by using only the liquid, the washing with a near zero concentration of the compound The target was stored in a semi-gas system and the excreted fluid was obtained by membrane treatments of at least two external stages. Above from step one and the last step are used as a washing liquid. 3. Method according to claim 1 or 2, where the target components to be separated from the liquid Raw is a valuable substance and that method also consists of the process of removing valuable substances containing liquids that are passed out of the system. 4. Method according to claim 1 or 2, where the raw liquid consists of both target components and valuable substances. The raw liquid depends on the method of producing the residual liquid with a high concentration of the valuable substance, and that method also consists of the process of removing valuable substances with residual liquid. 5. Method according to any clause Of claim 1 to 4, where the final stage of the flushing liquid Many of these processes are water.
