A safe, green & cost-effective alternative to caustic soda

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.

Webinar Series – Better pH & Alkalinity Control

A very informative, yet brief session from Dr Doug Kelley, one of the field leaders in pH and alkalinity control – to understand the basic chemistry that lies under the pH measurement and how alkalinity and other chemicals can affect wastewater treatment. Also learn about the differences between using caustic, lime and soda ash for pH control or  the cost benefits of using Magnesium Hydroxide products.

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.
