As reported on ChemicalProcessing.com - The drought in many parts of the U.S. so far this summer points out the preciousness of water supplies. The chemical industry cer-tainly didn’t need the weather to sensitize it to the importance of optimizing water use (see www.chemicalprocessing.com/articles/2005/571.html). There’s greater demand for waste-minimization and recycle-and-reuse technologies, says Hari Gupta, Schaumburg, Ill.-based director of application engineering for the build-own-operate group within Siemens Water Technologies Corp., Warrendale, Pa. There’s also more awareness of utility usage and the impact of life-cycle costs on water-treatment operations, he adds.
