“…Heavy metal concentration in soil was also estimated to study the interaction between contaminant free soil and effluent. Queiroz et al, 2017 andRamakrishnan et al, 2010 have discussed the interaction between heavy metals in effluent and soil and it is important to study the progress of metal ions in soil from effluent.…”

The present study aimed to investigate the bioaccumulation of heavy metals from the effluent of battery industry by an aquatic plant, Bacopa monnieri. Experiment was carried for 25 days and heavy metal concentrations were analyzed in plant parts (roots and shoots), soil and effluent using atomic absorption spectroscopy (AAS) for 5 days each. Parameters such as Translocation Factor (TF), Bioconcentration Factor (BCF) and Transposition Factor (TrF) were calculated to analyze heavy metal interaction between plant, soil and effluents. Zn and Mg were found to be high in TF, BCF and TrF, but Cr had a TF value higher than Zn as it translocates high amount of ions to plant parts. TrF values of contaminants increased constantly in the following order: Mg > Zn > Cd > Pb > Cr. TF and BCF values were not > 1 for toxic metals (Pb, Cr and Cd). B. Monnieri can be used as a phytoextractor in removing contaminants from aquatic bodies.

“…Among many macrophytes, Polygonum sp. and Eichhornia paniculata provided best accomplishment with respect to decrease in organic matter, i.e., 87.5 % and 90 % COD, respectively, and 79.6 % and 83.7 % BOD, respectively, from dairy effluents [94,95]. Bhutiani [96] described turbidity elimination up to 75 % and 54 % for plants like Eichhornia, i.e., 486 nephelometric turbidity units (NTU) and Lemna, i.e., 350 NTU, respectively, from dairy wastewater.…”

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.

The aim of this research was to evaluate the efficiency of horizontal subsurface flow-constructed wetlands (HSSFWs) planted with Hippeastrum striatum and Heliconia lastisphata for the treatment of contaminated river waters by wastewater from the dairy industry (WDI) and domestic wastewater in tropical climates over a study period of 136 days. Cell with a real volume of 780,000 mL and a flow rate of 1.805 mL s−1. The hydraulic retention time was determined to be 5 days. 12 individuals of Hippeastrum striatum were planted at a distance of 20 cm from each other in one cell, while in another cell, 12 individuals of Heliconia spp. were planted. An adaptation period was determined for both species. Subsequently, the experiment was started, and the elimination percentages obtained were as follows: COD: 67.94 ± 1.39%, 63.17 ± 2.63%; TSS: 56.49 ± 5.73%, 48.78 ± 5.87%; N-NH4: 51.06 ± 2.16%, 50.80 ± 1.91%; TN: 44.36 ± 5.73%, 30.59 ± 5.87%; TP: 47.00 ± 5.32%, 35.57 ± 4.06%; DO: 50.23 ± 1.61%, 47.74 ± 1.34%; and pH: 6.81 ± 0.07, 6.52 ± 0.1, for Heliconia lastisphata and Hippeastrum striatum, respectively. These results demonstrate that both macrophyte species can be used for the treatment of wastewater from the dairy industry using HSSFWs; cheese factories could be involved in the development of constructed wetland systems to reduce the environmental impact of the industry.
