Since the cycle starts at the conclusion of the regeneration procedure with a clean sensing surface and is concluded when triggered by a specific conductance
reading, one may assume that a specific sensor conductance is represented by the same mass of soot accumulation, [M.
The sampling process involved the routine measurements of pH, temperature, specific conductance
, and dissolved oxygen.
Water quality of the tanks was monitored by determination of the following variables: (1) pH (pH meter mPA210--MS Tecnopon), (2) temperature and specific conductance
at 0800 and 1500 (conductivity meter CD-4303--Lutron), (3) dissolved oxygen (0800; dissolved oxygen meter YSI 55), (4) total ammonia nitrogen (TAN; indophenol method), (5) nitrite (sulfanilamide method), (6) nitrate (Cd reduction technique), (7) reactive phosphorus (molybdenum blue method), (8) total alkalinity (titration with H2SO4 standard solution), (9) total hardness (titration with EDTA standard solution), (10) organic matter (consumed KMn[O.
of dilute solutions of propionic acid was read directly from the conductivity meter.
unpublished data, 2008); however, this study differs from the HSI in that continuous water temperature monitoring was completed, and dissolved oxygen (DO), pH, specific conductance
, and turbidity were measured consistently (monthly) for 15 months.
biggest specific conductance
value and a greater effective surface area as shown in (1) in comparison with the reference all-metal electrode [R.
is a measure of the ability of a substance to conduct electricity across a unit length at a specific temperature.
For the 36 individual permits that are the subject of the hearings, the EPA has been working with KDOW to collect and evaluate data on toxic metals, cyanide, phenols, specific conductance
, and current biological health of the waters that receive discharges from the mines in an effort to work through the issues identified in the objections.
The StREAM Lab currently has three sampling bridges with water-quality datasoiides that continuously measure dissolved oxygen, specific conductance
, turbidity, pH, and termperature.
Measurements of specific conductance
(mS/cm @ 25[degrees]C) were converted by the electronic meter to salinity by using the formula, [salinity.
The specific conductance
values are found to be within the range of 346 to 1173 micromhos/ cm at 25[degrees] C in the pre monsoon with an average of 663.
The following stream variables were analyzed in each sampling: depth, water temperature, turbidity, specific conductance
, pH, dissolved oxygen and current velocity.
