The drought in many parts of the U.S. so far this summer points out the preciousness of water supplies. Theres greater demand for waste-minimization and recycle-and-reuse technologies as well as more awareness of utility usage and the impact of life-cycle costs on water-treatment operations. Heres a look at new technologies that will help.
With increasing energy prices and public sensitivity to energy consumption, many plants are paying more attention to optimizing distillation. Simple and low-risk operational changes often can provide substantial savings.
A compact system significantly improves analyzer accuracy. This innovative turnkey solution for analyzer emissions is a solid-state pump with an ultra-sensitive pressure regulator that mixes a compatible gas with the analyzer samples to achieve a constant vent header pressure even during times of plant upset.
Guidance for chemical manufacturers, processors, and distributors about Section 8(e) of the Toxic Substances control act was issued on September 14, by the U.S. Environmental Protection Agency (EPA). Chemical Processing's Regulatory Editor Lynn Bergeson discusses the new regulation.
While fermentation-based syntheses were once reserved for producing high-value specialty chemicals and biopharmaceuticals, bioprocess routes now are gaining increasing attention for commodity products.

The Restrictions of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (the RoHS Directive) is part of a growing wave of European Union product-based regulations that will profoundly impact global and United States product standards and thus the chemical industry.
Because many environmental applications of nanotechnology will almost certainly revolutionize the science, law, and regulation of water pollution, readers are urged to keep abreast of this fast-changing area.
