Le défi
Struvite precipitation (ammonium magnesium phosphate, formula NH4MgPO4.6H2O) accumulates in heat exchangers and pipes during wastewater treatment. The buildup causes two issues: difficulty maintaining target temperatures, leading to higher energy consumption and reduced methane extraction efficiency; and pipe diameter reduction, limiting wastewater flow and requiring frequent cleaning or equipment replacement. Kranj has 40,000 citizens and is Slovenia's third-largest city. The treatment plant uses stainless steel pipes and heats sludge to 37 C to extract methane for electricity generation.
La solution Merus
Installation of a Merus Ring device to prevent struvite crystallization and buildup in the system.
Résultats
→Per the customer: After installing the Merus Ring, we don't need to replace the pipes anymore. Only effortless periodical cleaning of the pipes and heat exchanger is needed. This resulted in reduced maintenance costs and improved process efficiency.
