Shell activated carbon in wastewater treatment applications:
Because of activated carbon for water pretreatment requirements, and activated carbon is expensive, so in wastewater treatment, activated carbon is mainly used to remove trace contaminants in wastewater, in order to achieve the purpose of deep purification activated carbon treatment of wastewater containing chromium. Chromium plating in a larger amount of a metal material, hexavalent chromium in the wastewater are different in different form with pH activated carbon has a very well-developed porous structure and high specific surface area, with a strong physical adsorption capacity can effectively absorb wastewater Cr (Ⅵ). surface of activated carbon there are a lot of oxygen-containing groups such as hydroxyl (-OH), carboxyl (-COOH) and so on, they have electrostatic adsorption function of Cr (Ⅵ) to produce . chemisorption completely for the treatment of electroplating wastewater Cr (Ⅵ), adsorbed water can meet the national emission standards tests showed: the solution Cr (Ⅵ) concentration of 50mg / L, pH = 3, adsorption time When 1.5h, adsorption performance of activated carbon and Cr (Ⅵ) removal are the best results. Therefore, the use of activated carbon chromium-containing wastewater treatment process is physical adsorption on activated carbon solution Cr (Ⅵ) and chemical adsorption, chemical reduction and other combined result of activated carbon treatment of wastewater containing chromium, stable adsorption performance, high efficiency, low operating costs, there is a certain degree of social and economic benefits.
Yuxin activated carbon has been widely used in domestic, industrial, liquid adsorption, activated carbon water treatment, air purification activated carbon is especially suitable for power plants, petrochemical, refinery, textile printing and dyeing, food and beverage, pharmaceutical activated carbon, electronic high water, drinking life recycling water, industrial water reuse and other industries. more effective adsorption of free chlorine, phenol, sulfur, oil, resin, pesticide residues and other organic contaminants, chlorine, semi-dechlorination value, and an organic solvent Wait.
The company is specialized in producing series of water purification materials business, complete with independent import and export rights, the company is strong in technology, sophisticated equipment, advanced technology, long history of production, product quality Habitat forefront of the domestic industry.
