Sichuan Honghui Technology Co.,Ltd. provides natural mineral Kieselguhr filter aid in Sichuan, China.We devotes to ore mining, manufacturing and research. We have our own diatomite mine, research ourselves and purify by our own automatic production line which is the leading one in China.
Introduction of Chinese natural Kieselguhr filter aid
Diatomaceous earth powder is aquatic plant diatomaceous debris sediments, its is very tiny, the size is about 10 u - 30 u. Due to more than one thousand years of underground buried, then formed the diatomaceous earth ore. The main content is SiO2. It has a large number of microspore, non-crystalline SiO2. In addition, it also has little Al2O3,Fe2O3,CaO,MgO, K2O,Na2O,P2O5 and other organic materials.
Nowadays, The world wide used filter aid, 75%-80% is kieselguhr filter aid chemical. Its characteristic is to liquid pollution free, can remove 1 micron even 0.1 micron particle and bacteria. For example the usage of pool filtration
Our advantages
1. Our purify way: International advanced technology---Wet Cleaning Process
2. It maximizes reserve the kieselguhr's original structure
3. Keep a large number of SiO2: only the non-crystal SiO2 has the activity, we can keep 80% non-crystal SiO2.
