Coke wastewater is one of the most problematic industrial wastewaters, due to its large volume and complex pollutant load. In this study, ion exchange technology was investigated with objective reducing fluoride content effluent from a coke treatment plant (26.7 mg F-/L). Two Al-doped resins chelating aminomethyl-phosphonic acid iminodiacetic groups were assessed: TP260 TP207 resins, respectively. The effect resin dosage, varying 5 25 g/L, evaluated. F- removal within range 57.8-89.3%...

Coke wastewater is a complex industrial due to its high content of toxic compounds such as cyanides, thiocyanates, phenols, tar, oils, and fats. After series treatments, with ammonium obtained (around 4,150 mg·L-1). A stripping process used reduce it. Certain pollutants in the influent, polycyclic aromatic hydrocarbons (PAHs), fats total suspended solids (TSS), interfere therefore must be previously removed. In this study, performance pilot-scale airlift sand filter was evaluated under real...

This study investigates the human health risk of Al, As, Fe, Mn, Ni, Pb, Sb and Sr in dry deposition fraction settleable particulate matter (DSPM). Sixty samples were collected at an industrial suburban site (‘EMA’) a waterfront urban (‘Naval’) Gijón, coastal city northern Spain. Up to 4898.4 mg m−2 d−1 measured station closer activity. The levels eight elements greater this site. Fe Al major constituents, comprising up 50% DSPM. posed by DSPM was assessed using U.S.EPA methodology. level...

Due to the COVID-19 pandemic, lockdown restrictions were established around world. Many studies have assessed whether these affected atmospheric pollution. Comparison between them is difficult as periods of time considered are generally not same and thus, different conclusions may be reached. Besides, most consider mean daily pollutant concentration, despite differences being observed according day. In this study, hourly levels PM10, PM2.5 black carbon (BC) in an industrial suburban area...

Directive 1994/62 concerning packaging and waste 1999/31 related to disposal will substantially modify the management treatment of Municipal Solid Waste (MSW) in Europe. In this study, a life cycle analysis has been carried out different possibilities managing Asturias. The "Integrated Management" (IWM-1) model was employed, analysing alternatives for collection MSW. This predicts overall environmental burdens MSW systems includes parallel economical model. sources costs were considered...

Leachates produced in a simulated landfill pilot plant were compared with those at the Zoreda Asturias, Spain. Three loads of different amounts municipal solid waste (MSW) added to stages, thus forming consecutive layers. Up present, approximately 3 333 000 t (metric tons) MSW have been deposited 2.5 m high layers which are covered soil from surrounding area. The organic load leachates as COD decreased time both systems very initial values relatively low ones by end study, although they...

SOM-NG is a hybrid algorithm that able to carry out visualization of process data, nonlinear function approximation, classification and clustering. The supervised version produces new type 2D lattices called gradient planes which are useful determine the dynamics target variable according remaining training variables. In this way, it an interesting tool for data mining in order extract knowledge from databases systems. main objective work analyze industrial wastewater treatment plant using...

Numerous papers related to the estimation of wastewater parameters have used artificial neural networks. Although successful results been reported, different problems arisen such as overtraining, local minima and model instability. In this paper, two types networks, feed-forward gas, are trained obtain a that estimates values nitrates in effluent stream three-step activated sludge system (two oxic one anoxic). Placing denitrification (anoxic) step at head process can force denitrifying...

Objective: The objective of this study is to analyze the paradigmatic transition in solid waste management among Ecuadorian university students, evaluating evolution from conventional linear model a circular economy approach higher education institutions. Theoretical Framework: Solid represents global challenge that affects entire population. presented as comprehensive solution minimize generation, promoting recycling and reuse, well supporting local development reducing pollution. Method: A...

Abstract A general methodology is established that permits the characterization and evaluation of optimum potential biogas extraction at each vertical well in sanitary landfill Asturias, Spain. Twenty wells were chosen from a total 225 for study, maximum production flow biogas, which result degradation municipal solid waste deposited within its area influence, was determined well. It found this varied with time characteristic The extractable also as function composition needed subsequent...

Leachate produced at the Zoreda landfill in Asturias, Spain, was recirculated through a simulated pilot plant. Prior to recirculation said plant, three loads of different amounts MSW were added stages, thus forming consecutive layers. Up until present moment, approximately 3,333,000 Tm have been deposited 2.5 m-high layers which are covered with soil from surrounding area and slag nearby steelworks. The organic load leachate decreased rapidly initial values around 5,000 mg (Vl stable 1,300...
