HD Q-PAC® Bio-media Eliminates Odors at Mt. Dora, Florida Water Reclamation Plant. System Very Responsive to H2S Surges
Courtesy of Lantec Products, Inc.
The water reclamation plant at Mt. Dora, Florida
had an odor problem at the headworks collection
well. Several pump stations in the community send
their water to this location. The discharge of the
various lines is random. At times one line may be
discharging water while other lines are idle. At other
times multiple lines are discharging. There are
periods of no water discharge at various times
during the day. As a consequence, hydrogen
sulfide (H2S) levels vary greatly from hour to hour
and even from minute to minute.
The Mt. Dora WWTP needed a reliable, inexpensive, easy-to-operate odor control system. Like other municipal wastewater treatment authorities, Mt. Dora preferred a biological odor-control system to a chemical wet scrubber. Chemical scrubbers can react instantly to changes in the H2S loading. Biological systems, though much less expensive to operate over time due to zero chemical demand, have a reputation for reacting slowly to changes in sulfide loading. Mt. Dora therefore accepted a full-scale biotrickling odorcontrol system from a consortium of companies, on the condition that no purchase order would be issued until such time as the system proved itself to be capable of eliminating odors and providing quick response to frequent changes in malodorous gas loadings.
Odor Control H 2 S / Sewer Gas Wet Scrubbing Explained
H2S / Sewer Gas / Rotten Egg Smell ControlHydrogen Sulfide, chemical formula H2S. also commonly referred to as `sewer gas` is frequently a nuisance problem at waste water treatment facilities - and a source of complaints from neighbors of such facilities.Additionally, H2S not only stinks, at high concentrations it incapacitates, blinds and eventually will kill if allowed to concentrate fiulher. And as it is heavier than air. if not controlled it can under proper circumstances collect undetected in low places such...
Chemical Industry: Wet Scrubber Passes Acid Anhydride Test Case Study
A leading U.S. chemical company upgraded air pollution control of maleic anhydride fumes at one of its overseas plants by installing a venturi scrubber. Selection of the scrubber was based on a pilot study to determine the percentage recovery and the maximum solution concentration of maleic anhydride that could be achieved using a wet scrubber. One significant reason for pretesting the installation is that maleic anhydride fumes sublime. This makes it· impractical to predict particle size and calculate...
The Italian Job
Open loop systems abstract groundwater from one or more boreholes. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate well or body of water. The supply and return lines need to be placed far enough apart to ensure thermal recharge of the source. The key issues for open loop systems relate to borehole yields, licensing and, most importantly, flow rates. A number of factors can affect flow rates and one that could be easily managed, and yet is becoming an...
Advancing Odor Control to New Levels Gurnee Sewage Treament Plant North Shore Sanitary District
ABSTRACTThe North Shore Sanitary District (District) owns and operates a 24-mgd sewage treatment plant located in Gurnee, Illinois. Frequently, odors from the two-stage activated sludge plant’s solids handling facilities made their way into the adjacent residential neighborhood. A new two-stage odor control system for the plant’s solids handling facility was put on-line in October 1999. This system consisted of three parallel mist scrubber trains, with each train consisting of two sodium hypochlorite scrubbers...
Long Term Full Scale Comparison of Activated Sludge (AS) With Biological Aerated Filter (BAF)
The Wastewater Treatment Plant (WWTP) of Frederikshavn, Denmark, was extended in the early nineties to increase its average daily flow to 4,5 MGD (16,500 m³/d) and meet new requirements for nutrient removal (8 mg/l TN, 1,5 mg TP/l). A parallel biological aerated filter (BAF) was the selected as the most economical upgrade of the existing activated sludge plant (AS), and started up in 1995. Running two full scale processes in parallel on the same wastewater and treatment objectives for over ten years enabled a...
Application of Biotrickling Filter for Odor Control at The Morris Forman Wastewater Treatment Plant
Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. Currently, two recuperative thermal oxidizers are used to treat odorous emissions from various sources. The pilot study showed that it is possible to treat hydrogen sulfide and organic sulfur compounds at high removal rates to achieve exit odor concentrations below the levels currently attained by the thermal oxidizers....
Waste Water Treatment Plants
In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within acceptable regulatory limits, allowing the gas to be burned on-site to generate steam for heat or electricity or...

Longer Life For Biofilters
Biofilters are the odor control system of choice at composting facilities. Despite similar capital costs, the biofilters are generally less costly to operate than chemical scrubbers. The key to keeping operating costs in check, however, is to get the maximum use out of the biofilter media, thus avoiding the time and money needed to do media replacements. Allen Boyette, senior engineer and manager of the Cary, North Carolina office of E&A Environmental Consultants, Inc., tackled the topic, “Building Longevity...

In-well Vapor Stripping - Technology Overview
In-well vapor stripping technology involves the creation of a ground-water circulation pattern and simultaneous aeration within the stripping well to volatilize VOCs from the circulating ground-water. Air-lift pumping is used to lift ground-water and strip it of contaminants. Contaminated vapors may be drawn off for aboveground treatment or released to the vadose zone for biodegradation. Partially treated ground-water is forced out of the well into the vadose zone where it reinfiltrates to the water table....
Natural Attenuation in Soils
Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the subsurface soil matrix. These persistent organic contaminants often are difficult to degrade and the inorganic metals are...
Optimizing Wastewater Treatment
` Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical requirements for industrial wastewater treatment. This note presents an approach to making coherent decisions on levels...
Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep geologic disposal is the best method to dispose of the most radioactive waste. Geologic disposal is the permanent burial of...
