Wastewater containing cyanide will be pumped or flow by gravity into the first tank and then on to the second tank.  Depending on the other contaminants in the wastewater, the pretreated wastes from the second cyanide destruct tank can flow to the chemical reaction system prior to a microfilter or clarifier system.

The basic reaction system configuration has each tank equipped with one Brawn mixer, two LMI chemical feed pumps, one GLI pH probe, one Hach ORP probe and one Hach ORP transmitter.  On CN/CNP systems less than 1,000-gallon (3.8 m³) capacity, the mixing tank is mounted on a skid with a frame.

The frame supports the mixer, probes and chemical pumps.  The electrical control box, piping manifolds, conduit and wiring harnesses are also attached to this frame. When necessary, steps are supplied for operator access to the system.

CN/CNP systems above 1,000-gallons (3.8 m³)  are designed with a freestanding catwalk frame. The mixing tanks are slid into place underneath the catwalk frame.

Standard Available Options
