pHThe aim of this study was to achieve aerobic granulation utilizing fermented municipal wastewater under low pH, and alkalinity conditions. Stable granulation was achieved after a 166-day start-up period. Due to low influent strength, supplemental carbon addition, in the form of sucrose, was ...
The term "non-acidic fruits" might be a bit of a misnomer: Low-acid foods will still fall on the "acidic" side of the pH scale, but they'll be closer to that neutral 7. The pH value of 4.6 divides low- from high-acid foods. The greater the pH number, the less acidic the frui...

The smart control algorithms have been proposed considering all the aforementioned factors, and two scenarios are simulated to evaluate the benefits of the smart control algorithm. In the simulated case, the turbidity when the control algorithm is used represents 12.5% of the turbidity when not used...

Systems and methods are described for measuring pH of low alkalinity samples. The present invention provides a sensor array comprising a plurality of pH indicators, each indicator having a different indicator concentration. A calibration function is generated by applying the sensor array to a sample ...
