| description | A filter aid may include acid-washed diatomaceous earth having high purity, and perlite. A method of making a high purity filter aid may include acid washing diatomaceous earth to reduce the h in the diatomaceous earth, and combining the acid-washed diatomaceous earth with high purity perlite to obtain to obtain a high purity filter aid. A method of reducing extractable metals from diatomaceous earth may include washing the diatomaceous earth in a first acid, rinsing the diatomaceous earth, and washing the diatomaceous earth in a second acid. The first acid may include an inorganic acid having a first strength, and the second acid may include an organic acid having a second strength different than the first strength. A method of filtering a beverage may include passing the beverage through a filter including a filter aid including acid-washed diatomaceous earth having high purity, and perlite. |
