In most commercial electrochemical processes, only one of the two sides of the cell produces a desirable reaction, whereas the complementary reaction at the other side simply avoids interference with the target process and/or offers fast kinetics as not to limit it. An overview of several possible paired reaction schemes and their advantages is given, accompanied with specific thermodynamic and kinetic selection criteria, cell and reaction design strategies, and examples from the organic, inorganic, and environmental areas. The unnecessary nomenclature dispersion in this field (e.g., combined, concurrent, conjugate, convergent, coupled, divergent, dual, duet, linear, paired, parallel, simultaneous and synchronous electrochemical processes) is revised and a simple, consistent classification, as well as a homogeneous schematization system, is proposed.

“…Treated effluent is used for irrigation. Wada and Naoi (1994) reported that ozone oxidation of cyanide wastewater combined with UV radiation can process cyanide into cyanate ion in a short time without addition of chemicals. Following ion exchange, the oxidized wastewater can be reused as rinse water in plating processes.…”

GENERALA major symposium on water reuse was cosponsored by the American Water Works Association (AWWA) and the Water Environment Federation (WEF). Proceedings from the symposium contain papers covering a wide variety of water reuse issues including planning, management, financing, marketing, design, and regulation (AWWA, 1994). Many individual papers from the symposium are cited in this review. Bastian (1994) presented an overview of water reuse in the U.S. and a brief summary of state-by-state water reuse practices. He noted that water reuse practices are regulated on a state-by-state basis because there are no national standards and that the largest reclaimed water demands in the U.S. are for agricultural irrigation and cooling water for thermoelectric generation, usually at sites near urban areas where reclaimed water is generated. Six research projects were identified as the most useful in advancing the state of knowledge in water reclamation and reuse of municipal wastewater (Crook, 1994). These projects include the following: microbial risk assessment monitoring, identification of new indicators of pathogenic microorganisms, evaluation of the effects of process selection on particle-size distribution, seasonal storage for reclaimed water, nonpotable water management, and evaluation of metals and synthetic organic chemicals in irrigation water. The evolution of AWWA policy on water reuse was de-,scribed by Bergman (1994). He noted that there are still many obstacles to be overcome, including acceptance of nonpotable reuse for edible crops and for use inside buildings. Survey results were presented on the potential for water recycling in California to the year 2010 and beyond (Kelly, J. et aI., 1994). All regions in California reported increasing use of recycled water. Sixtythree percent of respondents reported water supply as the leading reason for water recycling projects. At least $2 billion could be spent over the next 25 years on construction of water reclamation capital facilities. However, a water supply shortfall is expected by 2020 unless a goal of75% water reclamation is also achieved.Extensive bibliographies were published on the general topic of water reclamation (NERAC, 1994a and b). Specific topics examined included design, modeling, and evaluation of domestic, military, and industrial reclamation systems, as well as public attitudes, and government policy. Kindzierski and Gabos (1994) reviewed the potential diseases associated with water reuse practices such as lawn irrigation as well as other avenues of water contamination. Hespanhol and Prost (1994) presented several examples to illustrate the difference between guidelines and water quality standards for reuse and to show how countries have been adapting World Health Organization (WHO) guidelines to their situations to produce national standards on drinking water quality and the use of treated wastewater for crop irrigation. Microbial risk assessment modeling techniques have emerged as criteria for revising water reclamation regulations in Ca...
