Continuous Hydroxyl Odor & Corrosion Control

Maintenance is scheduled.
Contamination is continuous.
Pyure lives in the gap.

Hâ‚‚S costs U.S. wastewater utilities roughly $14 billion annually in infrastructure damage and replacement. In the hours between maintenance visits, Hâ‚‚S and ammonia accumulate in headspaces and wet wells.

Pyure operates 24/7, generating hydroxyls that break down Hâ‚‚S and ammonia inside wet wells, lift stations, headspaces, and HVAC systems, reducing corrosion and eliminating odor complaints.

Pyure in the Field.

Working Installations Case Studies. Municipal and industrial wastewater.

Problem

Severe Hâ‚‚S corrosion in the headworks. Hâ‚‚S originated from an upper vault at the property line, traveled downhill, and entered through the air handler intake, attacking screens, grit classifier, blowers, and grit slurry pumps.

Pyure solution

MVP14 hydroxyl generators installed to reduce Hâ‚‚S reaching the headworks. Pyure IDU units subsequently added to HVAC air handlers supplying fresh air to chemical storage and pump rooms.

Measurable outcome

Corrosion in treated areas effectively stopped. Seven-year follow-up shows minimal new corrosion accumulation since Pyure installation. Plant operators report drastic reduction in odor and worker irritation.

Problem

High Hâ‚‚S levels in deep pump-station infrastructure causing both odor complaints and corrosion concerns.

Pyure solution

Multi-unit Pyure installation with dedicated odor-control ducting. Technology distributed through an odor-control duct manifold, treating the headspace directly.

Measurable outcome

Hâ‚‚S reduced to within the OSHA safety envelope. Infrastructure protection ongoing.
