Advanced treatment technology for zinc-containing wastewater.

Introduction of advanced treatment technology that enables cost reduction and environmental impact reduction through wastewater recycling.

This document presents the features, examples, and technical information regarding the "Advanced Treatment Technology for Zinc-Containing Wastewater" conducted by Shin-Ei Chemical Industry. With the amendment of the law enacted in December 2016, the discharge standard for zinc was strengthened from 5 mg/L to 2 mg/L. Currently, the start date for implementation has been extended for another five years, but early action is required considering environmental impact. Our company has been engaged in the research and development of adsorbents with higher selectivity than conventional ones. We will introduce technologies that efficiently treat low-concentration zinc adsorption based on practical examples. [Features] - Multiple ions are present in the treated wastewater, but low-concentration zinc (10 mg/L) is selectively adsorbed. - Installation only requires the setup of a zinc adsorption tower, without the need for extensive renovation work. - The adsorbent can be repeatedly regenerated and reused. *For more details, please refer to the catalog or feel free to contact us.
