Impact of strip gas composition on side stream ammonia stripping, a technology aiming at the reduction high levels in anaerobic reactors, was investigated. Evaluation effect oxygen contact during air stripping showed distinct, though lower than perceived, inhibition microflora. To circumvent, feasibility and possible constraints biogas flue as alternatives were studied. Experiments, with bicarbonate model solution digestate, conducted. It demonstrated that performance is negatively...
Manure represents an exquisite mining opportunity for nutrient recovery (nitrogen and phosphorus), their reuse as renewable fertilisers. The ManureEcoMine proposes integrated approach of technologies, operated in a pilot-scale installation treating swine manure (83.7%) Ecofrit® (16.3%), mix vegetable residues. Thermophilic anaerobic digestion was performed 150 days, the final organic loading rate 4.6 kgCOD m−3 d−1, with biogas production 1.4 Nm3 d−1. digester coupled to ammonia side-stream...
A new approach to perform partial nitritation–anammox in a single tank was investigated. The incorporated mesh (opening size 1.0 × 1.2 mm) as permeable barrier create two distinct reaction zones (aerated and anoxic). study reports on the operation optimization of 13 L laboratory scale reactor treat sludge reject water with an NH4-N concentration ~750 mg·L−1. Performance throughout 250 days at increasing nitrogen loading rates is presented. maximum rate applied 1.5 kg NH4-N·m−3·d−1 hydraulic...
Abstract It is widely accepted that partial nitrification by ANAMMOX has the potential to become one of key processes in wastewater treatment. However, large greenhouse gas emissions have been panobserved many cases. A novel mesh separated reactor, developed allow continuous operation deammonification at smaller scale without external biomass selection, was compared a conventional single-chamber sequencing batch reactor (SBR), where both were equally-sized pilot-scale reactors. The consisted...
In urban humanitarian-aid operations, safe treatment of fecal sludge is highly important. While currently field-deployable fecal-sludge plants are being developed, field-ready analytical equipment for process-control and public health monitoring missing. Within the Microbial Sludge Quality project, a field laboratory was developed. A minimum set parameters considered processes developed through literature research. The methods were tested on their applicability and, if necessary, modified....
