Sand grains are washed to remove any unwanted silt and clay particles. Wash water is then pumped to a nearby settling tank where flocculants (polyacrylamides) are added to remove suspended particles. These particles, along with sand thats too fine for hydraulic fracturing, make up about 2030% of the total weight of the raw sandstone.
