Cranfield spin-out Pazul raises £600K for reagent-free phosphate sensing
What's the deal? PazulDealroom has a profile for this one. Try Dealroom →, a spin-out from the UK's Cranfield University, has raised £600,000 to develop real-time phosphate sensing for wastewater treatment and river monitoring. Midlands MindforgeDealroom has a profile for this one. Try Dealroom → led the round with a £300,000 commitment, matched by a group of high-net-worth individuals. The deal was announced on October 21, 2026.
What's the endgame? Pazul builds on research from Cranfield's Water Science Institute. Its electrochemical sensor, based on molecularly imprinted polymers, measures phosphate within minutes without wet chemistry reagents or sample preparation.
Why now? Current lab analysis relies on wet chemistry methods developed in the 1960s, with results arriving one to three days after sampling. Pazul says this makes rapid decisions difficult when water quality can change quickly.
The sensor underpins two products. The first is an automated phosphate iron dosing system for wastewater treatment, which uses real-time measurements and flow data to optimise coagulant dosing and cut chemical use. The second, Pazul RiverIntel, is a real-time river water-quality data service combining continuous sensing, connected data, and analytics to support monitoring, AI tools, and digital twins.
What did they say? "We're extremely proud to have received this investment," said Ana Soares, co-founder and chief technology officer. "It will help us further develop our technology and strengthen our team, but it also shows confidence in the work that we're doing."
What could go wrong? The funding is a step toward field validation and commercial deployment, but its payoff depends on proven reliability and utility adoption.
The signal: The round lands as UK water companies enter AMP8 (2025–30), a major investment period for wastewater upgrades and phosphorus reduction. Government targets call for phosphorus discharges from treated wastewater to fall substantially by 2030, with a further cut by 2038 — raising the value of faster process monitoring.
