Aerobic Granule Reactor Technology
A new development for the treatment of domestic wastewater is a technology based on aerobic granular sludge. Granular sludge can be developed under specific process conditions. Because of the...
Workshop on Persistent, Bioaccumulative and Toxic Chemicals
The U.S. Environmental Protection Agency (U.S. EPA) is pursuing a number of initiatives dealing with various aspects of the identification and management of substances that are persistent, bio-...
Advanced Oxidation Processes for Water and Wastewater Treatment
The suitability of Advanced Oxidation Processes (AOPs) for pollutant degradation was recognised in the early 1970s and much research and development work has been undertaken to commercialise some...
Resource Recovery and Reuse in Organic Solid Waste Management
Uncontrolled spreading of waste materials leads to health problems and environmental damage. To prevent these problems a waste management infrastructure has been set to collect and dispose of the...
Identifying and Controlling Municipal Wastewater Odor Phase II
This project was undertaken in response to needs by the wastewater treatment industry to better understand the generation of odors from biosolids produced by wastewater treatment plants (WWTPs)....
Characterizing Mechanisms of Simultaneous Biological Nutrient Removal During Wastewater Treatment
Simultaneous biological nutrient removal (SBNR) is the removal of nitrogen and/or phosphorus in excess of that required for biomass synthesis in biological wastewater treatment systems where there...
Evaluation of Feasibility of Methods to Minimize Biomass Production from Biotreatment
This report presents the results of an evaluation of technologies that may result in less biomass production in activated sludge processes. The report summarizes the results of a comprehensive...
Use of Enhanced Biological Phosphorus Removal for Treating Nutrient-Deficient Wastewater
Anaerobic/aerobic (AnA) and completely aerobic (CA) laboratory-scale sequencing batch reactors operating on an acetate- and casamino acids-based synthetic wastewater were used to...
Use of Novel Techniques to Quantify Phenotypes in Biological Treatment Process
This research attempts to evaluate nitrification treatment performance in combined carbon/nitrogen municipal wastewater reactors using traditional physical/chemical methods and modern molecular...
Sensor Technology for Water Quality Monitoring: Bioluminescent Microorganisms
Biological wastewater treatment plants can be adversely affected by influent toxicity. The effects can range from poor clarifier biomass settling and elevated effluent BOD and ammonia levels to...
