Aerobic And Anaerobic Conditions

The analysis of processes intensification of biological wastewater treatment in aerobic and anaerobic conditions using a new generation of bio-stimulants was performed. The humic preparation and synthetic Melaphen influence was investigated on the biocenosis sludge. The humic preparation and Melaphen provided different effects on the growth of microorganisms in the sludge. It was shown that effect depends on concentration of bio-stimulants and stage of microorganisms growth. The concentrations 10-1 and 10-3 g /dm3 for humic preparation and Melaphen respectively were intensified microorganisms growth. The results show that using humic preparation 10-3 g /dm3 and Melaphen - 10-6 mg/dm3 the most effective for the treatment of wastewater in aerobic conditions, but using humic preparation 10-1 g/dm3 and Melaphen - 10-6 mg/dm3 in anaerobic conditions.

Abstract The key driver for anaerobic membrane bioreactors (AnMBRs) for municipal wastewater treatment is enabling the transition to energy neutral wastewater treatment. However, municipal wastewater delivers a comparatively constrained methane yield, which means energy conservation must be prioritised to achieve the proposed energy neutral ambition. A critical focus on membrane fouling is therefore warranted, as membrane operation represents the primary energy demand in MBRs. This review seeks to quantify the characteristics of the prevailing AnMBR biological suspension and to ascertain whether knowledge transfer exists between fouling characteristics in aerobic and anaerobic MBRs for municipal applications. Analysis of literature data revealed that the level of extractable extracellular polymeric substrate is slightly higher in aerobic MBRs than in anaerobic MBRs. However, AnMBR comprises considerably higher soluble microbial product concentrations, which have been widely reported to increase fouling propensity in aerobic systems. More distinct is the difference in the colloidal and fine solids fraction (between 1 and 10–15 μm), which is likely to dominate fouling in anaerobic systems and limit knowledge transfer from aerobic MBRs. Literature data on energy production was compared to that employed for membrane operation, and evidences that despite the challenging character of the particle matrix, energy neutral operation is achievable for AnMBR applied to municipal wastewater treatment.
