Sichuan Honghui Technology Co.,Ltd. provides Diatomaceous earth 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 Diatomaceous chemical adsorbent:Diatomite 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. It is widely used as high quality Environmental diatomaceous adsorbent such as for water treatmentOur Product 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.

Applications
For water treatment
Characteristic and advantage:1.Stable performance2.Acid resistant3.High porosity and high absorbency. 4.High Specific surface area5.Easily operation, Recycle using of the filter6.Compact structure, small volume7.EconomicalFunctions:1.It can absorb the liquid weight 1.5~4 times of itself2.It can adsorb the oil weight 11~15 times of itself3.It can absorb the positive charge very good, it is widely used in waste water treatment and has the magic result, especially for deep cleaningApplications of using as water treatment diatomaceous chemical adsorbent:1.Edible water2.Swimming pool water3.Bathing water4.Hot spring5.Industry water6.Industrial waste water Filtration and treatment
Other Applications of being used as chemical adsorbent
1. Used as the adhesive in deoxidant for food fresh keeing
2. Used as dryer in electronic device, precise instrument, medicine, food and dress
3. Used as the soil regulator/ameliorant in Golf course, baseball field and lawn. To improve the area applicability for athletes when climate change
4. Used in pet animal husbandry as underbed of cat or dog.
