Carbon Limitation in Periphytic Algal Wastewater Treatment Systems
… of natural resource consumption. Wastewater treatment facilities (WWTF) are designed to destroy pathogens, remove particulates, lower oxygen demanding substances, and reduce nutrients from influent waste water to avoid the degradation of receiving waters. WWTF are generally effective, however …

Design of medical waste treatment systems employing bioremediation
… Investigation of the current commercial systems that accomplish this task shows that they all expose the waste to physical conditions that are harmful to all forms of life. Further, most are very expensive to install and to operate. A recently developed biochemical process promises to …

Spirasol : improvements to semi-continuous solar disinfection water treatment systems
… To address microbial removal capacity, the two systems were assembled and tested in Nairobi, Kenya and later in Cambridge, Massachusetts. The issue of economic feasibility and component availability were also addressed and factored in heavily during the design phase of the project. The results …

Evaluation of the performance of five aerated package treatment systems
… depend on septic tanks and other wastewater treatment systems for treatment of household wastes. The Joint Subcommittee Report HJR 7 1987 reported that sixty percent of Virginia's residential septic “systems and drainfields are operating improperly. With the demand for rural and suburban …

Water and Nutrient Use Evaluation of South Dakota Vegetated Treatment Systems
<p>Vegetated treatment system (VTS) effectiveness is governed by the system's ability to utilize applied water and nutrients. This study was conducted to determine whether existing VTS technology in South Dakota is effective at preventing release of water and nutrients from animal feeding …

Tracking Inorganic Solids in Biological Enhanced Phosphorus Removal Wastewater Treatment Systems
… modelling and tracking of solids in wastewater treatment plants (WWTPs) has historically been focussed on the different types of organic solids. Conversely, there is currently limited information on the composition of inorganic solids, and how they behave across different WWTP unit operations. …

Quantification of complex phosphorus removal reactions occurring within wetland filtration treatment systems
In a constructed treatment wetland applied to domestic wastewaters, long term studies and increased operational experience indicate that phosphorus removal is variable or inconsistent, especially in cold-climate applications. These inconsistencies can be attributed to the complexity of phosphorus …

Fate and Effect of Peracetic Acid Solutions on Biological Wastewater Treatment Systems
… pathogens. Upsets of biological wastewater treatment processes and failures of whole effluent toxicity (WET) tests have been reported as potentially caused by the excessive use of PAA solutions. However, information related to the fate and effect of PAA on biological wastewater treatment …

Removal of Estrogens at Full and Pilot Scale Livestock Manure Treatment Systems
… determine estrogen removal in different manure treatment systems; and 3) determine estrogen removal from dairy manure in pilot scale reactors. In Experiment I, the recoveries of 17Ã -estradiol (E2) and estriol (E3) were evaluated in double distilled water and dairy manure after a base extraction …

Investigating Ammonium Toxicity In The Performance Of Recirculating Periphytic Algal Wastewater Treatment Systems
… eutrophication, a threat to global aquatic ecosystems. Mechanical and chemical ways to curb this threat are either too expensive or not sustainable, and thus, not feasible. Compared to mechanical and other methods, sustainable, inexpensive biological methods (for example, algal treatment …

Water and Nutrient Balances of Vegetative Treatment Systems for Feedlots in South Dakota
<p>Vegetative treatment systems (VTS) are a possible alternative to storage basins for managing feedlot runoff but have not been researched in South Dakota. This study was conducted to evaluate the performance of VTS within South Dakota. The performance was evaluated by determining water and mass …

Investigating the relationship between nitrification and pathogen reduction in biological wastewater treatment systems
… to assess the potential of biological wastewater treatment systems in contributing to disinfection of municipal wastewater. The research focused on the microbial mediated processes occurring at secondary treatment and their effect on faecal coliform and E. coli numbers. The activated sludge system …
