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.
ALKA-Mag+ (60% Mg(OH)2) has a higher neutralizing value per pound than any other alkaline additive. This translates into a 40% reduction in chemical usage when compared with caustic soda, while being significantly safer for operators to handle and more nutritive for the microorganisms being maintained – making it the most cost-effective option.
* In 2022, AMALGAM-60 was renamed ALKA-Mag+ – Improved stability, flowability, and reactivity from IER & Calix’s synergy.
Enquire nowThis means ALKA-Mag+ 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 ALKA-Mag+ 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.

A Letter from Doug Kelley, President of IER Hello, everyone. I am writing this message on March 20th, the last
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.
