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.Find out more
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.

IER works cooperatively with our parent company, Calix Ltd. (www.calix.global), along with our customers, engineers, and partners worldwide, to extract the best understanding of every industrial situation in order to create a positive sustainable difference for the long-term.
Because there is only one Earth.
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.
