Nutrient removal from UASB effluent in agro-industries [PDF]
Phosphorus and nitrogen are important elements, making a major contribution to agricultural and industrial development, but their release to natural water bodies are the main causes of eutrophication. Anaerobic digestion yields effluents rich in ammonium

Anaerobic Treatment of Concentrated Black Water in UASB Reactor at a Short HRT [PDF]
This research describes the feasibility of applying a UASB reactor for the treatment of concentrated black (toilet) water at 25 °C. On average 78% of the influent load of COD at an HRT of 8.7 days was removed. Produced methane can be converted to 56 MJ/p/

Simultaneous removal of phosphorus and nitrogen from sewage using a novel combo system of fluidized bed reactor-membrane bioreactor (FBR-MBR) [PDF]
A FBR-MBR combo system was designed as a novel approach for simultaneous phosphorus and nitrogen removal from sewage. The combo system was evaluated more than 7months under variable pH (7.5-9.5), hydraulic retention times (HRT=2-10h), intermittent ...

The use of wastewater-derived struvite (MgNH4PO4·6H2O) as a lower water solubility alternative to highly water-soluble phosphorus (P) fertilizers such as monoammonium phosphate (MAP) has been widely hypothesized to reduce fertilizer nitrogen (N) and ...

Effects of struvite application on soil and plants: a short‐term field study [PDF]
The soil P concentration commonly declines over time by organic management, if the farm does not acquire enough fertilisers or other inputs containing P from outside. An interesting source to supply farms with P is struvite (magnesium‐ammonium phosphate).

Struvite crystallization [PDF]
The present invention provides a method and apparatus for removing phosphorus from phosphorus containing waste. In one embodiment, the method is preferably carried out by contacting the phosphorus containing waste with a non-cellular membrane and ...
