Noise is a problem that everybody in the world understands. When there is too much noise, or the wrong type of noise, people don’t like it and they complain. Businesses with noise issues have poor relationships with the community, which could quickly escalate to regulators enforcing restrictions on the non-complying party. We have over 40 years of applied noise management experience across a diverse range of industry sectors including mining, cities and heavy industrial operations. ...

There has been an increase in the use of autonomous patrol boats in extreme environments for reconnaissance and surveillance where demands for precision, endurance, and reliability are paramount. Maritime and border force customers work with us to develop unmanned patrol boats. At OceanAlpha, we have experience working with and developing various interfaces for propulsion systems, including outboard motors, diesel oil propellers, and water jets for high speed operations. Our USV is fitted with a high-resolution ...

Direct, Non-invasive Detection and Imaging of Groundwater to Depths of up to 500 feet (150 Meters). Surface magnetic resonance (also known as surface NMR, proton magnetic resonance and magnetic resonance sounding) is a powerful ground-based geophysical method used to non-invasively detect, measure and image groundwater. Vista Clara’s GMR and GMR-Flex multi-channel surface NMR instruments work by using the same physics as medical MRI. Surface magnetic resonance measures hydrogen protons in groundwater to ...

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 ...
