Diatomaceous Earth (DE) worldwide has 2 sources: Salt water source, and fresh water source. Our DE is an eco-friendly naturally organic material from the purest fresh water source. Diatomaceous Earth is the fossilized remains of microscopic shells created by one-celled plants called Diatoms. Not all deposits of diatomaceous earth or the diatoms present in those deposits are the same. The shape of the diatom must be tubular with holes on the walls. It is important to have a consistent shape diatom without any unwanted sediment and it must be fresh water because the diatoms form a harder shell and is less fragile than those in salt water. Salt-water deposits contain a mix of diatom species. These deposits shapes and sediments are inconsistent, making them unusable for our products.

The source from North-East China is the only one considered as food grade and can direct using in China. Other food grade deposits may contain higher amounts of sediment and clay that make them less effective.

Since 2013, we launched different kinds of Diatomaceous Earth made product step by step, to satisfy our customer's demand.
