The performance of the industrial point-source water pollution abatement program in the U.S. Clean Water Act is examined. I begin with a brief description of the statute and then turn to a description of the process used to develop the rules that govern effluent discharges. This is followed by a discussion of the outcomes resulting from efforts to apply these rules to industrial pollutant sourc...

the treatment facility of albourz industrial city was established in 1999 at the southeast of albourz mountain with an area of 200,000 square meters. currently, 40,000 cubic meters of industrial wastes are treated daily utilizing biological method of activated sludge up to the second phase without chlorination in this treatment facility. then, the discharged wastes are directed toward the lower...

the increase in water demand and its services due to population growth and the raising of the standards of living, health, and hygiene along with the limitation of water resources, droughts, and climate change has attracted water specialists and planners to explore the use of unconventional water resources, such as sewage and saline waters. moreover, industrial and rural wastewater disposal and...

abstract background: heavy metals in industrial wastewater especially chromium (vi) are considered as the main environmental pollutants. methods: electrochemical cell made of plexiglass with a volume of 1.95 lit was used. iron and graphite electrodes, electricity conductor, each with dimensions of 0.1×3×10 cm (width×length×height) were designed and built. tests were carried out in various condi...

Many contaminants of interest in water and wastewater are particles, or are made into particles for removal. Typical municipal wastewater treatment plants include both primary and secondary sedimentation, and those with tertiary treatment likely have granular media filtration. Typical drinking water plants using surface water supplies have flocculation, gravity separation (sedimentation or flot...

GOAL, SCOPE AND BACKGROUND One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle waste water into high quality water. It seems timely to discuss alternative water remediation technologies that are fi...

use of microorganisms for removing mercury is an effective technology for the treatment of industrial wastewaters and can become an effective tool for the remediation of man-impacted coastal ecosystems with this metal. in this study, seven types of mercury resistant bacteria were separated from industrial waste and minimum inhibitory concentration (mic), were determined for these bacteria. resu...
