IER has products and expertise in applications such as:
In 1997, Dick Handley created Inland Environmental Resources (IER) in order to provide local manufacturing and supply of environmentally-friendly Magnesium Hydroxide products for the Pacific Northwest.
IER's primary market was the specialty potato industry that had recently changed from a lye peeling process to the use of steam, resulting in a wastewater stream that flipped from being highly alkaline to slightly acidic.
After a few years of product development and on-site testing, it was found that Magnesium Hydroxide provided the most cost-effective and safe option for boosting the pH while also providing polymer reduction and sludge reduction.
Dr Doug Kelley is added to the team to spearhead product quality improvements and sales growth. At the time, Doug had small children who asked what he did; his response was simply that “we help folks clean their water after they use it”.
Within a few years, IER expands operations to include five manufacturing plants stretching from the Pacific Northwest to Lake Michigan across the northern tier states and Canada.
In 2019, IER was purchased by Calix Australia, with plans to further expand the offerings and markets for continued IER growth.
Today, IER is a recognized leader in the application of Magnesium Hydroxide-based products for wastewater treatment.
