“…(1), the Freundlich model is transformed into a linear equation where K f and 1/n are empirical constants which may be used to compare the P-sorption performances of either different sorption media being tested under the same conditions or one sorption medium tested under different conditions. log 10 q = (1/n) log 10 C e + log 10 K f (1) Sorption isotherms based on the results from the experiments with high and low C o values followed Freundlich model (Fig. 3); corresponding K f and (1/n) values were 0.25 and 4.66 for experiment A and 3.89 and 1.04 for experiment B, respectively.…”

“…This approach may be reliable and reasonably cost-effective at large WWTP, yet it is almost always technically and financially inappropriate for small communities (<2000 p.e.). The cost per gram of phosphorus removed is much higher for domestic wastewater treatment plants serving small communities since they are unable to achieve the same economies of scale achieved at large WWTP [1].…”

A B S T R A C TIn this work a tertiary horizontal-flow blast furnace slag (BFS) filter was tested for phosphorus removal under laboratory and field conditions. Laboratory experiments were conducted in a benchscale BFS filter for phosphorus adsorption capacity at equilibrium conditions using P-spiked water. On-site, the performance of a pilot-scale BFS filter was monitored for phosphorus removal from the final effluent of a pilot-scale WSP system located in Esholt (Bradford, UK), which comprises a primary facultative pond and a secondary aerated rock filter (ARF) in series. Adsorption capacity (q) results showed that BFS has high affinity for inorganic P species and it can remove up to 30 g P/ kg BFS; however, q values are strongly dependent on the initial P concentration. The pilot-scale BFS filter tested on-site performed better for longer (<2 mg P/L) than the laboratory-scale filter, even though despite the latter received the same hydraulic and P loadings (1.8 m 3 /m 3 d and 18 g P/ m 3 d, respectively). Both the laboratory and field results showed that BFS filters are an appropriate low-cost technology to upgrading small wastewater treatment systems for phosphorus removal.

“…The administrative entity plays a key role in the implementation and management of a trading program. State agencies should also commit to assume additional economic and regulatory responsibilities associated with the trading program (Keplinger et al ., ; Borisova and Roka, ). Trading partners need also to be assisted throughout the trade negotiations.…”

Increased regulatory attention in controlling pollutants has encouraged the development of water quality trading programs over the past several decades. These trading programs could provide the mechanisms to cost-effectively achieve water quality objectives. Encouragement of innovative methodologies for emission prevention and control, and the contributions from non-regulated pollution sources, are also important factors in the development of successful water quality trading programs. The objectives of this paper are to: assess the advantages of a trading program to reach water quality goals while providing additional benefits to the whole watershed; describe the challenges confronted during the design to implementation phases; and outline the essential elements of a successful program. A meta-analysis was also conducted using several water quality trading programs to assess main market-based elements driving the success of trading programs between point and agricultural nonpoint sources. Uncertainty, policy drivers and social embeddedness--the degree to which stakeholders are integrated into program development--seem to be the most influential determinant of program success. RÉSUMÉ L'instauration en perpétuelle croissance de nouveaux règlements pour la lutte contre la pollution de l'eau a encouragé le développement de nombreux programmes d'échange de crédits de la qualité de l'eau. Ces programmes pourraient constituer un outil efficace de gestion de la pollution de l'eau en vue d'améliorer à moindre coût la qualité des eaux. L'implémentation des techniques innovantes en matière de prévention et de contrôle des émissions ainsi que participation des sources de pollution non réglementées (par exemple agricoles) sont des facteurs importants et primordiaux sur le développement de ces programmes de crédit.L'étude envisagée présente les objectifs suivants: évaluer les avantages des programmes d'échange de crédits généralement élaborés dans le but d'atteindre les objectifs de qualité de l'eau tout en offrant des bénéfices supplémentaires à l'ensemble du bassin versant; identifier les incertitudes scientifiques et décrire les défis à lever dans les phases de conception et d'implémentation de ces programmes; et classer les éléments essentiels du développement d'un programme d'échange de crédits efficace.Une méta-analyse a été effectuée en utilisant des données des divers programmes d'échange (entre des sources ponctuelles et des sources diffuses agricoles) des crédits de la qualité d'eau dans le monde entier afin d'évaluer les paramètres essentiels influençant le succès de ces programmes. La variabilité, les règlements et l'intégration sociale--niveau le d'implication des parties prenantes dans l'élaboration du programme--s'avèrent être les facteurs les plus déterminants dans la réussite de ces programmes.

“…2) The water in the North Bosque watershed is relatively freeflowing, and the vegetation surrounding the river includes mainly hardwoods, conifers, and grasses (The Handbook of Texas online, accessed 2008). Major agricultural practices are present throughout the watershed, including the use of land for dairy farming, range cattle, forage hay, peanuts, and pecans (Keplinger et al 2003). The North Bosque River has been included on Texas's impaired water list since 1992 for excessive aquatic growth due to phosphorus overload (Keplinger et al 2003).…”

“…Around Lake Waco there are multiple camping sites as well as numerous hiking and biking trails (Texas Parks and Wildlife online, accessed 2008;Conry 2010). Aside from its use as a recreation area, pollution management strategies are specifically important for Lake Waco because it is the main source of public drinking water for more than 200,000 Central Texas residents (Keplinger et al 2003). The North Bosque watershed is a main contributor of water and, likely, pollutants to Lake Waco.…”
