Product Description
Ammonia NH3,
Hydrogen Sulfide H2S
The collection and processing of sewage and industrial waste water
is often a source of unpleasant odors mainly
ammonia (NH3)
and Hydrogen sulfide (H2S).
These odors come from screening unit, sand/grit removal unit, pump
station and sludge dewatering unit.
enki’s two stage counter-flow vertical Packed Bed
Scrubber removes these odors. The first packed tower uses aqueous
sulfuric acid (H2SO4) solution to remove ammonia (NH3)
according to the below reaction:
2NH3 +
H2SO4 ➝
(NH4)2SO4
Ammonium sulfate salt [(NH4)2SO4],
is soluble and non-volatile and it is easily removed by the
blowdown.
In the second stage are used sodium hydroxide (NaOH) and sodium
hypochlorite (NaOCl) solution. NaOCl oxidizes the hydrogen sulfide.
The complete reaction is given below:
H2S
+ 4 NaOCl + 2NaOH ➝ Na2SO4 +
4NaCl + 2H2O
Na2SO4 and
NaCl are removed by the blowdown. The efficiency for removal of
NH3 and
H2S
is greater than *9%.
