Introduction

Peracetic Acid (PAA) is an organic peroxide compound with the formula CH₃CO₃H. It is environmentally friendly as it hydrolyzes to acetic acid and hydrogen peroxide in water. It is a broad-spectrum biocide with a fast reaction time in minutes and leaves no harmful by-products.

It is a strong oxidant...

Introduction

The use of hydrogen peroxide (H₂O₂) as a pre-oxidant in municipal drinking water treatment is well documented and has been practiced for over 15 years. Historical applications of H₂O₂ in drinking water have been for taste and odor control, hydrogen sulfide removal, iron removal and ozone enhancement/destruction. With the...

Cloevis Biofilm Removal Service (Cloevis BRS) is an innovative technology offering that removes the biofilms that adhere to the inner surfaces of wastewater forcemain walls, including the underlying Sulfate Reducing Bacteria (SRB) that produce hydrogen sulfide. As a result, gaseous hydrogen sulfide (H₂ S) production is eliminated. The treatment requires...

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...
