So, what is the next step for USV technology? Developing larger, longer endurance USVs and taking them beyond shallow waters. OceanAlpha has continued its quest to develop autonomous vessels, integrating them with multibeam sonar, sub-bottom profilers, side scan sonar, CTD, SVP, and LiDAR capabilities for the oceanographic survey community. OceanAlpha’s USVs have been placed with lead users in the markets and have been applied from coastal oceanographic surveying to open sea areas, including the Antarctic ...

Standard Biopsy Limitations Traditionally, men suspected of prostate cancer undergo systematic biopsies guided by ultrasound imaging. Because ultrasound offers poor cancer visualization, 12 random samples are taken without knowing if there is cancer and if so, where it is. As a result, the cancer is either missed entirely, or if detected, is difficult to determine the extent and severity. This leads to under treatment of men with serious disease and overtreatment of men with indolent disease.4 ...

Wastewater treatment plants face the need to manage their costs, and one of those costs is in heating cold, untreated sludge to the required temperature. That investment in energy is then lost when the waste flow is released. DDI'S direct sludge-to-sludge heat recovery system pumps incoming sludge through a system of rectangular channels, so it absorbs most of the energy in the hot wasted digested sludge. With DDI Heat Exchangers, there is low risk of plugging due to very large gaps, and the risk of baking to the ...

Robotics and underwater vehicles have been used in the oil and gas industry for decades. Without the use of autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs), the industry would be far less efficient than it is today. In recent years, unmanned surface vehicles (USVs) were introduced to the industry and offered a variety of solutions that aided in lowering costs and improving the efficiency of offshore operations. OceanAlpha has been working with oil and gas customers to provide innovative ...

The CHALLENGE AER-200 Respirometer System consists of one or more biological reaction vessels, gas flow measuring cells, and a computer. The gas measuring base contains eight flow ceHs and associated interconnecting circuitry. As gas flows through each cell under the influence of a slight pressure caused by gas production in the reaction vessel, bubbles of a fixed volume are formed in the lower section of the cell. These bubbles in turn pass through a detection section where a counter is activated. Finally, the ...

Heating water for showers, laundry, dish-washing and other uses costs you money - and it's money that literally flows right out of your building and into the sewers. Fight back by installing a DDI heat exchanger that circulates that waste heat past the incoming cold water flow. The heat exchanger warms the incoming flow, reducing the operating cost of your water heaters, boilers, laundry operations, dishwashers and other energy users. Savings can be considerable, and ongoing. For example, consider a hotel, with ...

Waste Type: Complex alcohols. Objective: Certain constituents of the test waste were know to be biodegradable but were suspected of being toxic to aerobic biological processes when present in high concentrations. The objective was then to determine how much waste could be added to an activated sludge process before toxic impacts would be ...

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 ...

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 ...

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 ...

Test Setup: 40 and 60 mL of wastewater were added to individual respirometer flasks each containing nutrient/mineral/buffer medium to form two different dilutions. TCMP was added to inhibit nitrification. 25 mL of seed from a laboratory scale reactor was added to each test reactor. Oxygen uptake was monitored using a CHALLENGE AER-200 respirometer for five days. A second dose of 40 and 60 mL of leachate sample was then added to each reactor and oxygen uptake was measured for another 5 ...
