Investigation of Phasic Process of Biogas Yield by Measuring pH, ORP and Electrical Power Changes
Background & Aims of the Study: Studying the phasic process of the biogas yieldis required to optimize the design and operations; it also helps to lower energy production costs by decreasing the capital investment and operational costs. Here we determine the biogas process by measuring pH, ORP, electrical power and make compatibility to the biogas production trend. Materi...
متن کاملRegulation of Denitrification Using Continually Measured ORP and pH Signal
The use of pH and oxidation-reduction potential (ORP) as control parameters for the nitrificationdenitrification process is compared and discussed. The signals were measured in a sequencing batch reactor activated sludge system and in a completely mixed activated sludge reactor. The termination of denitrification was clearly identified not only by an ORP signal, but also by a pH signal. However...
متن کاملPhysicochemical and ion-binding properties of highly aliphatic humic substances extracted from deep sedimentary groundwater.
Humic substances (HSs) are ubiquitous in various aquatic systems and play important roles in many geochemical processes. There is increasing evidence of the presence of HSs in deep groundwater; nevertheless, their ion binding properties are largely unknown. In this study we investigated the physicochemical and ion-binding properties of humic and fulvic acids extracted from deep sedimentary grou...
