Ibuprofen and Naproxen removal from domestic wastewater using a Horizontal Subsurface Flow Constructed Wetland coupled to Ozonation

Insights into the Kinetics Degradation of Bisphenol A by Catalytic Wet Air Oxidation with Metals Supported onto Carbon Nanospheres

“…By combining these parameters, the reaction rate (in mmol•g Ru −1 •min −1 ) can be expressed according to Equation ( 8 Ru (8) As in the previous case, the applicability of this equation was restricted to this installation and the range of operating conditions employed for the fitting of the experimental data: C BPA 0 = 5-30 mg•L −1 , T = 383.15-433.15 K, P = 20-50 bar, [CNS-Ru] = 0.50-1.50 g•L −1 , and 20 bar.…”

“…For this reason, different countries have proposed some restrictions and laws about BPA, such as Denmark, France, Sweden, Belgium, Austria, and Norway, being wholly forbidden in France and listed on the priority substance list in Norway [7]. Emerging pollutants are also called micropollutants, because they are found in concentrations between µg L −1 and ng L −1 [8,9]. The main problem of the emerging contaminants resides in the fact that they cannot be eliminated by conventional wastewater treatment plants (WWTP) [8].…”

The main problem of the emerging contaminants resides in the fact that they cannot be eliminated by conventional wastewater treatment plants (WWTP) [8]. Different concentrations of bisphenol A have been found in various effluents of WWTP, sludge, sediments, and rivers.…”

Wetlands for environmental protection

“…Similarly, another hybrid wetland system in which HSSF-CWs planted with Cyperus ligularis was coupled to an ozonation reactor and that was used to treat Ibuprofen and Naproxen. It was reported that the coupled system achieved 97% removal efficiencies of Ibuprofen and Naproxen, which were higher removal efficiencies than CW alone (Lancheros, Madera-Parra, Caselles-Osorio, Torres-López, & Vargas-Ramírez, 2019). Reyes-Contreras et al (2019) performed a comparative study to determine the maximum removal efficiency of 14 organic micropollutants, including analgesics/anti-inflammatories, anticonvulsants, stimulants, antifungal, fragrances, plasticizers, and transformation products in activated sludge (AS) and horizontal subsurface flow (HSSF) CWs.…”
