“…Treatment performance of the wetlands could be judged by the capabilities and the percentage of mass removal of contaminants and depends on the contaminant concentration in the wetland outflow It is important that the selected criteria accurately reflect the actual performance of the wetland relative to the objectives and intended uses of the wetland treatment system Dotro et al (2017). However, justification conducted on experimental results obtained from a sub-surface flow constructed wetland showed that the first few years of the constructed wetland performance is related to the initial operating stage Awad and Saleh (2001).…”

Constructed wetlands are wastewater treatment systems composed of one or more treatment cells in a building designed and constructed to provide wastewater treatment. Constructed wetlands are classified into two types: free water surface (FWS) wetlands (also known as surface flow wetlands) closely resemble natural wetlands in appearance because they contain aquatic plants that are rooted in a soil layer on the bottom of the wetland and water flows through the leaves and stems of plants. Subsurface flow wetlands (SSF) or known as a vegetated submerged bed (VSB) systems do not resemble natural wetlands because they have no standing water. They contain a bed of media (such as crushed rock, small stones, gravel, sand, or soil) that has been planted with aquatic plants. When properly designed and operated, wastewater stays beneath the surface of the media, flows in contact with the roots and rhizomes of the plants, and is not visible or available to wildlife. Constructed wetlands are an appropriate technology for areas where inexpensive land is generally available and skilled labor is less available. In this paper, a comprehensive review covered types, characteristics, design variation and considerations, limitations, and the advantages and disadvantages of constructed wetlands.

“…This produces a stronger flux pinning than the phases with two Tl-O sheets [2]. These characteristics lead to high critical current densities J c , which make Tl-1223 a potentially valuable material for the production of superconducting wires, tapes and thin-film applications [3]. Since the superconducting properties of Tl-1223 depends, sensitively, on the preparation conditions such as initial composition, heat treatment and time of preparation [4], the superconducting transition temperature T c varies from 114 to 122 K [5].…”
