For the team at Henry N. Wochholz Regional Water Recycling Facility in Yucaipa, CA, seasonal upsets weren't a surprise. They were a pattern.
Every year, nitrification would fail. Biomass would crash. Operators scrambled to respond — and recovery stretched 10 days or more, with compliance risk hanging over every decision.
Reactive interventions kept the plant running, but they couldn't break the cycle.

In November 2024, the facility deployed Moleaer's NanoShield upstream in their existing treatment process — no new infrastructure, no operational disruption.
Rather than treating symptoms downstream, NanoShield stabilized influent conditions before inhibitory compounds could disrupt biological treatment. The benefits cascaded through the entire treatment train.

Performed like water was 10°C warmer, restoring ~70% of lost nitrification capacity
90% fewer ammonia upsets and 90% faster recovery
67% lower effluent ammonia
(from 0.18 to 0.06 mg/L)
~20% increased treatment capacity
Consistent Title 22 reuse compliance


Yucaipa didn't build their way to better performance. They optimized what they already had.
For utilities facing tightening standards, aging infrastructure, and growing pressure to expand capacity — that's a replicable model.
