SILICA EXTRACTION FROM GEOTHERMAL WATER

摘要

A method of producing silica from geothermal fluid containing concentration of the silica of less than 1000 ppm includes the steps of treating the geothermal fluid containing the silica by reverse osmosis treatment thereby producing a concentrated fluid containing the silica, seasoning the concentrated fluid thereby producing a slurry having precipitated colloids containing the silica, and separating the silica from the slurry.

1. A method of producing silica from geothermal fluid containing the silica, consisting of the following steps:
selecting a source of geothermal fluid containing the silica wherein said source of geothermal fluid containing the silica contains only geothermal fluid containing a concentration of silica wherein said concentration of silica is less than 1000 ppm silica, treating said geothermal fluid by reverse osmosis treatment by treating said geothermal fluid containing a concentration of silica wherein said concentration of silica is less than 1000 ppm silica by said reverse osmosis treatment thereby producing a concentrated fluid containing the silica, seasoning said concentrated fluid containing the silica thereby producing a slurry having precipitated colloids containing the silica, and separating silica in said slurry by separating silica of a size between 5-200 nm from said slurry thereby producing the silica.
