“…This strategy efficiently eliminated mercury (Hg) and selenium (Se), two volatile metal pollutants. Di-methyl selenide [(CH3)2Se] is one method for decaying selenium [15,16] . This procedure can also be used to treat groundwater that has been poisoned with volatile organic chemicals such as perchloro-ethylene and trichlor-ethylene.…”

Massive amounts of wastewater (domestic, factories, and livestock) must be handled in an efficient, sustainable, and environmentally friendly manner as the world's population approaches eight billion. Wastewater-based hydroponic systems technology (HP) has the ability to generate economic benefits while effectively removing a broad spectrum of contaminants, including microorganisms, contaminants such as heavy metals, and new as well as old pollutants. This study aims to examine the foundations, applications, and restrictions of wastewater hydroponics technology in terms of pollution and nutrient removal. HP technique continues to have limitations, including high energy consumption, sophisticated control settings, and the unpopularity of using wastewater for agricultural seeding. Thus, more research is needed to reduce system energy use. Furthermore, further study should be conducted on hybrid technologies such as twostage hydroponics, which recycle contaminants from wastewater into nutrients for hydroponic plants by utilizing aquatic plants. The objective of this study is to give an in-depth examination of the basics, applications, and limitations of wastewater hydroponic systems technology in terms of pollutants and nutrient removal. Unlike constructed wetlands, wastewater hydroponic systems have been demonstrated to be effective in removing contaminants by a smaller scale in situ restoration. COD, TN, TP, Cu, Zn achieved overall removal rates that were exceeding event y percent, sixty percent, eighty percent, 64.2%, and 49.5 respectively.

“…94 Moreover, BESs have been proven to be greener and competent for the eradication of EC, for example pharmaceuticals, dyes, surfactants, and phenol from wastewater. 95,96 However, in the real eld various kinds of ECs are simultaneously present in wastewater, which are difficult to treat by the standalone technologies. 97 In typical BESs, such as MFCs, MECs, MDCs and MCCs, the fouling of membrane, meagre power production, high fabrication and catalyst cost and in case of MECs, the external power requirements for the remediation of various contaminants, are the major obstructions in the way towards the broader application of these technologies.…”

“…98 To overcome these hindrances, researchers have experimented with integrated BESs and hybridized BESs with other technologies such as constructed wetlands (CW), EF, adsorption, membrane bioreactors and also MECs integrated with MFCs, which were operated with the power drawn from the MFCs, and might prove to be a sustainable and economical alternative for remediating these ECs. 96,97 The AOPs can be used as a pre-treatment or post-treatment based on the wastewater's characteristics. For instance, if the wastewater has contaminants toxic to microorganisms, then AOPs can be used as pre-treatment to enhance biodegradability and make it amenable for biological treatment.…”

“…7, are widely implemented for textile wastewater, domestic wastewater, municipal wastewater, etc. Thus, it holds great scope for treating dairy wastewater [135,136]. Another modification can be an incorporation of microbial communities which can also increase the absorptive surfaces of roots, boosting metal uptake and the degradation of organic pollutants.…”

Dairy processing industries have emerged as the most swiftly evolving sectors with excessive wastewater generation containing proteins, fat, oils, greases (FOGs), etc. As there is rising strain on energy usage and dependence on water resources, sustainable research focuses on reduction in wastewater generation and developing value‐added goods. An effective and widely explored sustainable technique for treating wastewater is phytoremediation, a plant‐based process. This review aims to analyze phytoremediation as a sustainable alternative for dairy wastewater treatment. It initially briefs about dairy wastewater characteristics and treatment alternatives and discusses constructed wetlands and hydroponic system in detail with mechanism insights and influenced process parameters. Interconnected technologies with phytoremediation and their impact on contaminant transformations, nutrient reuse, and detoxification of pollutants are encompassed. Also, resource recovery and biomass utilization, feedstock enrichment along with the future prospects of integrated hydroponic systems for achieving sustainability with efficient resource recovery are featured.
