How Treated: Treatment of Cyanide Bearing Wastewaters
Water Innovations utilizes a 2-stage Cyanide Oxidation (CN) system that can treat from 2 GPM to 10 GPM. In the first stage of treatment, hypochlorite oxidizes cyanide to cyanate. It consists of two double-wall “Batch” Cyanide Oxidation Tank and an accumulation tank for cyanide-bearing rinse water, each tank equipped with one mixer. Wastewater containing cyanide will be pumped or flow by gravity into the first tank and then on to the second tank for complete cyanide oxidation. Both tanks have liquid level monitoring by an ultrasonic sensor to control incoming waste and outgoing solution transfers. The cyanide oxidation process would be controlled by level, pH & ORP sensors with electronic chemical metering pumps for NaOH, H2SO4, and hypochlorite addition with 4-20 mA control. All managed by Allen-Bradley CompactLogix (PAC) controller with touch screen (HMI).
