Wastewater Treatment by Azolla Filiculoides: A Study on Color, Odor, COD, Nitrate, and Phosphate Removal
The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation. The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

متن کاملSewage and Wastewater Odor Control
Sewage and industrial plants located near residential areas can be subject to political and legal problems if these facilities produce unpleasant odors. In the case of a sewage plant and the associated collection system, chemicals or enzymes may be added to the liquid phase to prevent the formation of the odors. Mechanical changes to the sewage pump stations may also be made to reduce the odor....
متن کاملMeasurement of Odor Threshold by Triangle Odor Bag Method
The detection thresholds of odor substances analyzed in field investigations were measured by the triangle odor bag method. The number of substances used for the experiment is 223. The experiment was carried out from 1976 to 1988. As the results of the experiments, the odor thresholds were distributed over the concentration of large range depending on the odor substances. Isoamyl mercaptane exh...
متن کاملOdor composition analysis and odor indicator selection during sewage sludge composting
UNLABELLED On the basis of total temperature increase, normal dehydration, and maturity, the odor compositions of surface and internal piles in a well-run sewage sludge compost plant were analyzed using gas chromatography-mass spectrometry with a liquid nitrogen cooling system and a portable odor detector. Approximately 80 types of substances were detected, including 2 volatile inorganic compou...
