Coconut Shell Activated Carbon And Textile Industry

Jul. 06, 2018

Coconut Shell Activated Carbon has good decolorization effect on dye wastewater. Coconut shell activated carbon is widely used in water treatment of food, beverage and pharmaceutical industries for pollution disposal, decolorization, deodorization, purification and as a catalyst in commodities. Indirectly added to the adsorption.

The adsorption effect of the coconut shell activated carbon with different components is superior to the similar shell carbon in the adsorption time and the loss effect. On the market, the common shell carbon (apricot shell, various types of core) can only reach the coconut shell activated carbon. About 80%, while coal, bamboo charcoal and charcoal can only reach 40%~60% of coconut shell activated carbon. Due to the particularity of Coconut Shell Activated Carbon Supplier offers coconut shell activated carbon raw materials, the market price of coconut shell activated carbon can clarify everything.

The development of the textile industry has led to the development of dye consumption. The survey indicates that the world's annual consumption of dyes exceeds 700,000 tons, of which 2% are indirectly discharged into the water body as waste water, and 10% are lost in the subsequent textile dyeing process. The dye wastewater has complex composition, large change in water volume, deep color, large concentration and difficult disposal. There are many disposal methods for dye wastewater, such as oxidation, adsorption, membrane separation, flocculation and biodegradation. Each of these methods has excellent defects. The adsorption method is to remove the purified substance by the adsorption of the adsorbent on the purified substance in the waste water. The adsorbent is a porous substance and has a large specific surface area. Coconut shell activated carbon is one of the most ineffective adsorbents at present, which can effectively remove the color and COD of wastewater.

The decolorization of acid fuchsin wastewater is the easiest, the alkaline fuchsin wastewater is the second, and the reactive black B 133 wastewater is the most difficult. The decolorization rate of dye wastewater is added with the decrease of temperature, and the pH value has little effect on the decolorization effect of dye wastewater. . Under the optimal adsorption conditions, the decolorization rates of acid fuchsin, basic fuchsin and and the activated carbon decolorization wastewater is the most difficult, the chromaticity concentration multiple of effluent was not more than 50 times, COD was less than 50mg/L, and reached. National first-level emission regulations.
