Odor & corrosion control

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 odor.

Hydrogen sulfide (H2S) gas is produced in wastewater, causing odor and corrosion issues in sewer systems

Hydrogen sulfide is present due to anaerobic activity, which favors sulfate reducing bacteria (SRB) and results in the generation of a poisonous rotten egg gas called H2S. AMALGAM effectively locks up H2S to prevent release as a gas that produces odor and facilitates corrosion. AMALGAM is safe to handle and cost effective with many benefits that reduce treatment costs at the Wastewater Treatment Plant (WWTP).

AMALGAM for odor and corrosion control

AMALGAM-60 (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 for hydrogen sulfide gas (H2S) control in sewers.

Key Benefits

Attractive cost savings

while AMALGAM-60 is typically more expensive then 50% NaOH on a “price per unit” basis, it is significantly less expensive in use – because every 1.0 lb of 50% NaOH can be replaced by 0.6 lbs of 60% Mg(OH)2 to provide the same number of moles of hydroxide (OH) for pH neutralization.

Buffering

the strong buffering characteristics of AMALGAM are key in its success to lock in the pH to hold H2S in solution in the treated sewer lines, eliminating odor and gas-phase corrosion of H2S; with benefits at the treatment plant.

Earth-friendly

magnesium is a macronutrient, the core element of chlorophyll (makes everything green!) – while sodium is a salinity hazard.

Safer

non-hazardous for employees to handle, corrosion free, spill is not reportable.

H2S is highly toxic…

At just 0.0047 ppm, your customers will start detecting the characteristic ‘rotten egg’ smell of H2S.

Better neutralization, less costs

Made with high surface area MgO (200m2 /gm), AMALGAM provides excellent neutralisation speed and produces less sludge, making it a much more stable product, which stays as a suspension longer compared to other Magnesium Hydroxide slurries.

  • Low viscosity – flows easily in most dosing systems
  • Higher neutralization potential – better cost and usage efficiency
  • Reduced sludge – easier disposal (less costs)
  • Safe to handle / non hazardous (corrosion free)
  • Buffers at pH 9 if overdosed – better stability

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.
