Gujarat enviro-care industries is
the biggest manufacturers of wood activated carbon in
india
Detailed Description
Gujarat enviro-care industries is the biggest manufacturers
of wood activated carbon in india with the technology
from Institute of Chemical Industry of Forest Products
CAF and National Engineering &Technology Research Center
of Forest Chemical Industry. GUJARAT ENVIRO-CARE
INDUSTRIES its own scientific research team with 2
laboratories and 4 rotaries which are 42 meters length.
The main products are the activated carbon with phosphoric
acid method, zinc chloride method and steam method.
The highest methylene blue can be 300mg/g.
2.production process
Choosing the wood chips or sawdust from india as raw
material Sieving the raw material from wood sawdust to
be sure the material is without pollution from the
Purifying Device which is imported from Switzerland
Drying the sawdust in the Drying Equipment to control
the moisture be around 10 Adding the food grade Phosphoric
acid solution and catalyst to the dried sawdust to soak
for 30 mins Carbonized the wood sawdust which is with
phosphoric acid in the rotary under high temperature,
during the activation, the carbon molecular structure is
changing so that the hole space and the specific surface
area will be bigger Testing the semi product (testing the
product every 30 minutes, and 48 times a day) Acid
washing( washing the phosphoric acid and impurities to be
divided from the carbon Water washing (3 times by
boiling water, 2 times by cooling water Testing the semi
product (testing the product every 30 minutes,
and 48 times a day)à Drying and crushing (water and
particles control)à Packing the product.
