  • A review of sulfide emissions in sewer networks: overall approach and systemic modelling

    The problems related to hydrogen sulfide in terms of deterioration of sewer networks, toxicity and odor nuisance have become very clear to the network stakeholders and the public. The hydraulic and (bio)chemical phenomena and parameters controlling sulfide formation, emission and their incidences in sewer networks are very complex. Recent research studies have been developed in gravity and ...

  • Mastering the Chaos

    Random packing consists of single pieces that are poured into separation columns and form a chaotic structure. Now, Sulzer has developed a new generation of high-performance random packing that offers more uniformity of surface distribution within the packing volume. The example of a CO2 absorber shows the benefits. Columns with random packing are well established ...

  • Control of malodors using Ecosorb - A natural product

    Abstract Ecosorb removes many malodors, including sulfur dioxide, hydrogen sulfide and ammonia, from the environment. It is made up of a combination of essential oils consisting of an equilibrium of neutral organic compounds and organic buffers. Its pH ranges from 4.0 to 6.8. Acidic malodors such as hydrogen sulfide and sulfur dioxide are removed by at least four mechanisms ...

  • Wastewater force main management – internal corrosion survey using inline methods

    In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure ...

  • Seasonal and influent characteristic effects on hydrogen sulfide generation at a water reclamation plant

    Correlations between sulfide generation and seasonal influent wastewater characteristics were identified based on a long-term monitoring program in summer and winter at a water reclamation plant. During summer, the emission rates of hydrogen sulfide (H2S) from the liquid treatment processes increased substantially compared to those during winter due to the increased wastewater temperature. The ...

  • Hydrogen Sulfide and Grease Control in Domestic Sewage Lift Station and force main by the addition of Bio-Organic Catalysts (BOCs)

    Abstract The wastewater from a small section of a southwestern U.S. city was studied. Concerns of grease accumulation and the increasing cost of operation year after year of a current odor control chemistry gave rise to searching for a better solution. There was evidence that grease and slime layers within the pipes and lift station were increasing with the current chemical solution. The ...

  • Screentec success story - the Lower Township, NJ case study

    New Jersey’s Lower Township Municipal Utilities Authority had a problem. The utilities authority operates a 5 MGD plant, with wastewater inflow arriving through a 48-in pipe routed 23 feet below grade level. Their manual inflow pump screening setup was difficult and hazardous to clean, and its 2.5” screen spacing let entirely too much non-dispersible waste through. Their 3,000 GPM ...

  • Hydrogen sulfide gas emission under turbulent conditions – an experimental approach for free-fall drops

    Odor nuisance and sulfide corrosion in sewers carrying septic wastewater are accelerated at points of turbulence such as drops in manholes, but accurate methods or empirical expressions to evaluate the gas stripping rate at those particular sites are still missing. With the aim of improving the current knowledge on the influence of free-fall drops on the release of hydrogen sulfide gas, an ...

  • Hydrogen sulfide removal from sediment and water in box culverts/storm drains by iron-based granules

    A renewable granular iron-based technology for hydrogen sulfide removal from sediment and water in box culverts and storm drains is discussed. Iron granules, including granular ferric hydroxide (GFH), granular ferric oxide (GFO) and rusted waste iron crusts (RWIC) embedded in the sediment phase removed aqueous hydrogen sulfide formed from sedimentary biological sulfate reduction. The exhausted ...

  • Hydrogen Sulfide control in a municipal sewer collection system case study

    Odor and Corrosion Control in Pump Stations Using Microcat – ANL BioBlend – BSE 104 Problem Hydrogen sulfide generated in sewer systems can cause safety and maintenance problems including toxicity to humans, odors and corrosion. Several methods are used to control hydrogen sulfide in collection systems. While many have proven to be at least partially ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Removal of Heat stable salts – A solution to Amine plant operational problems

    Introduction Amine scrubbing solutions are used to remove hydrogen sulfide and carbon dioxide from gas streams in many natural gas conditioning plants and oil refineries. Two major problems represent a significant threat to an amine gas treating plant: corrosion and instability of operation, resulting in unscheduled upsets and outages. In this process, contaminant byproducts called Heat ...

  • Hydrogen sulfide removal from livestock biogas by a farm-scale bio-filter desulfurization system

    A farm-scale biogas desulfurization system was designed and tested for H2S removal efficiency from livestock biogas. This work assesses the H2S removal efficiency of a novel farm-scale biogas bio-desulfurization system (BBS) operated for 350 days on a 1,000-head pig farm. Experimental data demonstrated that suitable humidity and temperature can help sulfur-oxidizing bacteria to form ...

  • Precipitation of heavy metals from coal ash leachate using biogenic hydrogen sulfide generated from FGD gypsum

    Investigations were undertaken to utilize flue gas desulfurization (FGD) gypsum for the treatment of leachate from the coal ash (CA) dump sites. Bench-scale investigations consisted of three main steps namely hydrogen sulfide (H2S) production by sulfate reducing bacteria (SRB) using sulfate from solubilized FGD gypsum as the electron acceptor, followed by leaching of heavy metals (HMs) from coal ...

  • Treament of Hydrogen Sulfide (H2s)

    This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...

  • Cryogenic technology for the removal of h2s in wastewater treatment facilities

    Hydrogen sulfide (H2S; CAS No. 7783-06-4) gas production usually is one of the primary concerns in the wastewater treatment facilities.  Under anaerobic (septic) wastewater conditions, sulfides cannot be oxidized (Palmer, Lagasse, and Maureen 2011). Therefore, they combine with hydrogen to produce hydrogen sulfide gas, creating the "rotten egg" odor associated with septic wastewater (Palmer, ...
