In addition to their advantages as promising methods for wastewater treatment, CWs exhibit poor performance in terms of N and P removal efficiency the effluent treatment plants. By focusing on this issue, we designed integrated with a biochar-doped activated carbon cloth (ACC) electrode alum sludge from water plants substrate achieve concomitant organic matter nutrient efficiency. Compared use one layer (CWs-C3) ACC electrodes inserted two layers, which uses sludge, significant improvement was achieved (96% COD; 89% TN; 77% TP). The findings revealed that application potential accompanied by insertion cathode into first beneficial completing nitrification facilitating denitrification anode regions, respectively, resulting increased nutrients. Further evaluation TN-TP synergetic mechanism influenced Fe2+ an electron donor driving force development autotrophic denitrifying bacteria increase nitrate reduction. Additionally, formation FePO4 AlPO4 adsorption through interaction FeOOH AlOOH phosphate constitute main TP wastewater. Another reason CW-C3 reactor greater abundance microbial diversity effectuated regions. summary, strategy simultaneously promoting nutrients utilizing large scale practical applications proposed.

Chile has numerous areas that lack sewage collection, including in the capital city. Sanitation these cases is managed through individual solutions like septic tanks or small wastewater treatment plants (WWTPs) use biological treatment, usually activated sludge with extended aeration. In general, design of systems adheres to quality standards mandated by regulations for discharge, infiltration, irrigation. this scenario, traditional methods increasing dissolved oxygen (DO) hydraulic retention time (HRT) were unable effectively reduce excessive nutrients. Therefore, literature related nutrient excess and denitrification consulted reviewed compile different suitable presented issue. Potential modeled verified using free simulation software WRc STOAT. The accurately predicted unsatisfactory results current setup provided parameters proposed modifications. Experience, precise user definition, influential characteristics, modeling are essential WWTPs.
