“…However, plants can also affect microbial activity, for example, resulting in immobilization of available ammonium ( Skiba et al, 2011 ), and either increase or decrease nitrification depending on the plant species and soil ( Skiba et al, 2011 ; Thion et al, 2016 ; Norton and Ouyang, 2019 ). Although our experimental design does not allow us to decipher the mechanisms, allowing plants to grow in the barriers makes the system resemble a vertical sub-surface flow constructed wetland or reedbed ( Vymazal, 2007 ; Al-Ajalin et al, 2020 ), a design that has proven to be efficient in the removal of nutrients and organic material from domestic wastewater (e.g., Blankenberg et al, 2008 ). Further, in a full-scale SAT with more frequent alteration of wet and dry periods ( Sharma and Kennedy, 2017 ), additional nitrification in the vadose zone, together with dilution when the recharged water reaches the aquifer, will contribute to lower ammonium levels in the aquifer than measured in our pilot system ( Sopilniak et al, 2017 ).…”

Global water supplies are threatened by climate changes and the expansion of urban areas, which have led to an increasing interest in nature-based solutions for water reuse and reclamation. Reclaimed water is a possible resource for recharging aquifers, and the addition of an organic reactive barrier has been proposed to improve the removal of pollutants. There has been a large focus on organic pollutants, but less is known about multifunctional barriers, that is, how barriers also remove nutrients that threaten groundwater ecosystems. Herein, we investigated how compost- and woodchip-based barriers affect nitrogen (N) removal in a pilot soil aquifer treatment facility designed for removing nutrients and recalcitrant compounds by investigating the composition of microbial communities and their capacity for N transformations. Secondary-treated, ammonium-rich wastewater was infiltrated through the barriers, and the changes in the concentration of ammonium, nitrate, and dissolved organic carbon (DOC) were measured after passage through the barrier during 1 year of operation. The development and composition of the microbial community in the barriers were examined, and potential N-transforming processes in the barriers were quantified by determining the abundance of key functional genes using quantitative PCR. Only one barrier, based on compost, significantly decreased the ammonium concentration in the infiltrated water. However, the reduction of reactive N in the barriers was moderate (between 21 and 37%), and there were no differences between the barrier types. All the barriers were after 1 year dominated by members of Alphaproteobacteria, Gammaproteobacteria, and Actinobacteria, although the community composition differed between the barriers. Bacterial classes belonging to the phylum Chloroflexi showed an increased relative abundance in the compost-based barriers. In contrast to the increased genetic potential for nitrification in the compost-based barriers, the woodchip-based barrier demonstrated higher genetic potentials for denitrification, nitrous oxide reduction, and dissimilatory reduction of nitrate to ammonium. The barriers have previously been shown to display a high capacity to degrade recalcitrant pollutants, but in this study, we show that most barriers performed poorly in terms of N removal and those based on compost also leaked DOC, highlighting the difficulties in designing barriers that satisfactorily meet several purposes.

“…However, because most treatment procedures include the use of chemicals and utilities, the expense of cleansing water bodies is rising. In order to solve this problem, low-cost, energy-efficient alternative home WW treatment technology is required; reed bed systems have recently received attention as a potential natural remedy [3]. In literature, researchers tried to treat WWs in Erbil City.…”

Domestic wastewater, if not correctly disposed of, is a cause of pollution for water-based bodies. The reed bed system is a sort of phytoremediation method used to remove toxins from the environment. This system has a high potential for application in the treatment of household wastewater (WW) because it has good performance as a whole, low operating and maintenance costs, and is not harmful to the environment. This research aimed to study characteristics variation of Grdarasha area WW (located in the left side of Erbil-Kirkuk main road) before and after reed beds. The reed bed system was proven to have a good efficiency in removing Chemical Oxygen Demand (COD) (15. 91-71. 07) %, Total Solid (TS) (8.33-50) %, Total volatile Solid (TVS) (18.8-50) %, and chloride (2.5 – 82.98%). In furtherance of transferring oxygen from the environment, the interplay between pollutant-plants-medium-microbes is critical in pollutant removal utilizing the reed bed technique.

“…The Range finding test is one of the steps that must be done before conducting the phytotoxicity test. This is a preliminary test to determine the concentration of contaminants at which plant species can survive in leachate-contaminated media or leachate treatment as the first step of a phytotoxicity study [ 7 , 8 , 28 ].…”
