    Measurement of oxygen transfer from air into organic solvents Article (PDF Available) in Journal of Chemical Technology & Biotechnology 91(3):n/a-n/a November with Reads. dissolved oxygen content in water quality monitoring is an important indicator. Dissolved Oxygen (DO) refers to oxygen dissolve in water molecules state, DO is vital for all higher aquatic life (B.A. Cox,;M.A. Best, ). A source of DO is atmospheric oxygen infiltrate water body when dissolved oxygen in water is not.

      Gas mass transfer through the liquid-gas interface has enormous importance in various natural and industrial processes. Surfactants or insoluble compounds adsorbed onto an interface will inhibit the gas mass transfer through the liquid-gas surface. This study presents a technique for measuring the oxygen mass transfer through the air-water by: Measurement procedures for determination of α have been debated at length. Unlike clean water oxygen transfer measurement, no standard has been developed for process water oxygen transfer, however a standard guideline has been published by a joint committee of WEF and ASCE6.

    Field Measurement of Dissolved Oxygen Field DO Measurement()_AF.R4 Effective Date: Ap 1 General Information. Purpose. This document describes methods and considerations to be used and observed when conducting field measurements of dissolved oxygen . Oxygen mass transfer experiments were performed using a dynamic method based on the measurement of the concentration of dissolved oxygen in water. A step change in the concentration of inlet gas results in a dynamic response in the concentration of oxygen dissolved in the liquid phase, and these temporal concentration data are used to Cited by:

Abstract. Measurement of Oxygen Transfer in Clean Water was developed to calculate the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water.

The Standard is applicable to laboratory-scale oxygenation devices with small volumes of water as well as to full-scale systems with water volumes typical of those found in the activated sludge wastewater treatment process.

the Measurement of Oxygen Transfer in Clean Water. The Standard was subsequently improved, updated and republished in and will be published again in Following the development of the Clean Water Standard, it was realized that the next most important gap in knowledge was the characterization of process water transfer Size: KB.

oxygen transfer in clean water aeration systems may have a clean water efficiency of 6 to % SOTE/m and 3 to 4% Power Measurement • Since aeration systems are competitively bid on the basis of oxygen transfer per unit of power consumed, power measurement becomes very importantFile Size: 2MB.

Process water conditions for oxygen transfer are best described by mass transfer parameters. This dissertation focuses on quantifying the volumetric mass transfer coefficient, KLa, and the liquid film coefficient, KL, using dynamic surface tension (DST) measurements.

The maximum bubble pressure method was selected to measure DST because. Table of Contents for Measurement of oxygen in clean water: ASCE standard, ASCE/SEI / American Society of Civil Engineers, available from the Library of Congress. In order to evaluate the performance of different types of aeration systems, the American Society of Civil Engineers (ASCE) and US EPA jointly developed a standard for the measurement of oxygen transfer in Clean Water in The Standard was subsequently improved, updated, and .DIN EN Wastewater treatment plants - Part Measurement of the oxygen transfer in clean water in aeration tanks of activated sludge plants Kläranlagen - Teil Messung der Sauerstoffzufuhr in Reinwasser in Belüftungsbecken von Belebungsanlagen/5(5).In order to determine the standard oxygen transfer rate (SOTR) of the aerators in the carrousel, six experiments, according to the Dutch standard method (STORA, ), were carried out by previous investigators, in Augustas carrousel was first closed, and then it was filled with suitable clean water (16 mg COD/l).Cited by:
