The need for recycling Modern microelectronics fabs are dependent upon a continuous flow of UPW for normal operations, requiring 500 cubic meters per hour or more to manufacture product. Each new fab uses 4,000 to 12,000 cubic meters per day just for wafer processing. As the industry continues to expand and develop more advanced technologies, an even greater burden is placed on limited water, s...

 Hoor al-Azim wetland, are a large and permanent wetland area located between Iran and Iraq.  By entering the flow to the wetland area, the geometry of the wetland, acts in the form of an inverted imperfect pyramid. So that by entering the water flow, the water level of wetland is simultaneous by increasing the surface. In this study by using the geometric relationships of pyramids, was acted t...

The use of drinking water for washing dishes, clothes, cars as well as bathing and watering gardens are of the important reasons for piped water high consumption in Iran. However, different lifes...

Amphitheater-headed canyons have been used as diagnostic indicators of erosion by groundwater seepage, which has important implications for landscape evolution on Earth and astrobiology on Mars.
