Hydrogen sulfide (H2S) gas typically is formed in wastewater collection systems that are conducive to creating septic conditions. Therefore, they combine with hydrogen to produce hydrogen sulfide gas, creating the "rotten egg" odor associated with septic wastewater.
AMALGAM has a higher neutralizing value per pound when compared with caustic while being significantly safer to handle than other traditional alkalis, making it a very safe
and cost competitive option for hydrogen sulfide gas (H2S) control in sewers.
This means AMALGAM-60 can hold the pH within a tight range despite acidic pH fluctuations entering the wastewater treatment process from the plant. Even if overdosed, the maximum pH that can be attained with magnesium hydroxide is 9.0. This buffering ability means better stability, no pH excursions that are harmful to bacterial growth resulting in great sulfide odor control.
The strong buffering characteristics of AMALGAM-60 are key in its success to lock in the pH to hold hydrogen sulfide in solution in the treated sewer lines, eliminating odor and gas-phase corrosion of H2S; the boost in pH and alkalinity in the collection system will also have benefits when the flow arrives at the treatment plant.
At just 0.0047 ppm, your customers will start detecting the characteristic ‘rotten egg’ smell of H2S.
Once released from the sewage (i.e. the liquid phase), H2S gas can be toxic to sewer workers, even at low concentrations.

Almost 2 billion people do not have a decent toilet or access to basic and safely managed sanitation. In many cases, faeces and urine end up untreated in the environment, contaminating it and threatening people’s health.
This is why IER supports WaterAid programs, to facilitate access to safe water, sanitation and hygiene in the world’s poorest and most marginalised communities.
