Coconut Granule Activated Carbon for Ultrapure Water Purification
Description
Coconut Shell Granulated Activated Carbon (GAC) can be used for
Desulfurization.
Our product are widely used in air purification, atalyst carrier,
extraction of noble metal, solvent recovery and decolorization of
medicines, especially in treatment of industrial and drinking
water.
The production processes are accomplished by using one combination
of the following steps:
1.) Carbonization: Material with carbon content is pyrolyzed at
temperatures in the range of 600–900 °C, in absence of oxygen
(usually in inert atmosphere with gases like argon or nitrogen)
2.) Activation/ Oxidation: Raw material or carbonised material is
exposed to oxidizing atmospheres (carbon monoxide, oxygen, or
steam) at temperatures above 250 °C, usually in the temperature
range of 600–1200 °C. The product is also designed to comply with
all the applicable provision of ASTM standard for coconut activated
carbon.
Applications
The product is used primarily for electronics and semicon and
recycled water industry.

Advantages
With high quality coconut shell raw material and advanced pickling
post-processing technology,the coconut activated carbon has low
content of Fe, Na, K, Ca, Mg, Si and High mechanical strength, the
product has characteristic of pore developed, large capacity of
pores, good adsorption properties, low heavy metal content . it is
wildly used in electronics and semicon industry.It has excellent
removing efficiency for hydrogen peroxide, organic matter, Heavy
Metal, and residual chlorine in the recycled water.
