The content of hexavalent chromium in industrial wastewater cannot exceed 0.5ppm.Since 2008, it has been stipulated that electrical and electronic equipment must not contain hexavalent chromium.
The ion exchange method for treating chromium-containing wastewater uses ion exchange resin to selectively adsorb hexavalent chromium in the wastewater, and then uses reagents to elute the hexavalent chromium, enrich and concentrate it, and then recycle it. Kingshan provides hexavalent chromium removal materials. For more details, please log on to www.bojieresin.com
