Adsorbent for water treatment

Technology / Service Summary

Our adsorbents for water treatment are specialized for fluorine, arsenic, boron, and other elements that are difficult to process. We also handle products that can process general heavy metals.

Purpose

Efficient adsorption of elements that are difficult to process

Feature

・High adsorption performance
・High resilience to physical deterioration and low replenishment rate
・Adsorbent can be recycled and reused
・Stable treatment below the Japanese environmental standard (0.8mg/L, 1mg/L) (for fluorine and boron)
・Capable of treating extremely low concentrations below the detection limit (for arsenic)
・Cleared the elution test for water supply materials in Japan (for arsenic)

Effect

It has high adsorption performance and a long regeneration cycle, so it can reducing running costs.

Accomplishments

Countries: Thailand, Philippines, Malaysia
Example: At an automobile parts manufacturing plant, fluorine from hydrofluoric acid used in metal surface treatment was contained in the wastewater. Our fluorine adsorbent is used in the wastewater treatment, and the fluorine is treated to below the standard value stably.
