It is an essential technology for processing to below environmental standards because it can be stably handled at low concentrations.
Our company proposes an adsorption method using the arsenic adsorbent "READ-As" for treating arsenic-contaminated water. The adsorption method removes arsenic from the liquid by passing raw water through a tower filled with the arsenic adsorbent. Since treatment can begin immediately after the installation of the adsorption tower, it is possible to respond even in urgent situations, and operational management is relatively easy. 【Features】 - Capable of adsorbing and removing both trivalent and pentavalent arsenic forms in water without pre-treatment. - The arsenic adsorption capacity is very high, allowing for stable treatment of arsenic concentrations below target levels for an extended period. - Capable of treating to environmental standards of less than 0.01 mg/L, etc. *For more details, please download the PDF or feel free to contact us.
