摘要: In this study, the feasibility of waste lime as a potential cation source in phosphate crystallization process was investigated using laboratory scale upflow reactors, adopting sequencing batch type configuration. This research focused on its successful application novel sludge treatment process, which is comprised high performance fermenter (operating conditions: 55°C and pH 9) followed by reactor. struvite precipitation test synthetic wastewater, considerable nutrient removal (about 60%) form ammonia observed within 0.5 - 1 hr retention time, only small amounts (< 5%) stripping occurred naturally due to alkaline (pH characteristic feed substrate. By replacing wastewater with fermentation effluent, optimal dosage magnesium salt for 0.86 g Mg g−1 P, similar mass ratio struvite. The 0.3 1−1, resulting 80 ...
