Celite 545 is a formulation of Diatomaceous Earth that is used as a filtration aid for the pre-processing of distillate. Diatomaceous earth is considered as skeletal remains of single-celled algae/diatoms formed due to sedimentary deposits. This filtration aid is used in laboratory settings and is a surface-active filtration agent which causes abrasion and the adsorption of other materials such as plant lipids. Celite 545 or Diatomaceous Earth is an effective alternative to chemical pesticides. This powder is sold in an ultra-fine powder that should be used with the proper safety equipment and should not be inhaled because it may cause respiratory damage.
