The treatment of dye wastewater is urgent, so how should we treat it better?

The methods of dye wastewater mainly include membrane separation method, ion exchange method, biodegradation method, chemical precipitation method and adsorption method. Powdered activated carbon uses high-quality wood chips and nut shells as raw materials and is produced by the zinc chloride method. It has a developed mesoporous structure, large adsorption capacity, and rapid filtration. Coconut shell activated carbon is made of high-quality coconut shell through a series of production processes. Coconut shell activated carbon is black in appearance and granular. It has the advantages of developed pores, good adsorption performance, high strength, easy regeneration, economy and durability. The products are mainly used for the purification, decolorization, dechlorination, and deodorization of drinking water, purified water, wine making, beverages, and industrial sewage; it can also be used for desulfurization in the oil refining industry. Among them, adsorption is recognized as one of the most effective and lower-cost treatment methods, and is more suitable for large-scale industrial applications. Water purification activated carbon is used to treat industrial wastewater such as dye wastewater. Powdered activated carbon for water purification is an excellent adsorbent, especially suitable for decolorization of wastewater. Removal of color, odor, organic matter and other harmful substances in dye wastewater. The results show that the adsorption and regeneration of dye wastewater by activated carbon has important practical significance to reduce environmental pollution, save costs, and promote the development of activated carbon treatment of dye wastewater.
