Hydrogen Peroxide as a Replacement for Sodium Hypochlorite
Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution.
H2S + NaOH → NaSH + H2O
4H2O2 + H2S → H2SO4 + 4H2O
Typical dose ratios are 5 parts H2O2 per part H2S or, when...
In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.
The presence of hydrogen sulfide in home drinking water supplies is not a health hazard, but is a common nuisance contaminant whose distinctive `rotten egg` odor makes water treatment desirable. Several treatment methods are available, and often hydrogen sulfide can be treated and removed using the same process and equipment used for iron and manganese removal.
Ozone is a highly effective method for bacteriological treatment and useful in a variety of everyday situations from removing odor to ensuring clean, high quality drinking water from the tap. But O3 is more than just effective. It is also environmentally safe, which makes it highly suitable for treating water in enormous quantities; both drinking water and industrial waste water, i.e. in industrial slaughterhouses.

Industrial and municipal waste contaminated with fat – a frequent problem for companies maintaining wastewater network infrastructure and municipal wastewater treatment facilities. We recommend the use of GREASOLUX fat dissolvent cartridges to avoid the problems of pipeline chocking, equipment damage, offensive odors, formation of filamentous bacteria, poor wastewater treatment results, poor sedimental properties of activated sludge. GREASOLUX – is a cartridge that slowly dissolves in water, enriched...
Carbon Activated Corporation supplies a complete line of high-capacity activated carbon for vapor phase and air applications such as odor control in municipal waste-water facilities, landfills and refineries, SVE (soil vapor extraction) projects and many other vapor related applications. We manufacture specialized carbon both impregnated and non-impregnated for applications such as H2S removal and the removal of any time of noxious gases.
