Introduction With the acceleration of urbanization, most urban sewage treatment plants are located on the outskirts of cities or densely populated areas. Malodorous gases generated during sewage treatment have become a major air pollutant. These unpleasant odors not only undermine the living quality of nearby residents but also contain harmful substances such as hydrogen sulfide and ammonia, posing potential risks to human health. In recent years, authorities have imposed increasingly stringent requirements on air quality, making odor control at sewage treatment plants a key part of environmental protection work. Against this backdrop, pellet activated carbon specially developed by Yihang for odor control in municipal sewage treatment has played a vital role in addressing this issue thanks to its outstanding adsorption performance. This article elaborates on relevant applications from multiple aspects below.
This article provides a comprehensive overview of 8-30 mesh and 12-40 mesh coconut shell activated carbon, core products in the water treatment industry. It clarifies the industry definition of "mesh", the particle size range and applicable scenarios of the two key specifications, sorts out the main categories and characteristics of water treatment activated carbon, and focuses on the core functions of coconut shell activated carbon in drinking water purification, including heavy metal adsorption, taste optimization and water softening. It also highlights the price trend from 2024 to May 2026: prices remained stable in 2024, continued to rise in 2025, and have surged sharply by May 2026, with a maximum increase of over 140%. The core driving factors of the price surge are analyzed, and professional suggestions on specification selection, cost control and procurement planning are finally provided.
The encyclopedia of activated carbon, a collection of knowledge, and technical guidance
Activated carbon, as a core adsorbent material, is widely used in critical fields such as drinking water purification, wastewater treatment, air pollution control, food and beverage decolorization, and gold extraction. The following is a summary of the world's ten leading manufacturers based on official data and industry information.
Jacobi coconut shell metallurgical activated carbon has become the first choice for many overseas customers, while products from ordinary suppliers also occupy the market with their own advantages. What are the differences between them? How to balance quality and cost in procurement? Let’s break it down for you below.
Overview of Activated Carbon。Activated carbon, also called activated charcoal, is a carbonaceous material with highly developed pore structure and strong physical adsorption capacity, produced by carbonization and activation of carbon-containing raw materials. Activation is the core process. Through physical or chemical methods at high temperatures, it etches carbon atoms and removes impurities to form abundant pores, greatly increasing specific surface area and adsorption performance.
Although there are many industrial wastewater treatment technologies available at present, very few can truly realize "resource utilization". The activated carbon adsorption and regeneration technology, by virtue of the unique properties of activated carbon, has exactly solved this issue and now has become a core force driving the resource utilization of sewage. This article will take you to learn in detail about several issues related to activated carbon sewage purification, including: What is activated carbon adsorption and regeneration technology? Why is this technology the "preferred solution" for sewage resource utilization? What are the advantages of activated carbon in sewage treatment? And what are the specific cases of activated carbon water treatment?
