The water quality of the culture tanks was monitored by regular observations of the following variables: (1) pH (pH meter mPA210 - MS Tecnopon), (2) temperature and specific conductance at 0900 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) free C[O.sub.2] (titration with standard [Na.sub.2]C[O.sub.3] solution), (7) reactive phosphorus (molybdenum blue method), (8) total alkalinity (titration with [H.sub.2]S[O.sub.4] standard solution), (9) total hardness (titration with EDTA standard solution), (10) soluble iron (colorimetric Herapath method) and (11) total dissolved sulfide (titration with standard [Na.sub.2][S.sub.2][O.sub.3] solution).
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.sub.s], for steady state exhaust gas flow, i.e., constant velocity and temperature.
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.sub.4]) and (11) settleable solids (sedimentation in Imhoff cones).
Specific conductance of dilute solutions of propionic acid was read directly from the conductivity meter.
Following placement of the continuous temperature monitoring equipment, monthly site visits were made to all 8 streams and a Horiba U-10 water quality meter was used to measure water temperatures in [degrees]C, pH, specific conductance (mS/cm), and turbidity (NTU) of the surface, hyporheic, and spring water.
biggest specific conductance value and a greater effective surface area as shown in (1) in comparison with the reference all-metal electrode [R.sub.cu//Sn].
A digital meter (Dow Corning, Inc, Pocket Meter M90) was used to measure dissolved oxygen (DO 0.0 20.00 [+ or -] 0.1 mg/L), temperature (-0.5[degrees]C to 100[degrees]C [+ or -] 0.1[degrees]C), pH (0 to 14 [+ or -] 0.1 SU), specific conductance (0.0 to 1999 [+ or -] 1 [micro]S), and total dissolved solids (TDS; 0.0 to 1000 [+ or -] 0.1 mg/L).
The StREAM Lab currently has three sampling bridges with water-quality datasoiides that continuously measure dissolved oxygen, specific conductance, turbidity, pH, and termperature.
During each sampling effort, minnow traps were deployed; then, quality (temperature, dissolved oxygen, ph, specific conductance, and turbidity) and depth of water were measured at each trap.
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 663.14 micromhos/ cm and in post monsoon between 350 to 1367 micromhos/ cm with an average of 745.96 micromhos/ cm.
