Odor control in sewers using calcium nitrate
Wastewater often creates nuisance odors. Effectiveness of Calcium Nitrate (trade name Bioxide) to control odors was investigated in the collection system of Clark County Sanitation District over a three month period in the summer of 1993. Bioxide feed stations were set up on the nine sewer lines …

Effects of holding tank odor control chemicals on aerobic wastewater treatment
Three odor control chemicals and formaldehyde were tested for detrimental affects on activated sludge using bench-scale bioreactors. Slug fed and continuous flow bioreactors were monitored for changes in suspended solids, specific oxygen uptake rate, sludge settling and compaction, and effluent …

Harmful algae, algal toxin, taste and odor control and mitigation in public water system
… MC-LR, cylindrospermopsin (CYN), and taste and odor (T&O) compounds. Various types of chemicals are widely used in drinking water treatment plants as oxidants for treating source water challenged with harmful algal blooms. In this study, the release and degradation of intracellular MC-LR due to …

The Effect of Cations on Volatile Solids Destruction, Odors, and Dewatering in anaerobic digestion
… feed cations on volatile solids destruction, odor control, and dewaterability. The role of influent feed cations and addition of chemical coagulants to sludge were evaluated for those characteristics following anaerobic digestion. Wastewater sludge samples were obtained from seven municipal …

Corona switching: an osmogene mitigation technique
Odorous gases such as hydrogen sulfide have long been associated with wastewater treatment plants, especially those with long forced mains which allow septic conditions to develop. With the encroachment of urban and suburban populations, many wastewater treatment plants are no longer located far …

The effect of three holding tank chemicals on anaerobic wastewater treatment
… boat operators add commercial preparations to control odors produced in their chemical toilets and holding tanks. The objective of this study was to determine the effects of three holding-tank chemicals on anaerobic wastewater treatment. Specifically, septic-tank performance with respect to …

Wastewater Carbon Diversion and Recovery via Primary Sludge Production, Thermal Hydrolysis, and Anaerobic Digestion
… dewaterability, and dewatered cake odor emission control. A comprehensive literature review showed that iron-based coagulants tend to show less negative impact than aluminum-based coagulants. This can be attributed to the reduction of ferric to ferrous ions in the course of anaerobic …

Investigating the Role of Various Environment and Process Conditions in Wastewater Sludge Odor Generation
… treatment facilities are known to emit malodorous odors causing public inconvenience. The odors typically comprise of reduced organo sulfur based compounds and nitrogen containing compounds. Lime stabilization is a technique which is commonly used in the wastewater industry to produce …

Characterization of Biogas from Anaerobically Digested Dairy Waste for Energy Use
… manure by addressing the principal problem of odor control while offering an opportunity to create energy from conversion of biogas with a system of combined heat and power (CHP). Anaerobic digestion is a microbial process that produces biogas, a gas consisting of primarily methane (CH4) and …

Sequential Anaerobic-Aerobic Digestion: A new process technology for biosolids product quality improvement
… attention to digestion efficiency. Noxious odor production from the land applied biosolids is another important issue related to digestion efficiency. Existing anaerobic digestion or aerobic digestion processes failed to provide simultaneous solution to biosolids related problems i.e. …

Quality and nutritional aspects of conventional and novel food proteins
… the potential cause and to characterize the sour odor associated with beef knuckles using microbial, odor panel, and gas chromatography-mass spectrometric (GC-MS) analyses. Knuckles (n = 10) identified as having no sour odor (control), slight sour odor (SLI-SO), or severe sour odor (SVR-SO) were …
