Essential for treatment to meet the water supply standard! An effective method for arsenic removal from well water.
We would like to introduce our recommended technology, the "Adsorption Method" for arsenic treatment. This technology removes arsenic from water by passing the target water through a tower filled with an adsorbent. Our arsenic removal adsorbent "READ-As" has numerous achievements both domestically and internationally, and can be used not only for well water treatment but also for factory wastewater treatment and mineral water production. (We offer regeneration at our factory.) Please feel free to consult us when you need our services. 【Benefits of Treatment with the Adsorption Method】 ■ Stable treatment is possible ■ Low operational costs ■ No waste generated on-site ■ Easy maintenance ■ Capable of treating trivalent and pentavalent arsenic without pretreatment *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Arsenic Treatment Methods (Part)】 ■ Adsorption Method - Treatment Features: Raw water is passed through a tower filled with adsorbent to adsorb and remove arsenic. - Saturation: The adsorbent is regenerated for recovery. - Advantages: It can selectively remove arsenic, allowing for stable treatment over a long period. - Disadvantages: There is a limit to the adsorption capacity, so if the raw water concentration is high, breakthrough occurs in a short period (consideration of combined use with coagulation and sedimentation due to short breakthrough time). - Low Concentration Treatment Limit: Inorganic arsenic can be treated to below the detection limit (organic arsenic is not subject to treatment). *For more details, please refer to the PDF document or feel free to contact us.
