Zhongchuang has focused on the production and sales of activated carbon for decades. We are familiar with the application and common sense of activated carbon.
Due to differences in raw material processing, coal-based granular activated carbon and coconut shell granular activated carbon each have their own advantages in microporous structure, mechanical hardness, purification effect, and applicable water treatment and air purification scenarios. They are two commonly used and distinctly different adsorption materials in industrial purification.
Leveraging its developed pore structure and high specific surface area, coal-based granular activated carbon efficiently removes refractory organics, toxic substances from chemical wastewater, significantly reducing COD and color.
Premium coconut shell activated carbon efficiently adsorbs chlorine, odor and organics. Get reliable water purification solutions for your filtration projects.
High purity virgin coconut shell activated carbon specially produced for catalyst carrier & desiccant support. Excellent porosity, high mechanical strength and stable chemical property for industrial chemical applications.
Once coal-based granular activated carbon reaches adsorption saturation, its purification efficiency declines significantly. Therefore, it requires periodic replacement. Typically, a replacement cycle of 3 to 6 months is common.
From household water purification to municipal water supply, and from industrial ultrapure water production to the upgrading of various wastewater treatment systems, coconut shell activated carbon has emerged as the material of choice for water treatment, thanks to its superior adsorption capacity, higher structural strength, and excellent chemical stability.
For oxygen production, lithium molecular sieves (such as LiX type) or high-performance modified zeolite molecular sieves (such as 13X, 5A type) should be preferred. This type of molecular sieve has a higher nitrogen and oxygen separation coefficient and adsorption capacity. It can efficiently separate oxygen in the air and produce oxygen-rich gas with a purity of 90%-95%. It is suitable for medical, health care and industrial scenarios.
Activated carbon can effectively remove residual chlorine, odor, organic pollutants and some heavy metals in drinking water treatment, significantly improving water quality and taste. Its core function comes from its developed microporous structure and huge specific surface area (up to more than 1000m²/g), which can adsorb a variety of harmful substances and is widely used in household water purifiers and municipal water plants for deep purification.
Activated carbon mainly absorbs organic pollutants, pigments, odors, formaldehyde and other harmful gases, as well as some heavy metal ions. Its strong adsorption capacity comes from its highly developed porous structure and huge specific surface area (up to 500–1700m²/g), which can capture a variety of impurities through physical adsorption and chemical adsorption.
The process by which activated carbon adsorbs mercury relies primarily on its high specific surface area, well-developed pore structure, and surface chemical modification. The specific mechanisms can be broadly categorized into two modes: physical adsorption and chemical adsorption—with sulfur-loading modification significantly enhancing adsorption efficiency.
Choosing a desulfurization product depends on your specific application scenario and the type of sulfide being treated. Different industries, different types and concentrations of sulfides require significantly different desulfurization products and technologies.
Unlike zinc oxide desulfurizers, which are mainly used in medium-temperature, fine desulfurization applications, iron oxide desulfurizers offer unique and significant cost and operational advantages in their respective fields.
