Deuterium oxide

Can any one say its advantage as well as disadvantage of Deutium oxide… How it can be remove from processing

Normal.water contains up to 150 ppm of Deuterium oxide and it does not have any effect on food processing…Why would you want to remove it when it does not pose any harm.?
FYI heavy water or water enriched with D2O is non toxic but due to the:heaviness" of the hydrogen isotope it can have a slowing effect on the assimilation of water in the cellular structure. So in long term use it is not beneficial physiologically…

Agreed, It impact only in case long term expose, it may slow down our biochemical reaction otherwise no radioactive impact. Still if you want to control, you can change your processing water with low Deutirium oxide water or blend of both heavy and lighter.
