“…Therefore, the choice of the appropriate plant is an important factor in phytoremediation processes [112]. Plants have been classified as emergent, submerged, or floating, and their use depends on the type of constructed wetlands [113]. Plants that have been applied in constructed wetlands for industrial wastewater treatment, include: Typha latifólia e.g., for distillery wastewater [114], slaughterhouse wastewater [115], petroleum refinery wastewater [116] and floriculture wastewater [117]; Phragmites karka e.g., for distillery wastewater [114]; Juncus effusus e.g., for winery wastewater [118]; Cyperus immensus e.g., for paper and pulp wastewater [119]; Phragmites australis e.g., for slaughterhouse wastewater [115], dye wastewater [120], textile wastewater [121], cork boiling wastewater [122], fish farm wastewater [123] and olive mil wastewater [124]; Brachiaria mútica e.g., for textile wastewater [120]; Typha domingensis e.g., for paper and pulp wastewater [119]; Canna indica e.g., for mixed wastewater from steel mill, paper and dyeing factory [125]; Pampas grass e.g., for glass industry wastewater [126]; Eichhornia crassipes e.g., for petrochemical wastewater [127]; Typha augustifolia e.g., for seafood processing wastewater [128]; Canna lilies e.g., for floriculture wastewater [117]; Pennisetum purpureum e.g., for swine wastewater [129]; Cyperus papyrus e.g., for sugar mill wastewater [130]; Phalaris arundinácea e.g., for tile drainage [131] and among others.…”

“…Although CWs are recognized for easy operation and maintenance, a low carbon footprint, lower maintenance (with little external energy input), and lower capital construction costs [113,[152][153][154], these systems have higher land area requirements and retention times than conventional systems [106,113,155,156]. The search for new plants to consistently comply with the permit requirements for removing pollutants has been a real challenge.…”

The transition from the linear economy paradigm to the circular economy in industrial wastewater treatment systems is on the global agenda. The search for new simple, eco-innovative, and low-cost processes for treating industrial wastewater, which can also be used by small and medium-sized industries, has been a constant challenge especially when environmental sustainability is considered. So, a new integrated industrial wastewater treatment system has been developed that includes the immediate one-step lime precipitation process (IOSLM) and atmospheric carbonation (AC), followed by constructed wetlands (CWs) or adsorption. The current review provides an overview of industrial wastewater treatment strategies for high- and low-biodegradable wastewater. A background on functionality, applicability, advantages and disadvantages, operating variables, removal mechanisms, main challenges, and recent advances are carried out for each process that makes up the IOSLM+AC+CW/adsorption integrated system. The prospects of the IOSLM+AC+CW/adsorption integrated system are also discussed. Not neglecting the improvements that still need to be made in the integrated treatment system as well as its application to various types of industrial wastewater, this review highlights that this treatment system is promising in industrial wastewater treatment and consequent by-product recovery. The IOSLM+AC integrated system showed that it can remove high amounts of organic matter, total suspended solids, oils and fats, phosphorus, and ammonium nitrogen from industrial effluents. On the other hand, constructed wetlands/adsorption can be alternatives for refining effluents still containing organic matter and nitrogen that were not possible to remove in the previous steps.

“…In articles I and II, we describe the use of P. australis and I. pseudacorus to remediate PTE from stormwater in terms of removal of nutrients and the accumulation of PTE (here Cd and Cr) in biomass using FTW technology. Such investigations could provide valuable insights into the economic benefits of this ecotechnology, as well as its potential to enhance the aesthetic appeal of the landscape and encourage community engagement (Sandoval-Herazo et al 2018;García-Ávila et al 2023). Studies on the pollution caused by PTE have received significant attention from researchers worldwide.…”

The impact of urbanization, industrialization, agriculture, mining, and stormwater runoff on ecosystems has resulted in significant water pollution concerns worldwide. Significant attention has been paid to the removal of potentially toxic elements (PTE) and metalloids (e.g., arsenic (As), selenium (Se) and lead (Pb)) by various plant species. However, little research has been published on the simultaneous accumulation of cadmium (Cd), chromium (Cr), and nutrient removal, by floating treatment wetlands (FTW), from stormwater runoff, and the accumulation and recovery of rare earth elements (REE) through energy biomass cultivation. This research bridges knowledge gaps in the remediation of REE using short-rotation willow (Salix spp.) and simulated stormwater remediation of Cd and Cr with Phragmites australis and Iris pseudacorus. In this context, three different microcosm experiments were conducted with perennial plants (P. australis and I. pseudacorus) in FTW. Stem growth, dry biomass, root length, chlorophyll content index (CCI), anatomical plant tissue changes, Cd accumulation and N and P removal from simulated stormwater were investigated over a 50-days period under different Cd doses (0, 1, 2 and 4 mg L−1). In addition, the effects of Cr dose (0, 500, 1000 and 2000 μg L−1) on the growth and anatomy of P. australis and I. pseudacorus, as well as on the accumulation of Cr in plant biomass and N and P removal were studied in FTW over a 50-day period. In addition, the effects of REE doses on stem growth, dry biomass, root length and their accumulation in biomass were investigated in two Salix species (S. myrsinifolia and S. schwerinii) and two cultivars (Klara and Karin) in FTW over a 28-day period. The REE treatments contained a single-dose of lanthanum (La: 50 mg L−1), multi-solute of six-REE (La: 11.50 mg L−1 + yttrium (Y: 11 mg L−1) + neodymium (Nd: 10.50 mg L−1) + dysprosium (Dy: 10) + cerium (Ce: 12 mg L−1) + terbium (Tb: 11.50 mg L−1)) and control (without REE). Moreover, REE recovery from biomass ash after combustion was investigated. In this study, P. australis and I. pseudacorus growth parameters were not hampered by Cd stress, their roots accumulated more Cd than the shoots and were capable of lowering N and P concentrations. The impact of Cr was more evident on plant growth under the low- and medium doses (500 and 1000 μg Cr L−1). However, anatomical changes were observed under the high dose (2000 μg Cr L−1, respectively). Both species were able to remove a substantial (98−99%) concentration of N and P within a 10-day period of increased Cr loading. The greatest amount of Cr was retained in P. australis and I. pseudacorus roots. Salix species and cultivars did not show REE toxicity symptoms and displayed a strong growth response compared to the control. All Salix accumulated REE in their biomass, although the greatest amounts of accumulated REE were found in the roots of the Klara and Karin cultivars. The substantial deposition of Cd and Cr in the roots of P. australis and I. pseudacorus, and REE in the Salix roots show their phytostabilization potential. Approximately 80% of the REE was retained in the Salix ash following combustion of the biomass at 1000 °C. The findings in this research reveal that these perennial plants could be suitable candidates to control the runoff from Cd, Cr and REE affected waterbodies into freshwater resources through immobilization aligned with efficient biomass production.

Constructed wetlands (CWs) are highly effective in wastewater treatment and have generated lines of research with a focus on technological development and implemented innovations. This work concentrates on the most recent technical and scientific advances that have obtained optimal results in the construction of CWs using sustainable materials and the use of ornamental plants and other aquatic plants. Efficiency is also documented through models and simulation with neural networks, the use of the random forest method, and the use of software such as MODFLOW, MODPATH, and COMSOL Multiphysics. The information shown is structured by geographical area and addresses regions of Africa, Asia, Europe, North America, South America, and Oceania. It is important to consider that the optimization and innovation of CW for pollutant removal may benefit developing countries that do not have sufficient infrastructure to meet the demand for municipal and industrial wastewater.
