2018-12-6  Hydrogen sulfide typically forms in “septic “conditions, i.e. when the wastewater stops moving in the collection system. The wastewater then becomes anaerobic and the SRBs (sulfate reducing bacteria) go to work. The hydrogen gas converts to sulfuric acid by the bacteria Thiobacillus living above the water line. The acid then drops back down

2000-12-28  Hydrogen sulfide (H2S) gas typically is formed in wastewater collection systems that are conducive to creating septic conditions. Collection systems in warm climates that have a flat grade or do not have the flow-through velocities (minimum two feet per second) to prevent the stagnation of fluid, allow the septic conditions to occur.

Hydrogen Sulfide Corrosion Subject of EPA Report

2018-5-23  is that hydrogen sulfide corrosion is not an insignificant nor an isolated problem in waste-water systems. “Hydrogen sul-fide corrosion is a well-known and documented prob-lem in wastewater collection and treatment systems throughout the world. The pres-ence of hydrogen sulfide can lead to rapid and exten-sive damage to concrete and metal

Odor and Corrosion Control in Wastewater Collection

Hydrogen sulfide becomes a corrosion issue when it comes into contact with moist concrete or steel, among other metals, in the presence of oxygen, even at very low gaseous concentrations. Conditions such as these are fairly common in the headspace of some pipes as well as at manholes, lift stations, and other areas where the collection

Hydrogen sulfide removal from wastewater using

2021-3-4  Problems of sewers corrosion and odor release are always associated to sulfide presence in waste water. This inorganic compound can occur under different oxidative states such as HS −, S 2− SO 4 2− and H 2 S liq.However, the emission of hydrogen sulfide is due to the presence of H 2 S Liq only. The purpose of this paper is to study the effect of peroxide treatment on sulfide abatement in

Chapter 4 Hydrogen Sulfide and Sulfuric Acid Estimation

2011-8-23  The root cause of odor and corrosion in collection systems is sulfide, which is produced from sulfate by bacteria residing in a slime layer on the submerged portion of sewer pipes and structures. Once released from the wastewater as hydrogen sulfide gas, odor and corrosion problems begin.

Causes of Corrosion OBIC

2021-5-12  Hydrogen-sulfide corrosion (H2S) will always be a problem. Hydrogen-sulfide corrosion, or H2S corrosion, occurs as an acid attack caused by the biological conversion of hydrogen-sulfide gas (H2S) to sulfuric acid (H2SO4), in the presence of moisture. Of course, there is always moisture present in a sewer system.
