Abstract:Variations in phosphorus (P) speciation were compared for two types of pilot scale wetlands: a blast furnace slag-based constructed wetland (SCW), and a gravel-based constructed wetland (GCW). Synthetic secondary effluent was used as the influent of the wetlands, which contained 1.1 mg/L P with more than 95% present as soluble reactive P (SRP). However, dissolved organic phosphorus (DOP) and particulate phosphorus (PP) emerged in the water along both wetlands. The levels of these three P species varied between… Show more
“…According to Fig. 2C, the Oc-P content was highest for seven forms of P. Our results agreed with Shan et al (2009), who found that the Oc-P was the most abundant form of P in the sediment. Ca-P content was shown in Fig.…”

“…Some industrial waste materials, including fly ash, have already been tested as support matrix components of CWS [242,[274][275][276][277][278][279][280], although the target of the treatment systems have been mostly nutrients and other inorganic pollutants such as metals. Still, some of these support materials seemed adequate for the development of the biotic CWS components.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
