Oxygen-Enrichment
Oxyplus works with a comparatively low
pressure difference (max. 0.1 bar). Oxy-
gen-poor water is drawn in and mixed
intensively with the pure oxygen which
has been introduced. An increase in the
surface area of the medium is obtained
by mixing and oxygen is taken up. By this
means, other gases (e. g. Nitrogen) will
also be driven out. These gases escape
through the ventilation pipe of the appa-
ratus with a minimal amount of oxygen.
Water supported by Oxyplus can be en
riched by 4-10 mg/ltr.
