Environmental Technologies to Treat Nitrogen Pollution

Environmental Technologies to Treat Nitrogen Pollution will provide a thorough understanding of the principles and applications of environmental technologies to treat nitrogen contamination. The main focus will be on water and wastewater treatment, with additional coverage of leachates and off-gasses.

Monitoring Ammonia-Oxidizing Bacteria in Chloraminated Distribution Systems

Nitrification is a common operational problem experienced by utilities that chloraminate, arising from the associated addition and release of ammonia that can support the growth of AOB. Due to the slow growth of AOB, monitoring for nitrification events has focused on surrogate parameters instead of direct AOB enumeration. These surrogates can be influenced by factors other than nitrification and detectable changes in their concentrations can lag ...

Optimizing Biotreatment: Integrated Process Models and Control Strategies

The overall objective of this research project is to develop and implement model-based control strategies for improving biological treatment and document the methodology, benefits, and effort required. The project phase documented in this report include performing a literature review, installing extensive instrumentation at a full-scale advanced wastewater treatment facility, and developing real-time, dynamic models for biological nutrient ...

Resource Recovery from Wastewater: A Research Agenda for Australia

Traditionally wastewater treatment involved the removal of pollutants from wastewater to allow it to be discharged to the environment. This initially concentrated on carbon removal, but as environmental requirements became more stringent it was expanded to cover nitrogen and phosphorus removal. With increasing energy costs, more stringent environmental discharge limits and greater implementation of water sensitive urban design the economic ...

State of Knowledge of the Use of Sorption Technologies for Nutrient Recovery from Municipal Wastewaters Nutrients

The depletion of global phosphate rock stores and the energy intensity of ammonia production provide motivation for identifying alternative sources of these essential nutrients. The recovery of nutrients from wastewaters may be a viable nutrient source. Adsorption offers a highly efficient and stable, low cost technology for phosphorus (P) and nitrogen (N) removal; desorption of the nutrients from the sorbent will allow phosphorus and nitrogen ...

WEF/WERF Study Quantifying Nutrient Removal Technology Performance

The Water Environment Research Foundation (WERF) Nutrient Challenge Research Program and the Water Environment Federation (WEF) cooperated in a comprehensive study of nutrient removal plants designed and operated to meet very low levels of effluent N and P.  Both existing and new technologies are being adapted to meet requirements that are as low as 3 mg/L TN and 0.1 mg/L TP, and there is a need to define their capabilities and reliabilities in ...
