Water treatment * Water treatment - describes those industrial-scale processes used to make water more acceptable for a desired end-use. These can include use for drinking water‚ industry‚ medical and many other uses.

WATER POLLUTION INTRODUCTION Although some kinds of water pollution can occur through natural processes‚ it is mostly a result of human activities.

The water we use is taken from lakes and rivers‚ and from underground (groundwater); and after we have used it-- and contaminated it-- most of it returns to these locations. The used water of a community is called wastewater‚ or sewage. If

Water and Life on Mars Mars perhaps first caught public interest in the late 1870s‚ when Italian astronomer Giovanni Schiaparelli reported using a telescope to observe canali‚ or channels‚ on Mars. By the turn of the century‚ popular songs told of sending messages between Earth and Mars by means of huge signal mirrors. On a darker side‚ H.G. Wells’ 1898 novel The War of the Worlds portrayed an invasion of Earth by technologically superior Martians desperate for water. (1) In the early 1900s
