Assessing Struvite Formation Potential at Wastewater Treatment Plants
(2012-12)
Wastewater treatment plants, especially those employing secondary treatment and anaerobic sludge digestion, have historically encountered phosphate precipitates, one of the commonest being struvite, that foul and encrust ...
Sustainable Management of Animal Waste in a Rural Setting in India
(2015-08)
For centuries rural people in India have used animal waste as a source of biogas to be used for cooking purposes. The animal waste is usually shaped into cakes and dried in the open before use. However, this practice has ...
Struvite Recovery from Anaerobically Digested Dairy Manure: A Review of Application Potential and Hindrances
(Elsevier, 2016-03-15)
Anaerobically digested dairy manure is rich in ammonium, orthophosphates, and magnesium, indicating a high potential for struvite recovery. Continuous generation of large amounts of dairy manure plus increasing global ...
Performance of cementitious materials produced by incorporating surface treated multiwall carbon nanotubes and silica fume
(Elsevier, 2016-07-01)
The outstanding mechanical properties of carbon nanotubes (CNTs) highlight them as potential candidates for cementitious material reinforcement. However, their low surface friction and the Van der Waals forces of attraction ...
Phosphorus Recovery from the Wastewater Stream - Necessity and Possibilities
(Taylor & Francis, 2016)
The annual demand of phosphorus (P) for fertilizer use is more than 550,000 t in Germany. Several of the input streams like mineral fertilizer produced from phosphate rock or sewage sludge are problematic due to contamination ...
Designing constructed wetlands for reclamation of pretreated wastewater and stormwater
(Springer, 2017-03)
Wastewater reclamation is getting greater attention as an alternative to conventional approaches to wastewater treatment and water supply due to increasing water stress coupled with more stringent water quality limitation ...
Evaluation of sustainable concrete produced with desalinated reject brine
(Elsevier, 2017-06)
The worldwide demand for new concrete buildings is increasing at a rapid pace to keep up with urban development. Despite the need, concrete production and its use have a number of environmental consequences. The production ...
Early detection of struvite formation in wastewater treatment plants
(2015-04)
Wastewater treatment plants operating anaerobic digestion of their sludge often have to encounter phosphate-based formations that clog piping, valves and pumps that reduce the efficiency of the treatment plant. In addition ...
Use of desalinated reject water as a source of magnesium for phosphorus recovery
(2013-06)
In this study, the formation potential of struvite has been assessed using synthetic centrate mixed with reject water of a local desalination plant. NH4H2PO4, MgCl2 .6H2O,and NH4Cl were mixed in specific concentrations to ...
