Chapter 3 - Removing Nickel from Wastewater

The existing treatment strategy is to precipitate the nickel ion as Nickel Hydroxide (Ni(OH)2). The soluble nickel remaining after precipitation is less than 1 ppm, which is a design specification. During the course the plant operation, some cyanide ion is inadvertently added to the waste stream. The soluble nickel is now in excess of 1ppm.
