Hydrogen sulfide sequestration

Unlike other agents, which can be costly, potentially hazardous, and targeted at a single issue, AMALGAM offers a safe and cost-effective strategy for managing H2S.

  • Excessive odor in sewage network, causing odor complaints ?
  • Heavy build-up of Fogs layers in the network causing severe corrosion ?
  • Excess usage of chemicals like lime and alum, & iron salts leading to high maintenance costs ?
  • Frequent need for vacuum truck cleaning leading to an increase in maintenance costs ?

Hydrogen sulfide (H2S) gas is produced in wastewater collection systems with a distinctive and unpleasant rotten egg smell causing frequent odor complaints. 

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-60 for H2S sequestration

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.

Magnesium hydroxide is a buffered alkali

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 and no pH excursions that are harmful to bacterial growth.

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.

COST-EFFECTIVE WASTEWATER TREATMENT SOLUTION

SAFER FOR PEOPLE   •   BETTER FOR EARTH

Hazardous work environments

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.

Accelerated corrosion of assets

When dissolved in water, H2S is converted to sulfuric acid, which can corrode the internal walls of sewers, manholes, pump stations and other concrete and steel structures.

SUPPORTING WATERAID

Because we truly care about sanitation

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.
