Quality assurance and inspection of critical automotive components such as precision nozzles require metrology systems that can effectively combine both extremely accurate measurement and a high-level of process flexibility. To ensure robust performance over extended usage under very demanding environmental conditions, injector components must be controlled to very close tolerances across a number of different features, such as multiple diameters, length, taper, angles, and aperture ...
ByVIEW Micro Metrology based in  Rochester, NEW YORK (USA)
The inspection of electrical test probes requires precision metrology capabilities to accurately measure small features such as the positioning, pitch, and coplanarity of test lead ends. Fast and repeatable precision inspection processes often require a combination of multiple magnifications, high-performance video auto-focus with 50X lens, and/or through-the-lens laser options for rapid Z-axis ...

Measurement of oxygen uptake rates in activated sludge processes is essential to their satisfactory operation. Traditionally, oxygen uptake rates (OUR) have been determined by using a dissolved oxygen probe to measure the change in dissolved oxygen in a BOD bottle. While this method is rapid, it provides only a snapshot of the pattern of oxygen uptake in a treatment plant. Much more can be learned about the operation of a treatment plant by measuring the oxygen uptake rate over a period ranging from one to four ...

METHOD: A full-scale compost plant was faced with the need to determine the stability of the compost in the active bays during the compost operation. Samples were collected at 24-ft intervals (2 days of operation) through the length of one bay of the in-vessel compost system and placed into sealed glass reactors. Air was recirculated through the compost material using a peristaltic pump. A caustic scrubber was placed in the recirculation line to remove carbon dioxide (Figure 1). The reaction vessels were connected ...

A pharmaceutical company was interested in knowing whether a specific component, MCB, inhibited the biodegradation of other wastewater constituents. A series of respirometer tests was set up using identical mixtures of wastewater and return activated sludge (RAS) plus varying amounts of MCB. The OUR fingerprint of this wastewater includes a first peak of about 500 mg/L-hr within the first hour of contact that represents the oxidation of highly-biodegradable organic constituents. A second group of readily ...

METHOD: A seed culture from a full-scale anaerobic digester was placed in a number of 200 mL respirometer vessels. A synthetic wastewater having a 20,000 mg COD/L in a nutrient/ mineral/buffer solution was fed daily to each reaction vessel — along with various amounts of the cleaning agent The reactors were operated for a four day test period with measurement of gas production using a CHALLENGE ANR-200 anaerobic ...

Test Setup: A series of dilutions consisting of 50, 75, 100, 125, 150, and 175 mL of test wastewater were added to respective 500 mL respirometer flasks along with nutrients, minerals, and buffers. TCMP was added to eliminate interference from nitrification. Oxygen uptake was measured over a five-day test period using a CHALLENGE AER-200 ...

Method: An industry was discharging wastewater to a municipal sewer and was suspected of causing problems with treatment at the plant. Samples of the industrial wastewater were collected and oxygen uptake for four dilutions was measured using a CHALLENGE AER-200 aerobic/anaerobic respirometer system. Biodegradation kinetic coefficients were determined using the method described by Dang, et. al. (Res. J. of Water Poll. Control Fed., p. 1711, 1989). Results of the oxygen uptake measurements and kinetic analyses are ...

If industrial wastewater entering a treatment works contains toxic components the rate of biodegradation will be inhibited or stop completely. This can result in failed consents and will certainly give rise to operational problems. Visible indications include deflocculation, bulking and the appearance of filamentous bacteria. Sometimes, there are no visible effects. When the sludge bacteria are inhibited, there is the possibility of toxicity carryover in the effluent that is discharged to receiving waters. With ...

There are strict regulations in place surrounding waste water, which makes it very important to monitor. Even small changes in aquatic ecosystems can have a huge impact in the chemical makeup of water, temperature, etc. By using real time monitoring on water quality, pollutants can be detected and mitigated before they pose a potential threat to these ecosystems and enter the water course. The rugged AP-2000 allows for real time testing of wastewater and helps to minimise risk of any potential fines. It is works ...

Membrane technology has made major progress in recent years and is nowadays the method of choice for many processes in the chemical industry, wherever substances are to be separated efficiently and gently. A prime example of this is dia-filtration, in which solutes and particles with higher molecular weights are retained while solutes with lower molecular weights are "washed" out of the process fluid. ...
