摘要： Disclosed herein are a treatment method and a treatment system which are capable of inexpensively, efficiently, and safely treating wastewater discharged from a gasification plant in large amounts and containing two or more persistent substances. The method for treating wastewater discharged by wet-cleaning of gas obtained by partial oxidation of fossil fuel includes: a free cyanide removal step 2 in which free cyanides contained in the wastewater are removed by acidifying and aerating the wastewater; a biological treatment step 3 in which the wastewater that has been treated in the free cyanide removal step 2 is biologically treated; and a decomposition treatment step 4 in which COD components contained in the wastewater that has been treated in the biological treatment step 3 are decomposed. The decomposition treatment step 4 is preferably performed by an advanced oxidation treatment means, and may include the step of crystallizing calcium sulfate by adding a calcium-based alkaline agent to the wastewater.

摘要： A filtration system suitable for recovering base stock from used lubricating oil and other applications pass feedstock over nano-filtration membranes assembled as a stack of membranes all experiencing parallel flow. On exiting a first stack of membranes the feedstock passes through an opening in a pressure-sustaining separator plate to flow in the reverse direction past a second stack of membranes and subsequently establish a serpentine flow of feedstock through multiple stacks of membranes. The stacks of membranes all share a common pressure containment vessel. Pressure boosters installed in the flow-through openings of separator plates separating consecutive stacks can serve to restore lost pressure of the feedstock and maintain effective permeation of permeate through the membranes. A pressure control valve at the outlet to the permeate-receiving cavities of a stack can be used to adjust the trans-membrane pressure.
