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

New insights into the early Bajocian (Middle Jurassic) carbon cycle perturbation
Sedimentologika, 2023 Mesozoic strata record numerous negative and positive carbon isotope excursions (CIEs). The Middle Jurassic records a negative ~0.5 ‰ CIE at the Aalenian-Bajocian boundary followed by a positive ~1.5 ‰ CIE covering the entire early Bajocian.

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.
