Project Scope

A remediation contractor received a contract to clean up a former Manufactured Gas Plant (MGP) waste collection area. After thorough site characterization, bench testing and a pilot study, the consulting engineer and the remediation contractor selected the contractor’s patent-pending, surfactant-enhanced In-Situ Chemical Oxidation (ISCO) as the treatment technology....

Introduction

Nitrogen oxides are major pollutants in the atmosphere and are a precursor to acid rain, photochemical smog, and ozone accumulation. The oxides are mainly nitric oxide (NO) and nitrogen dioxide (NO ₂ ), both of which are corrosive and hazardous to health.

Stationary Source Focus

With the use of...

Introduction

Wastewater streams and process baths at metal surface finishing operations can be very challenging to effectively treat. USP Technologies (USP) can help metal finishers and processors by characterizing each unique situation and matching it to our technically sound and proven options for NOx emissions control in stainless steel and...

Odor & Corrosion Best Practices Webinar

ABSTRACT

In August of 2012, Monroe County DES initiated a demonstration of Peroxide Regenerated Iron – Sulfide Control (PRI-SC^®) technology as a performance improvement over the existing hypochlorite and hydrogen peroxide odor and corrosion control program. This demonstration was designed to control hydrogen sulfide (H₂S) odors and corrosion along...

ABSTRACT

Historically the technology to continuously monitor “odors” or odor units in real time has not been available. Since October 2009, the Hampton Roads Sanitation District (HRSD) has been successfully demonstrating new technology that is performing real time odor monitoring of the odors from the uncovered portion of the...

ABSTRACT

The Orange County Sanitation Districts (OCSD) currently utilize PRI-SC^TMtechnology to control hydrogen sulfide emissions within its collection system. With PRI-SC^™, ferrous chloride (FeCl₂) is added for sulfide control and then the combined iron is regenerated using hydrogen peroxide (H₂O₂). OCSD also adds ferric chloride (FeCl₃) at its treatment plants...

Total Chemical Management for Remediation

A remediation company was contracted to perform a cleanup of an abandoned gas station in south central Pennsylvania. The consulting engineer and the remediation contractor selected a treatment program utilizing In-Situ Chemical Oxidation (ISCO) as the preferred treatment technology. Due to the magnitude of the contamination and...
