Pitfalls to steer clear of and best practices to follow to avoid costly missteps and regulatory headaches In the realm of waste management and biogas production through anaerobic digestion, understanding the unique characteristics and requirements of each project is crucial. Missteps can lead to inefficiencies, higher costs, and compliance issues. Here we explore common pitfalls and provide ...
To optimise sludge dewatering and phosphate removal, a full-scale test has been executed since August 2015 using temporary equipment. ...
A full-scale struvite crystallization system was operated for the treatment of the centrate obtained from the sludge anaerobic digester in a municipal wastewater treatment plant. ...
In this work, effects of magnesium (Mg) dose (in terms of Mg:P ratio) on P recovery efficiency and pharmaceutical amounts contained in struvite were investigated. Batch-scale experiments of synthetic and human urines revealed that struvite precipitation formed more X-shaped crystals with an increased molar ratio of Mg:P, while the amount of ...

The lab report indicated that the scale deposits were composed of magnesium, ammonia and phosphate, which is struvite. The plant acquired several products from different suppliers and ran a bench study to determine which product would dissolve the struvite and not damage the belt cloth They took five (5) one gram samples of the ...
Five month evaluation of Hydropath technology’s ability to treat magnesium ammonium phosphate hexahydrate (Struvite, NH₄MgPO₄•6H₂O) scale and to enhance flocculation resulting in reduced polymer usage Location: City of Orlando Wastewater Treatment Plant. ...
Named after Henrich Christian Gottfried Von Struve, who discovered the magnesium ammonium phosphate crystals in medieval sewer systems in Hamburg in 1845, struvite is a major problem for waste water treatment plants. The hard, crystalline deposit forms scale on lines and belts, in centrifuges and pumps. ...
A regional wastewater treatment plant in Sonoma County was experiencing problems with struvite on their screw presses and vivianite on their heat exchangers.The plant maintenance staff was forced to shut down the dewatering process every three (3) weeks to clean because of struvite deposits on the screen of the screw press. They also noticed that they were having ...
CAFOs (Confined Animal Feeding Operations) face struvite in their manure holding ponds and manure lagoons, as well as their recirculation systems. ...
