The Use of Iron Salts to Control Dissolved Sulfide in Districts' Trunk Sewers
Headspace H2S removal via the precipitation of dissolved sulfide was investigated using iron chlorides. Full-scale experiments were conducted in...

Tests for Biogenic Sulfuric Acid Corrosion in a Simulation Chamber Confirms the On Site Performance of Calcium Aluminate Based Concretes in Sewage Applications

Sensitized Photooxidation of Dissolved Sulfides in Water
The ability of methylene blue (MB) and riboflavin (RF) to sensitize dissolved sulfides for photooxidation was investigated. Both MB and RF were found to be effective sensitizers for the...

Caustic Spray for Sewer Crown Corrosion Control
A novel method to control sewer crown corrosion which involves spray application of a caustic solution to the sewer crown is described. Corrosion control using this concept is based on...

Proactive Odor Control Using Computer Modeling
The City of Los Angeles (City) is currently designing the East Central Interceptor Sewer (ECIS) as a major relief sewer. The pipeline will convey wastewater flows that originate upstream...
