There are several contaminants in wastewater, with organic pollutants playing the major role. Many kinds of organic compounds, such as PCBs, pesticides, herbicides, phenols, polycylic aromatic hydrocarbons (PAHs), aliphatic and hetercyclic compounds are included in the wastewater, and industrial and agricultural production as well as the people living could be the source of organic wastewater e...

High residual oil content in antibiotic production waste mother liquor makes solid–liquid separation of fermentation residue and wastewater difficult. A yeast-based pretreatment process was established for the removal of oil and promotion of solid–liquid separation in antibiotic production wastewater treatment systems. Six yeast strains acquired from different sources were inoculated into seque...

In this study, in the removal of macro (P, S, Na, K, Ca, Mg) and micro (Sb, Ba, Co, Cu, Fe, Pb, Mn, Hg, Mo, Se, Ag, Zn) elements in the effluent of Elazig Wastewater Treatment Plant, the efficiency of Lemna minor L. and Lemna gibba L. has been studied comparatively. For this aim, fronds of these plants have been adapted to the effluent of the treatment plant that feeds pilot scale reactors. The...

sludge production is an avoidable problem arising from the treatment of wastewater. the sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. on the other hand, this sludge has benefits for plants and soils. thereupon, land application of sludge has received...

Effluent Treatment Plants (ETPs) are considered as one of the viable solution for small to medium enterprises effective wastewater treatment. An Plant (ETP) is an integral part production processes with relevance wastewater, pollutants their respective limit values that have be reduced. In addition, ETP also facilitates in reduction number discharge points industrial estate better enforcement b...

The rapidly increasing production of engineered nanoparticles has created a demand for particle removal from industrial and communal wastewater streams. Efficient removal is particularly important in view of increasing long-term persistence and evidence for considerable ecotoxicity of specific nanoparticles. The present work investigates the use of a model wastewater treatment plant for removal...

Collection and reuse of wastewater and sewage in agriculture, natural resources and green environment is one way to conserve water resources and environmental. The aim of this study were to investigate the effects of wastewater Sirjan golgohar industrial on the characteristics of cultivated soils in several species of pasture trees. This study was performed at the Sirjan city which is located i...

Laboratory-scale experiments were performed to develop a procedure for biological treatment of recalcitrant anaerobic industrial effluent (from ethanol and citric acid production) using first the microalga Chlorella vulgaris followed by the macrophyte Lemna minuscula. This recalcitrant dark-colored wastewater, containing high levels of organic matter and low pH, prevents the growth of microalga...

The selection of optimum high strength wastewater treatment process is complicated. Be familiar with wastewater treatment methods is not enough to design a plant. In this research, five alternative wastewater treatment methods (upflow anaerobic sludge blanket (UASB) + membrane bioreactor (MBR), UASB + Extended aeration (EA), Anaerobic baffled reactor (ABR), anaerobic lagoon (ANL) + aerated lago...

Nanofiltration (NF) has become a widely accepted process not only for producing drinking water but also for recovering wastewater in industrial processes or removing pollutants from industrial wastewater effluent. In the textile industry, the treatment of various dye baths with NF at room temperature have already been studied and was found feasible at lab-scale and pilot scale. The aim of this ...
