dc.description.abstractHigh calcium concentrations are problematic, because they lead to clogging of pipelines, boilers and heat exchangers through scaling, or malfunctioning of aerobic and anaerobic reactors. Urea hydrolysis provides simultaneously a pH and CO2 increase, both of which are responsible of CaCO3 production. This study was carried out to determine urea concentrations between 5 and 20 mM on ureolytic mixed culture treating synthetic wastewater. The optimum urea concentration was found as 15 mM for effective calcium removal. This work showed the feasibility of urea-based microbial carbonate precipitation as an alternative Ca2+ removal technology. (C) 2012 The Korean Society of Industrial and Engineering Chemistry.
