Assessment of tertiary reed beds in chemically-dosed wastewater treatment plants for phosphorus removal [PDF]
, 2013 Eutrophication is one of the problems affecting the environmental quality standards of fresh waters. Phosphorus (P) is considered a main nutrient contributing to this. In the UK, the Water Industry is responsible for c.

Phosphorus removal in passive treatment technologies for tertiary wastewater treatment [PDF]
, 2014 The treatment of phosphorus at small sewage works requires alternative approaches to the traditional chemical precipitation and biological removal pathways, as such approaches do not align well to the requirements at such a scale in relation to the use

Influence of the hyporheic zone on the phosphorus dynamics of a large gravel-bed river, Garonne River, France [PDF]
, 2009 Phosphorus (P) concentrations in sediments and in surface and interstitial water from three gravel bars in a large river (Garonne River, southern France) were measured daily, downstream of a wastewater treatment plant for a city of 740 000 inhabitants ...

Total phosphorus and phosphorus forms change in sediments along the Tone River
Frontiers in Earth Science, 2023 Phosphorus (P) is an essential element for the metabolism, growth, and development of living organisms, and it often limits primary production in freshwater ecosystems. During flood events, rivers can transport considerable amounts of particulate organic

Phosphorus chemistry and bacterial community composition interact in brackish sediments receiving agricultural discharges. [PDF]
PLoS ONE, 2011 BACKGROUND: External nutrient discharges have caused eutrophication in many estuaries and coastal seas such as the Baltic Sea. The sedimented nutrients can affect bacterial communities which, in turn, are widely believed to contribute to release of ...

Phosphorus recovery from wastewater by struvite crystallization: A review [PDF]
, 2009 The present review provides an understanding of principles of struvite crystallization and examines the techniques and processes experimented to date by researchers at laboratory, pilot, and full-scale to maximize phosphorus removal and reuse as struvite

Forms of organic phosphorus in wetland soils [PDF]
Biogeosciences, 2014 Phosphorus (P) cycling in freshwater wetlands is dominated by biological mechanisms, yet there has been no comprehensive examination of the forms of biogenic P (i.e., forms derived from biological activity) in wetland soils.
