PRODUCED WATER

March 27, 2019

Scientists, including one of Indian origin, have developed a process to remove nearly all traces of oil in produced water.

New method to purify water used in oil refinement: 

  • Researchers at Purdue University in the US have developed a process to remove nearly all traces of oil in produced water. 

  • Method: The process uses activated charcoal foam and subjects it to solar light to produce heat and purify the water. The foam absorbs the oil contaminants from the water. 

  • Benefits of this method:
    • This is a simple, clean and inexpensive treatment process.

    • This is the first-of-its-kind method to do this purification in a single step simultaneously via a perforated foam.

    • The oil absorbed by the foam can be recovered efficiently.

    • The process could be integrated with existing disposal systems to purify a large amount of water and reduce the current stress on water grids.
