Treated Sewage Effluent

Pilot scale investigations were carried out to examine the pollutant removal efficiency of a constructed wetland receiving secondary treated sewage effluent. Four constructed wetland cells were established, three of them planted with either Schoenoplectus validus, Juncus ingens or both species of macrophytes, and the fourth serving as an unvegetated control cell. Although there was a significant improvement in the effluent quality during the initial ten month period of monitoring, results to date have not indicated any overall trend for pollutant removal by a particular plant species. Biochemical oxygen demand and chemical oxygen demand removals averaged between 71-75% while suspended solids removals were around 85% in the macrophyte cells. Ammonia reductions were in the range 17-24% but better nitrate reductions between 65-80% were obtained. Phosphorus removal has been low (13%) in all four of the wetland cells and bore hole samples have shown no groundwater contamination with nitrogen or phosphorus from the wetland system to date.

Treated Sewage Effluent

A constructed wetland system has been developed for polishing of treated sewage effluent at Byron Bay, northern New South Wales, Australia. Nutrient removal and disinfection performance of the system has been monitored in preliminary investigations and has been found to be promising. The system, monitoring program and ongoing research program are described

This chapter looks at the infrastructure of blue (water resources) in Bahrain's built environment, as well as the efficacy of blue in keeping the country green. Beginning with a description of the Bahraini light and the colors of the sea, from technical, historical, and social perspectives, the chapter studies the water system and the politics of treated sewage effluent (TSE). Over half the water of the state is used in the irrigation of green space in Bahrain—an indication of the enormous value accorded to green. Because Bahrain is an island, the intensity of the light and the colors it animates are amplified due to the humidity generated by the surrounding sea.
