I am a Senior Geologist at Qingdao Shengtai Industry Co., Ltd., where I focus on the extraction and processing of high-quality diatomaceous earth. My expertise lies in understanding the unique properties of this natural resource and how it can be applied to improve filtration, absorption, and industrial processes.

Introduction to Kieselguhr Filter Aid

Kieselguhr, also known as diatomaceous earth, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off - white powder. This powder has a high porosity, consisting of the fossilized remains of diatoms, a type of hard - shelled algae. Kieselguhr filter aid is widely used in various industries, such as food and beverage, pharmaceuticals, chemicals, and water treatment. It works by forming a porous filter cake on a filter medium, which traps suspended solids while allowing the liquid to pass through, thereby clarifying the fluid and improving its quality.
