End-to-End Service: Reliability from the Memphis Service Center

Envirogen takes a solutions-based approach to service deionization, focusing on your specific application and goals. Our reliable systems consist of activated carbon and high-quality ion exchange resins in movable exchange tanks connected directly to your plant or incoming feed water. When tanks are exhausted, an Envirogen technician performs an on-site exchange with freshly regenerated tanks to ensure a continuous and uninterrupted supply.

We deliver value-driven solutions designed for operational efficiency:

  • Cooperative Problem-Solving: Our process experts assess your feedwater quality, flow rate, and product water requirements to recommend the most economical and reliable service unit type.
  • No Capital Purchase Required: Achieve your water quality goals with no capital outlay, preserving your budget for core business needs.
  • Memphis Service Center Advantage: We take care of everything—collection, delivery, regeneration, and return—from our highly efficient Memphis, Tennessee facility, providing high-quality pure water with great value.
  • Flexible & Scalable: Our modular systems are easily expanded. If your requirements change, we can simply switch media types or tank sizes, saving you significant capital expense.
