Towards mainstream anammox: lessons learned from pilot-scale research at WWTP Dokhaven

The aim of this research was to study the biological feasibility of the Partial Nitritation/Anammox (PN/A) technology to remove nitrogen from municipal mainstream wastewaters. During stable process operations at summer temperatures (23.2 ± 1.3°C), the total nitrogen removal rate was 0.223 ± 0.029 kg N (m³d)⁻¹ while at...

Cenirelta: Cost Effective NItrogen REmoval from wastewater with Low Temperature Anammox: Demonstratieproject anammox in de hoofdstroom op RWZI Dokhaven

De doelstelling van het CENIRELTA project was aan te tonen dat Anammox in de hoofdstroom van een rwzi een effectieve, robuuste, kosten-efficiënte en duurzame technologie biedt voor de verwijdering van stikstof uit huishoudelijk afvalwater. De effectiviteit en robuustheid van het hoofdstroom Anammox proces zijn beproefd op rwzi Dokhaven in...

Filtration Characterization Method as Tool to Assess Membrane Bioreactor Sludge Filterability—The Delft Experience

Prevention and removal of fouling is often the most energy intensive process in Membrane Bioreactors (MBRs), responsible for 40% to 50% of the total specific energy consumed in submerged MBRs. In the past decade, methods were developed to quantify and qualify fouling, aiming to support optimization in MBR operation. Therefore, there is a need...

The Delft Filtration Characterisation method: Assessing membrane bioreactor activated sludge filterability

Clean water is becoming a scarce resource. As a consequence reclaimed wastewater can be an attractive alternative to replace existing water resources for non-potable reuse options. In order to achieve this goal advanced treatment technologies are required. An example of such technology is the membrane bioreactor (MBR) process. In the MBR process...
