Deuterium- depleted (D- depleted) water is said to be a new anti-tumor veterinary medicine
for treating cats and dogs. G. Somlyai reported the biological effect of D- depleted water
which is a new possibility in cancer therapy.
The authors tried to estimate numerically the size of plants producing D- depleted water,
namely,
(1) Water distillation column process,
(2) Monothermal H2/H2O- isotopic exchange column process,
(3)Bithermal H2/H2O- isotopic exchange column process,
excluding H2 or H2O/NH3- isotopic exchange and H2O/H2S- isotopic exchange process from
a sanitary point of view of drink water.
D- depleted water, as a by product of heavy water production by means of bithermal H2/H2Oisotopic exchange process, may be considered to be the cheapest, but in this paper the authors
tried to estimate an independent and non- parasite producing D- depleted water.
As the result, the water distillation column process was found to be a favourable process for
the production of a cheaper D- depleted water.
