TB 43: Efficient ammonia removal using modular liqui-cel contactors
Ammonia is widely used in the Chemical Industry as a cleaning and bleaching agent in the production of fertilizers, plastics, and explosives just to name a few. As a result, large quantities of wastewater containingammonia are produced and many industries now have to treat the wastewater to remove the ammonia so that it is not discharged back into the environment. There are many conventional ...

From Wastewater Treatment to Sweet Pineapples
In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking. Sulzer offers modern closed-air-loop systems for wastewater treatment that transform ammonia into a common soil fertilizer. This reuse of a waste product ...

Landfill leachate treatment for biological nutrient removal from wastewater
Substantial volumes of leachate have been generated at the recently opened lined cells of the Orange County Landfill located in central Florida. To accommodate these volumes, a force main was installed to deliver leachate to the Eastern Service Area Wastewater Treatment Facility (ESAWTF) operated by the Orange County Public Utilities Division, which uses a biological nutrient removal process. ...

Ammonia nitrogen removal from acetylene purification wastewater from a PVC plant by struvite precipitation
Acetylene purification wastewater (APW) usually contains high concentrations of ammonia nitrogen (NH4-N), which is generated during the production of acetylene in a polyvinylchloride manufacturing plant. In this study, a struvite precipitation method was selected to remove NH4-N from the APW. Laboratory-scale batch experiments were performed to investigate the effects of the initial APW pH, ...

Kinetics of organic matter and ammonia removal in horizontal reed beds treating wastewater in Nepal
In Nepal, both horizontal bed and vertical bed subsurface flow constructed wetlands have been used for wastewater treatment. However, these units were designed based on the empirical findings from other countries. The rational design criteria developed so far has some limitations as the performance of the units is sensitive to the behaviour of the microorganisms, climatic conditions and other ...

Role of ammonia-oxidizing bacteria in micropollutant removal from wastewater with aerobic granular sludge
Nitrifying wastewater treatment plants (WWTPs) are more efficient than non-nitrifying WWTPs to remove several micropollutants such as pharmaceuticals and pesticides. This may be related to the activity of nitrifying organisms, such as ammonia-oxidizing bacteria (AOBs), which could possibly co-metabolically oxidize micropollutants with their ammonia monooxygenase (AMO). The role of AOBs in ...

Trickling filter design guideline – How do trickling filters work?
Please watch the video tutorial here: https://youtu.be/r-0wRzGbSqw Trickling filters are biological reactors within wastewater treatment plants which are used to remove organic matter and/or ammonia from wastewater. Compared to the activated sludge process the microorganisms are not suspended in the mixed liquor but they are attached to a fixed bed surface. Nowadays, the fixed bed surface is ...
