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. ...
