Anaerobic degradation - Black water - Grey water - Micropollutant removal - Pharmaceuticals - UASB reactor

Removal of 14 pharmaceuticals and 3 of their transformation products was studied in a full-scale source separated sanitation system with separate collection and treatment of black water and grey water. Black water is treated in an up-flow anaerobic sludge blanket (UASB) reactor followed by oxygen-limited autotrophic nitrification-denitrification in a rotating biological contactor and struvite precipitation. Grey water is treated in an aerobic activated sludge process. Concentration of 10 pharmaceuticals and 2 transformation products in black water ranged between low μg/l to low mg/l. Additionally, 5 pharmaceuticals were also present in grey water in low μg/l range. Pharmaceutical influent loads were distributed over two streams, i.e. diclofenac was present for 70% in grey water, while the other compounds were predominantly associated to black water. Removal in the UASB reactor fed with black water exceeded 70% for 9 pharmaceuticals out of the 12 detected, with only two pharmaceuticals removed by sorption to sludge. Ibuprofen and the transformation product of naproxen, desmethylnaproxen, were removed in the rotating biological contactor. In contrast, only paracetamol removal exceeded 90% in the grey water treatment system while removal of other 7 pharmaceuticals was below 40% or even negative. The efficiency of pharmaceutical removal in the source separated sanitation system was compared with removal in the conventional sewage treatment plants. Furthermore, effluent concentrations of black water and grey water treatment systems were compared with predicted no-effect concentrations to assess toxicity of the effluent. Concentrations of diclofenac, ibuprofen and oxazepam in both effluents were higher than predicted no-effect concentrations, indicating the necessity of post-treatment. Ciprofloxacin, metoprolol and propranolol were found in UASB sludge in μg/g range, while pharmaceutical concentrations in struvite did not exceed the detection limits.

De verwijdering van organische stof alsook van stikstof en fosfor wordt in RWZI vaak bewerkstelligd middels een anaëroob-anoxisch-aëroob (A2/O) proces. Met behulp van het A2/O proces kunnen oppervlakte-actieve stoffen al in het anaërobe dan wel anoxische compartiment afgebroken worden. In dit proefschrift wordt de isolatie van Pseudomonas stutzeri stam SN1 en Pseudomonas nitroreducens stam SN2 uit actief slib van een RWZI met een A2/O proces beschreven.

On the island Bonaire, eutrophication is a point of serious concern, affecting the coral reefs in the marine park. Eutrophication can cause altered balance of the reef ecosystem because algae shall outcompete corals, eventually leading to a disturbed composition of the reef. The reef of Bonaire faces nutrient input by various sources, of which enriched groundwater outflow from land to the reef is considered to be a substantial source. Groundwater is enriched with nutrients due to the e.g. leaking septic tanks. In order to reduce the input of nutrients on the reef via sewage water, a water treatment plant is being built on Bonaire.
Explorative research on innovative nitrogen recovery

afvalwaterbehandeling - rioolwaterzuivering - zuiveringsinstallaties - stikstof - terugwinning - stikstofmeststoffen - stikstofkringloop - waste water treatment - sewage treatment - purification plants - nitrogen - recovery - nitrogen fertilizers - nitrogen cycle
This report comprises the results of an explorative study on innovative nitrogen recovery from side streams of wastewater treatment plants (WWTPs) in the Netherlands. The main objective of the study was to identify promising new technologies for recovery of nitrogen which can be subsequently used as an artificial fertilizer. This shortcircuits the global nitrogen cycle and thereby reduces the environmental impact of the nitrogen cycle that has been distorted by human influence (eutrophication, greenhouse gases).
Zwavel in de rwzi: Autotrofe denitrificatie en zwavelterugwinning als zuiveringstechniek voor rwzi’s - een haalbaarheidsstudie

rioolwaterzuivering - denitrificatie - zwavel - slib - sewage treatment - denitrification - sulfur - sludges
Aanvullende nitraatverwijdering vraagt om extra CZV of een efficiënter gebruik van het beschikbare CZV. De inzet van autotrofe denitrificatie maakt dit mogelijk. Bij autotrofe denitrificatie kan zwavel als elektrondonor worden gebruikt. Voor aanvullende heterotrofe denitrificatie is het gangbaar om een externe C-bron zoals methanol te doseren. De nadelen hiervan zijn veiligheidsrisico’s en kosten. Voor zwavel gelden deze nadelen minder. Ook is zwavel, zeker wanneer een interne stroom kan worden gebruikt, duurzamer. Dit onderzoek is uitgevoerd om de zwavelstromen op een rwzi in kaart te brengen en de haalbaarheid van autotrofe denitrificatie in de rwzi te verkennen. Daarnaast is onderzocht of het zwavelgehalte in slib en daarmee de aan zwavel gerelateerde slibverwerkingskosten kunnen worden verlaagd.
