Integrating Aeration Control Solves Underperformance
The referenced article is an accurate reflection of the state of our industry. Unfortunately, “problem aeration” is a common deficiency that exists in many plants. This deficiency directly impacts a utility’s ability to optimize the performance of secondary treatment and the largest use of power at the facility, aeration. To better understand this commentary, it’s prudent ...

Removal of ammonium ions from wastewater: A short review in development of efficient methods
Ammonium ions wastewater pollution has become one of the most serious environmental problems today. The treatment of ammonium ions is a special concern due to their recalcitrance and persistence in the environment. In recent years, various methods for ammonium ion removal from wastewater have been extensively studied. This paper reviews the current methods that have been used to treat ammonium ...

Cold weather ammonia reduction in municipal/industrial treatment plant case study
Problem During cold weather this municipal wastewater treatment plant with a high percentage of industrial flow from food processing and electronics manufacturing suffered from high ammonia loadings. As temperatures dropped the plant lost nitrification. The objective of this full-scale product application program was to reestablish ammonia oxidation and reduce ammonia-nitrogen in the lagoon ...

Success of Onlin Leads to Closing for Wastewater 2 Process Control of Consent Order Treatment Plant
In 2003, Plant City, a small Florida city of 30,000 residents, faced a very big problem. The Florida Department of Environmental Protection (FDF.P) determined that the city's wastewater treatment plant was not consistently operating within its permit limits, and placed it under a consent order. Plant City is a highly industrialized area. "Our industrial loading is very diverse and includes metal ...

Full-scale experience with the deammonification process to treat high strength sludge water – a case study
More stringent effluent criteria with regard to nitrogen calls for improved nutrient removal techniques in wastewater treatment plants (WWTPs). Besides optimisation of the liquid treatment train of the plants, attention has increasingly centred on the problem of return flows from sludge treatment. One of the most recent developments aimed at the reduction of this nitrogen load is deammonification ...
