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 chemicals used for treating for H2S in the oil and gas industry can sometimes be just as hazardous as the H2S itself. MIOX wants to eliminate these hazardous chemicals and let oil & gas companies create their own safe chemistry on-demand as they need it. Whether it is high volume treatment, or low volume treatments in the middle of nowhere with no resources, we have a solution for your need.
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.
Hydrogen Sulfide is lethal if released. Macrotek is a leader in developing advanced technologies for optimum removal and treatment. Our experience includes many installations using caustic, oxidizing reagents, catalytic and forced oxidation combination, and biofilters. Each application is unique and requires custom solutions.
Basis of Control with Hydrogen Peroxide
Hydrogen peroxide may be used to correct a serious filamentous bulking situation or, preferably, to prevent one from occurring until adjustments can be made to remove the cause. When applied to the return activated sludge, hydrogen peroxide supplies dissolved oxygen which helps restore the microbial activity necessary for effective operation, while selectively oxidizing the filaments which retard settling. The effective dose of hydrogen peroxide is a function of time and...
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...

PLAZKAT Aero units are used to neutralize bad smells from waste treatment facilities, caused by the presence of sulfur and nitrogen compounds - hydrogen sulfide, mercaptans, and ammonia. Urban waste treatment facilities, local waste treatment systems in factories, pumping stations in waste water treatment systems are characterized by a strong smell of sulfur and nitric compounds.
MIOX is the lowest cost supplier of chlorine for disinfection and oxidation of wastewater prior to discharge. Mixed Oxidant Solution (MOS) chemistry is more effective at biofilm control, Biochemical and Chemical oxygen demand removal (BOD/COD), breakpoint chlorination of ammonia and hydrogen sulfide (H2S) removal.
Custom water and wastewater engineering, consulting and process design services to prevent air, land, water and environmental pollution. We rework systems as processes change and troubleshoot where necessary to bring systems into compliance.

Treating the water being injected for disposal is not always considered by operators. This is likely costing you money in the long run. Removing iron, heavy metals, and treating out ammonia is a benefit to treating with MIOX’s mixed oxidant solution. While these are benefits of the technology, the most important is the elimination of bacteria which can cause Hydrogen Sulfide (H2S), corrosion pitting, poor injectivity and other problems, resulting in great well workover frequency. Treating injection wells...
The growing demand placed on the world’s water, in combination with more stringent water quality regulations, have placed unprecedented demands to provide safe, reliable and aesthetically pleasing drinking water. Air stripping is an effective way of removing volatile organic chemicals (VOCs) from contaminated water and is commonly used for this application. Air stripping systems mix air with a water supply with the goal to generate the largest possible air-water contact area so that VOCs and dissolved...
