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 ...

Geobag, also known as a titan tube or geotextile tube, is a large, tube-shaped bag made of porous, weather-resistant geotextile and filled with a sand slurry, to form an artificial coastal structure such as a breakwaters, dune or levee. Geotextile tubes ...
ByEcoGeoX Limited based in Qingdao City, CHINA
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 ...

OUR measurements were made for two waste streams from a chemical production plant. The fingerprint for Waste 1 indicated the presence of three major groups of organic constituents. The first group of readily biodegradable organic constituents is oxidized at maximum kinetic rate through about one hour of contact. Oxidation of a second group of constituents causes the OUR to increase through about 3.5 hours of incubation. This increase in OUR is caused by growth of microorganisms during the oxidation reaction. ...

Oceanalpha’s autonomous hydrographic survey boat has been applied to the mining industry for tailings dam pond or tailing storage facility (TSF) surveys, in addition to its common application in lakes, rivers, reservoirs and oceans. All you need to do is set up the survey way-points and the drone boat will go automatically with GPS navigation and acquire online bathymetric data. USV survey technology has been proved to be a great alternative to replace traditional manned surveys, especially the surveys which ...
ByOceanAlpha Group Ltd. based in Wan Chai, HONG KONG
OceanAlpha makes unmanned surface vessels (USVs) for water quality professionals that sample, monitor, or survey large areas of water surfaces. Traditional methods require at least two technicians in a full-sized boat, going from site to site to collect samples or make measurements. The use of a USV reduces the amount of time, labor and equipment needed to collect water quality data when compared to traditional methods. Agencies have seen more than 6x more improvements in efficiency, while simultaneously reducing ...
ByOceanAlpha Group Ltd. based in Wan Chai, HONG KONG
OceanAlpha is developing an autonomous firefighting vessels that allows fast response times to fire dangers to improve the safety and security needs of maritime firefighting. The USV would assist in extinguishing the fire source first and foremost, as it has the greatest possibility of controlling the risk level. Since it is an unmanned vessel, it has the ability to complete close-range firefighting while keeping firefighters out of danger. It can also be utilized as a surveillance or rescue vessel in daily ...
