CLOEVIS BIOFILM REMOVAL SERVICE

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...

Cooling Towers Cleaning Applications Using Hydrogen Peroxide

Project Scope

A power plant on the West coast was experiencing problems with its large, open-circuit cooling tower system. Excessive bacterial growth in the tower was leading to solids accumulation within the tower’s fill and an increasing frequency of TSS excursions in their blow down discharges to the local municipal...

Cost Savings and Performance Improvement of Large System Iron Salt Use for Integrated Sulfide Control and Chemically Enhanced Primary Treatment by Using Peroxide Regenerated Iron Technology

ABSTRACT

San Diego’s Point Loma WWTP is a 160 MGD (240 MGD permitted), 100% advanced primary treatment plant that has historically used iron salts for collection system sulfide control and chemically enhanced primary treatment. Beginning in 2006, a PRI-SC® (Peroxide Regenerated Iron – Sulfide Control) program was implemented by adding...

DRINKING WATER TREATMENT – HYDROGEN PEROXIDE PRE-OXIDANT APPLICATION

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...

EFFECTIVELY CLEANING CELLULAR PLASTIC COOLING TOWER FILL

Abstract

The transition from splash fill and ACB fill to cellular plastic “high efficiency” film fill in cooling towers has reduced capital and operating costs. However, the generally tight and tortuous path that provides exceptional contact between air and water in these fills also makes them highly prone to fouling....
