MBR vs. CAS: Why MBR Is the Smarter Long-Term Investment

If you’re still comparing wastewater treatment systems by kilowatt-hour alone, you’re missing the real cost drivers.

This in-depth white paper cuts through the outdated metrics and makes the financial case for Membrane Bioreactor (MBR) technology over conventional activated sludge (CAS) systems, factoring in everything from operating cost and effluent quality to long-term environmental impact and treatment efficiency.

What You’ll Learn:

  • Why sludge disposal now accounts for up to 50% of OPEX in conventional plants—and how the MBR process cuts those costs by 30–50%.
  • How MBR’s small footprint and modular design unlock new development potential for space-constrained facilities.
  • Where MBR vs. CAS delivers measurable ROI: labor, chemicals, maintenance, and compliance when compared to the conventional activated sludge process.

Whether you’re planning a new wastewater treatment system, evaluating an upgrade from a conventional activated sludge setup, or trying to future-proof against rising disposal fees and stricter discharge limits, this paper gives you the data and insight to make the right investment.
