Environmental Operating Solutions

What Environmental Operating Solutions does

Environmental Operating Solutions, Inc. (EOSi), founded in 2003 and headquartered in Pocasset, Massachusetts, develops and supplies non-hazardous supplemental carbon sources and automated dosing technology for biological nutrient removal (BNR) at municipal and industrial wastewater treatment facilities. The company operates four proprietary MicroC product lines — MicroC 1000 (carbohydrate-based), 2000 (glycerin-based), 3000 (alcohol-based), and 4000 (custom formulations for selenium, perchlorate, and drinking water applications) — sold in packaging ranging from 5-gallon pails to 4,500-gallon bulk tanker deliveries. EOSi has stated product deployments at 550+ customer plants across North America, supported by a network of 20+ manufacturing facilities, 165 million pounds of annual MicroC output, 40,000 deliveries per year, and 20 in-house QA/QC laboratories.

EOSi's second product axis is the Nitrack automation platform, including the cloud-based Virtual Nitrack system (built on Microsoft Azure and Inductive Automation's Ignition) and the Nitraskid-IQ integrated pump skid, which feed-forward and feedback-control loop dosing of MicroC in real time. These products are positioned as non-hazardous alternatives to methanol, with claimed 20%+ customer chemical cost reductions and integration into customer SCADA/PLC environments. The go-to-market is direct enterprise field sales via territory managers, complemented by technical engineering services (program evaluation, bench-scale testing, modeling, optimization, and ongoing monitoring) that constitute a managed-services revenue stream alongside product sales.

EOSi has operated as a core business unit of the Axius Water platform since 2019, when the platform was founded by KKR's Global Impact Fund and XPV Water Partners. Axius Water has since consolidated additional water treatment companies (Aero-Mod, S&N Airoflo, Napier-Reid, Triplepoint, Nexom, EDI, MITA, ATAC), and in May 2026 announced a definitive agreement to be acquired by CRH, a global building materials company.
