• Characterizing effluents from PECVD, plasma etch processes
  . Quadrupole mass spectrometry (QMS) was used as the analytical method in the study because of its high sensitivity, large linear dynamic range, speed of response, and ability to withstand the reactive, corrosive nature of the effluent streams being analyzed. On-site calibrations of QMS response...
• Blue Lagoons on Pig Farms?
  Patricia Millner, a project cooperator from ARS's Environmental Microbial Safety Laboratory in Beltsville, Maryland, "This prevents dispersion of pathogens into soil, water, or air when the treated effluent is sprayed onto fields or recycled into storage ponds.". Indeed, the evaluation site's old...
• New advances in microparticle retention
  results in increased paper machine and additive efficiency, and reduced effluent loading (e.g. filler, starch). The cost saving associated with a higher overall retention of additives can be significant. The use of microparticle/ microflocculant products promote improved z-direction filler distribution...
• MICRO: Green and Clean - Brown (March 2000)
  amount of effluent as well as on the amounts that were segregated as reusable water or waste. The meters were a necessary part of the evaluation because the CMP process tools consume UPW at different rates when processing and when idle. Sampling ports were also installed in the escape lines to enable...
• Improving tungsten CVD performance with in situ particle monitoring
  with the calculated detection area of a 1.5-um-diam particle. A third calibration point may further enhance the accuracy of the detection area for particles >=0.5 um. In addition, the sensor location and bulk flow properties of the effluent sample may have introduced additional bias within this particle...
• Less is More in API Process Development
  . The effluent water after use was treated with the best available technology and sent back to the river. Now let’s consider the alternative: conducting this reaction at room temperature. This approach could be safely taken if one follows the reaction chemistry along with physical chemistry. A back mix...

Many chemical companies are limited or regulated by the EPA for waste water (effluent) production as. well as emissions. In some cases there are limits to the amount of physical product they can ship...
