this study was conducted to investigate the characteristics of input and output wastewater of the bandargaz wastewater treatment plant on the basis of the data collected during operation and the samples taken during the study period. for this purpose, three samples were taken from the outflow wastewater and 25 quality parameters were tested. also, four soil samples were taken from the soils whi...

background: olive oil wastewater  contains chemical contents and organic materials that are resistant to biodegradation.  the existence of phenolic inhibitor compounds, toxicity to microorganisms in wastewater treatment units, unpleasant odor, high biochemical oxygen demand (bod) and chemical oxygen demand (cod), high suspended solids, and compounds resistant to biodegradation in such wastewate...

Waste management studies are usually done using calibrated and verified water quality models. Ravi River located in Lahore, Pakistan is receiving untreated wastewater from number of outfalls and surface drains and thus model calibration and verification are done using the data under the prevailing conditions. The water quality objectives can only be met with wastewater treatment wherein the mod...

Currently in many cities and rural areas of Vietnam, wastewater is discharged to the environment without any treatment, which emits considerable amount of greenhouse gas (GHG), particularly methane. In this study, four GHG emission scenarios were examined, as well as the baseline scenario, in order to verify the potential of GHG reduction from domestic wastewater with adequate treatment facilit...

Ammonium removal is a key step in biological wastewater treatment and novel approaches that improve this process are in great demand. The aim of this study is to test the hypothesis that ammonium removal from wastewater can be stimulated by static magnetic fields. This was achieved by analysis of the effects of static magnetic field (SMF) on the growth and activity of Nitrosomonas europaea, a k...

Objective: More and more non-degradable substances in wastewater along change of life style, however, traditional handling agent has not met the demand of wastewater treatment, so it is very important to study for new highefficient flocculent. Method: Sifting out six microbes after testing and inoculation, and then testing for wastewater quality having three contents, this found that mix bacter...

This review presents microbial fuel cells (MFCs) that convert biochemical metabolic energy into electrical energy. Microbes can be fed with waste products rich in organic matter (domestic wastewater, lignocellulosic biomass, brewery wastewater, starch processing wastewater, landfill leachates etc.) to generate electricity. MFCs can also be used for wastewater treatment, as biosensors and produc...

The Skokomish salmon processing plant was built to provide a more efficient system for handling fish from the Indian commercial fishery on the Skokomish River. It is located on the Olympic Peninsula near the mouth of the Skokomish River about 45 miles southwest of Seattle, Washington (Figure 1). processing plant was designed in 1971, constructed in 1972, and has been in operation since December...

A simple experimental set-up was used to study the treatability aspect of phenolic wastewater. Three types of systems: i) activated sludge (A.S), ii) granular activated carbon (A.C) and iii) activated sludge plus activated carbon (A.S + A.C) were experimented under different phenol loadings (100, 200 and 300 mg/l) and different flow rates (21.6 and 43.2 l/d) with initial COD concentration 500 m...

The fermentation process in which organic material is degraded and biogas (composed of mainly methane and carbon dioxide) is produced, is referred to as anaerobic digestion. Anaerobic digestion processes occur in many places where organic material is available and redox potential is low (zero oxygen). This is typically the case in stomachs of ruminants, in marshes, sediments of lakes and ditche...
