Treatment of table olive processing wastewaters using novel photomodified ultrafiltration membranes as first step for recovering phenolic compounds

Advanced Treatment of Meat Processing Wastewaters Using Microalgae

Introduction: Effluents of Meat processing are one of the untreated wastewaters containing high volumes of polluted components even after the primary and secondary treatments. The high cost of using the advanced treatment methods of the wastewaters has led the industry owners to release them in the nature without effective removal of nitrogen and phosphorus. In this study, an economic advanced ...

Preparation of blend hydrophilic PSF-SPEEK ultrafiltration membranes for oily wastewater treatment

Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...

Novel Charged Ultrafiltration Membranes for Protein Separations

Although there have been no significant studies of the effects of different coupling chemistries, spacer arm length, or the nature of the functional group on the performance of ultrafiltration membranes, there is an extensive literature on these parameters in the field of chromatography. An optimal spacer arm ensures that the functional groups are placed a suitable distance from the surface of ...

Assessment of the antioxidant and antibacterial activities of different olive processing wastewaters

Olive processing wastewaters (OPW), namely olive mill wastewater (OMW) and table-olive wastewaters (TOW) were evaluated for their antibacterial activity against five Gram-positive and two Gram-negative bacteria using the standard disc diffusion and thin layer chromatography (TLC)-bioautography assays. Disc diffusion screening and bioautography of OMW were compared to the phenolic extracts of ta...
