Process and apparatus for reducing the concentration of suspended solids in the clarified Brine Geothermal

摘要

The present Invention relates to a method to reduce the concentration of suspended solids in the waste stream or higher Geothermal brine effluent from a stage of CLArificaciu00f3n Primary Brine, in which a mixture of hot Geothermal Brine rich in silica,Evaporated instantly and suspended material are separated to provide a Silica or silica silu00edce Mud Flow and Geothermal Brine has a residual quantity of solids.And yet remain Suspended in the same, and with ferrous ions.The process is characterised in that it comprises: (a) current flow from the top of the Geothermal Brine clarification stage of primary Brine clarifier into a containerSecondary Flow; (b) to cover the top of the Geothermal Brine clarification stage of primary Brine Steam to prevent oxidation of ferrous ions; (c) to contacTo the current top of the Brine from the Brine clarification Stage Primary Container in the secondary clarifier with a flocculant, which comprises a aniu00f3 PolyacrylamideNicaIn such a way that at least some of the solid suspu00e9ndidos floculen; (d) unload Container Secondary clarifier Flow Fund and flocculated Solids Brine and Flow ofThe upper part; (e) combine a portion of the flocculated Solids to provide a substantially increased Solids concentration in the regions of reaction and the cloculaciu00f3n recipienYou Secondary clarifier.In which they contact the flocculating Agent and samuera Download; and (f) of the container Upper Secondary clarifier Flow clarified Brine secondarilyIn which the residual suspended Solids concentration is substantially reduced compared to the concentration of suspended solids in the waste stream from the upper partOr the Brine from the primary stage of clarification.
