Company profile
Acro Chemical Corporation is a Taiwanese company specializing in the manufacture and reactivation of activated carbon, with a business role spanning liquid treatment and gas treatment. The company was established in 1987 in Kaohsiung, Taiwan, and developed pollution-control materials in response to Taiwan's industrial development and environmental-protection needs. Acro has served the activated-carbon industry for more than 30 years and develops products for semiconductor, electronics, food and beverage, water treatment, waste-plant, pharmaceutical, air-treatment and gas-purification applications. Its business combines activated-carbon manufacturing, carbon reactivation and the legal reuse of spent carbon within Taiwan. The company holds ISO 9001, ISO 14001 and ISO 45001 management-system certifications covering the manufacture and supply of carbon products, including regeneration activities. Its stated environmental and occupational approach links product and service development with environmental protection, professional safety, health performance and risk reduction. Acro provides customized activated-carbon products and assists customers in identifying suitable activated-carbon use for their requirements. The company's operating principles emphasize regulatory compliance, putting customer requirements first, fair transactions and competition, transparent internal management, and complete disclosure to customers. Those principles also include fulfillment of customer contracts, communication-driven customer satisfaction, timely service beyond the product itself, internal skills development and technical development. Safety is stated as a priority, while product and technology improvement are also directed toward reducing environmental impact. Acro's Douliu factory combines manufacturing and reactivation operations and uses equipment developed by the company to provide services for differing customer requirements. The Douliu operations include two plants and employ self-designed fully automatic and semi-automatic equipment for activated-carbon processing and regeneration. The factory's cooling system uses a dry design described as achieving zero wastewater discharge during the cooling process. Its rotary furnace uses liquefied natural gas, which the company associates with maintaining product quality and reducing emission pollution. Acro treats activated carbon as increasingly important for environmental control in semiconductor and panel manufacturing, electronics, petrochemical and other chemical industries, as well as for wastewater, waste-gas and waste treatment. The company's core-technology framework covers process technology, equipment-development technology and processing or reactivation technology, followed by after-sales support services. Its customer workflow is described from requirement confirmation through incoming material, material processing or reactivation and finished product, with personnel and product responses coordinated around the customer's need.
Exhibits
Acro Chemical Corporation offers six named activated-carbon product categories: Powdered Activated Carbon (PAC), Granular Activated Carbon (GAC), Extruded Activated Carbon (EAC), Bead Activated Carbon (BAC), Customised Activated Carbon (CAC) and Functional Activated Carbon (FAC). Activated carbon is produced from carbon-rich raw materials such as charcoal, shells and coal through carbonization followed by surface development and oxidative activation that increases adsorption capability. Its porous structure includes macropores, mesopores and micropores, and adsorption occurs through physical and chemical adsorption forces. The material can appear as cylindrical or irregular granules and as powder, with granular dimensions described as 1~6mm in diameter, lengths around 0.7~4 times the diameter, irregular granules at 4~40 mesh and powder at 40~325 mesh. Because different activated-carbon brands, specifications and raw materials have different pore-size distributions and intended uses, Acro advises selecting carbon according to the application rather than treating all activated carbon as interchangeable. Storage guidance calls for keeping activated carbon away from fire and heat, storing it in a cool and dry place, avoiding moisture and minimizing retained air that could reduce adsorption performance. Use guidance addresses oxygen-deficiency risk in confined spaces, personal protection for hands and eyes, careful opening of powdered carbon, and following instructions from Acro's technical personnel. Acro operates its own quality-control laboratory and evaluates activated carbon for both liquid-phase and gas-phase adsorption behavior. The laboratory conducts dynamic adsorption tests for liquid and gas applications so that activated-carbon behavior can be examined under application-oriented conditions. Testing methods are based on standards and methods including CNS, ASTM, AWWA, Japan JIS and JWWA references. Routine analytical items include moisture, hardness and particle-size evaluation. The laboratory also measures molasses value, methylene-blue adsorption, iodine value, bulk density, ash and pH as part of activated-carbon evaluation. Laboratory results are used with professional application advice to support selection of carbon for customer processes rather than only supplying a standard product. For liquid treatment, Acro lists coconut-shell activated carbon for drinking-water purification, where the objective is to remove impurities and odor from water. For semiconductor-related ultrapure-water demand, activated carbon is presented for water purification associated with wafer cleaning and removal of residual solutions such as hydrofluoric acid, including applications involving hydrogen-peroxide H₂O₂ removal. Wastewater-treatment applications use activated carbon when conventional treatment does not fully remove substances or odor or when additional treatment is needed to meet environmental standards. Other liquid-phase uses include industrial purification and decolorization as well as recovery of precious metals. Acro also provides activated-carbon reactivation as a service intended to restore adsorption capability and enable reuse of spent carbon. The stated reactivation sequence includes drying at 100-150°C, roasting at 400-600°C, activation at 850-1200°C and cooling after activation. Reactivation is positioned as a way to reduce discarded carbon and to reuse activated carbon after appropriate processing rather than replacing every batch with newly manufactured carbon. For carbon replacement projects, Acro's service process includes confirming the recovery requirement, delivering new activated carbon, replacing the carbon, cleaning the work area and handling the required declarations before returning recovered material for processing. The replacement service uses company vehicles as part of the collection and delivery workflow for activated carbon. Across manufacturing, customization, analysis, reactivation and replacement, the company presents an end-to-end activated-carbon service model for customers that need product selection as well as handling of used carbon.
