The No-Waste Breakthrough for Drinking Water

BioLargo and Aquatech form a global alliance to trap and destroy PFAS without leaving behind toxic sludge

19 May 2026

Cleaning “forever chemicals” from drinking water has long felt like a frustrating game of environmental whack-a-mole. Standard filters do a fine job of pulling per- and polyfluoroalkyl substances (PFAS) out of the tap, but they leave behind a highly concentrated, toxic sludge that utilities must then figure out how to dump or destroy.

A new partnership between clean-tech developer BioLargo and water treatment giant Aquatech aims to shatter that cycle. The companies signed an agreement this month to integrate their systems into a single, zero-waste process.

BioLargo uses an electrostatic concentrator to draw the chemicals onto a specialized membrane, isolating the toxins without generating a secondary stream of contaminated liquid waste. Once trapped, Aquatech steps in with its full-scale destruction technology to eliminate the chemicals right on-site.

Regulatory pressure is driving the sudden urgency. On January 12, the European Union enacted its first binding, harmonized standards for PFAS limits in drinking water. With compliance deadlines looming, the market for filtering these resilient compounds is booming, and analysts project global spending on PFAS filtration will jump from $2.34 billion this year to $3.28 billion by 2031.

For local water utilities, the financial pressure is immense. Building entirely new treatment plants is rarely an option, meaning modular solutions that plug directly into existing setups hold massive commercial appeal. By pairing a highly efficient extraction method with an established global distributor, this joint effort offers a practical blueprint for a crisis that cannot be ignored.
