2025 01-January 27 -USP Technologies Collection Trials

Goals:

• Mitigate Hydrogen sulfide production between industry, interceptor, and headworks. This can be achieved by maintaining a neutral pH. As the wastewater flows towards the plant, pH tends to drop, increasing the tendency for elemental sulfur to convert to hydrogen sulfide.

Keywords:

• Caustic shocking

Key question:

• What is the ideal interval for caustic shocking?

People:

• Michael Fagan
• Sammy Kohl
• Michael Ratley

Get pH higher to mitigate corrosion, then hit it with peroxide for headworks

Remove sulfur in influent.
