بوی
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 99%.
Odor removal plant includes;
· Scrubber
· PP Packing media
· Circulation pump,
· Instrument,
· Chemical dosing unit
· Control Unit
