Introduction: Today, one of the main causes of water, soil and air pollution is undoubtedly wastewater. Among the different types of wastewaters, textile wastewater contains a large amount of hazardous and toxic pollutants such as dyes. Cleavage of azo dyes under a reduction environment produces aromatic amines (AAs) which consider more toxic than...

The illegal release of wash water from various ship parts has become a major source of pollution in the seas. These released wastes have oil, hydrocarbon, and oil derivatives. The toxic compounds in these wastes both adversely affect aquatic life and reach human beings by mixing into the food chain. Various international and regional agreements hav...
Article
Membrane bioreactors (MBR) with osmotic pressure driven membranes have significant advantages over bioreactors operated with pressure driven membranes. Since no pressure is applied to the membrane, except the concentrate circulation, osmotic membranes are less prone to fouling. Membrane fouling is an important limiting factor in MBRs, resulting in...
Article
In this study, a novel osmotic membrane was developed by polyamide (PA) coating on the tubular electrospun nanofiber (TuEN) support membrane. Water and reverse salt flux properties of the obtained membrane were investigated by applying pressure in addition to the osmotic forces. Surface characterization of the membrane was carried out by Fourier-tr...

Veterinary antibiotics are used in the dairy animal for therapeutic purposes to better absorb nutrients and treat different diseases. However, developments of resistance against veterinary antibiotics which is generally disposed into the agricultural lands have been reported as a considerable concern. Therefore, this study was conducted to determin...
Article
Nanofibers fabricated with electrospinning method have several prominent properties such as high specific surface area, high porosity and uniform pore size distribution in nanoscale or microscale. These unique features are vital for separation processes in water and wastewater treatment applications. In this study, we have developed a new type of n...
Article
Forward osmosis or osmotic membrane bioreactor (FOMBR) has attracted great attention for wastewater treatment and reuse since conceptually introduced as a process. It has been proposed to reduce the high energy consumption in the conventional MBR, has lower membrane fouling propensity, and produce higher quality water. Moreover, RO process can be u...

Hydraulic behavior of declining rate filtration (DRF) was investigated by means of pilot-scale experiments. A bank of four declining rate filters was constructed and operated. The common water level in the filters, individual filter velocities, and head losses in the filters were carefully monitored and recorded as functions of time. Many of the pr...
