Modern Concepts in Makeup Water Treatment

By Brad Buecker, Kiewit Power Engineers |

Water and steam are vital components of virtually all plants in the chemical process industries (CPI). And, a very important operation is the treatment of makeup water to produce the purity required for certain applications, most notably for use in heat exchangers and steam turbines. An important consideration in water treatment is that many industrial facilities are, or will soon be, dealing with tightening restrictions on wastewater discharges. These may include cooling tower blowdown, rainwater runoff and other aqueous discharges. As with other technologies, the processes utilized to produce high-purity water have been greatly improved over the last decades. This article examines several of the most modern techniques for makeup water production. These technologies are also being employed to reduce wastewater volume and to recover pure water for reuse in the plant. (For more on reuse strategies, see Strategies for Water Reuse, Chem. Eng. September 2009, pp. 34–39.)   Think twice about a clarifier Typically, the general makeup-treatment process involves: 1) large solids removal by screens or settling basins; 2) suspended solids removal; and 3) dissolved solids removal to produce the water needed for the process. We will focus…
