Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency

Tue, 27 Sep 2011 06:20:00 GMT

One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

Wed, 01 Sep 2010 05:28:00 GMT

Transfer of spectra used for calibrations is frequently used when large collections of spectra are difficult to reproduce. The effort to reproduce the calibration set is prohibitive or the samples that comprise the calibration set are ephemeral. By F. G. Haibach

White Paper: What Does Your Plant Spend On Raw Material Identity Verification? The Answer May Surprise You

Wed, 01 Sep 2010 04:39:00 GMT

Drug manufacturers must verify the identity of their incoming raw materials prior to release into the production process. For some, meeting this requirement involves extracting and testing samples from a small fraction of their incoming containers; for others it means testing every single package. As we trace both the apparent and hidden costs of laboratory-based identity testing, the answer may surprise you. By Thermo Fisher Scientific (formerly Ahura Scientific and Polychromix)
