  • Northwestern University and inCTRL begin Bioprocess Modeling Collaboration

    The research group of George Wells at Northwestern University is conducting a bench-scale investigation of shortcut biological nitrogen removal (scBNR) processes integrated with enhanced biological phosphorus removal (EBPR) and has teamed up with inCTRL Solutions to model these processes and perform predictive scenario evaluation in the SIMBA# simulation platform. Water resource recovery ...

  • Micro-bubble cleaning

    Genesol 703, our high ionic strength powder cleaner, has rapidly become our biggest selling cleaning product. It is particularly effective against clay and biofilm, which are notoriously difficult to clean. The product uses a unique cleaning mechanism, disrupting layered biofilm and clay at the membrane surface. This occurs via normal osmosis of water, drawn by the high ionic strength of the ...

  • EnviroSim Releases BioWin 5.1

    Building on the successful history of the BioWin line, BioWin 5.1 continues to provide rigorous mathematical models for wastewater treatment plant process simulation. The primary focus of this release has been to improve both steady state and dynamic simulation speed, particularly for (a) large flowsheets incorporating many elements; and (b) systems incorporating biofilm elements (e.g. ...

  • Wastewater treatment plant discharges can promote the development of antibiotic resistance in streams

    Widespread use of antibiotics has led to pollution of waterways, potentially creating resistance among freshwater bacterial communities. A new study looked for antibiotic resistance genes in a river basin in Spain, revealing that wastewater discharges can promote the spread of antibiotic resistance in streams and small rivers. Antibiotics are a cornerstone of modern medicine and have saved ...

  • Genasol 21cellulose acetate cleaner

    Membrane manufacturers specify strict parameters for membrane cleaning chemical use, including pH and temperature. Extremes of alkalinity and temperature can result in hydrolysis of the cellulose acetate, or polyamide, rejection layer of a membrane. Cellulose acetate is extremely sensitive to pH, and most membrane manufacturers recommend a pH of between of 3 and 9 for cleaning. These limitations ...

  • Bleeding Money in Plain Sight

    Chillers represent over 15% of a typical building’s energy use, but chiller efficiency is curiously often ignored as an opportunity to improve efficiency—pouring money down the drain via undetected fouling-related inefficiency. Manual cleaning of chiller tubes has represented the status quo for decades for chiller maintenance, even though our modern ...
