Rapid acidification and inhibition by d-limonene are major challenges of biogas production from citrus waste. As limonene is a hydrophobic chemical, this challenge was encountered using hydrophilic polyvinylidine difluoride (PVDF) membranes in a biogas reactor. The more sensitive methane-producing archaea were encapsulated in the membranes, while freely suspended digesting bacteria were present...

With the current focus on water reuse projects and the role they play in the water cycle, the search for cost competitive advanced wastewater treatment technologies has never before been so important. Australia in particular has a need to develop new strategies for water management and will continue to move towards water reuse where such projects are shown to be financially viable. This paper d...

A laboratory-scale pilot plant of moving bed biofilm reactor coupled with membrane bioreactor (MBBR-MBR) was studied regard to wastewater treatment in the textile industry, and reuse feasibility treated water investigated. The comprised two connected parts: an aerobic tank filled carriers a submerged tank. MBBR-MBR system reduced hydraulic retention time 1 day, which is very promising compared ...

The objective of this study was to develop an innovative and advanced integrated “membrane oxidation” system for the treatment domestic wastewater by coupling membrane bioreactor (MBR), nanofiltration (NF) ozonation. Five contaminants were selected (acetaminophen, carbamazepin, sulfamethoxazole, tetracyclin terbutryn). MBR effluent samples have been fully characterized using conventional analys...

Phenolic compounds cause problems for conventional treatments due to their toxic and inhibitory properties. This work investigated the treatability of phenolic compounds by using two membrane-bioreactor systems, namely: activated sludge coupled with MBR (AS-MBR) and biological granular activated carbon coupled with MBR (BAC-MBR). Initially, the system was fed with phenol (500 mg/L) followed by ...

Increasing urbanization and industrialization is continuously putting a pressure on the ground fresh water resource in form of quality quantity. Therefore recycling through wastewater treatment need present hour. study efficiency 3.2MLD sewage plant (STP) based membrane bioreactor technology (MBR) located Indian Farmers Fertilizer Cooperative Limited (IFFCO) township Aonla, Bareilly, Uttar Prad...

This research investigated a membrane bioreactor (MBR) process for removing biodegradable organic matter (BOM) and trihalomethane (THM) precursors from pre-ozonated water. Bench-scale and mini-pilot-scale MBR experiments were conducted using powdered activated carbon (PAC) and acclimated biomass. Dissolved organic carbon (DOC) was removed through a combination of adsorption and biodegradation m...
