ABSTRACT The Sanitation District 1 (SD1) located in northern Kentucky changed the structure and nature of the odor control program with positive results. A disciplined and data based odor control program was implemented in 2005. A supplier was selected to supply an odor control program and deliver results at various control points versus fragmented purchasing of products and technologies. Data is rigorously collected at each control site on a monthly basis and reported to SD1 by the odor control suppler. SD1 uses the data including hydrogen sulfide vapor concentrations to optimize the chemical addition program. The rigorous and data based approach to odor control has resulted in several positive benefits to SD1 as follows:
Better customer service – SD1 has logged significantly less odor complaints from over 50 in 2004 trending less than 10 for 2006 (2 to date).
Improved trend in chemical control – SD1 has measured significant improvement in quantity of chemicals used on a daily, monthly and annual basis by 25% (Jan-May 2006)
Better performance from chemical purchased – Lower concentration of hydrogen sulfide is emitted.
Teamwork and accountability from the supplier – Supplier is involved in the odor complaint response process.
Improved program management – Proactive ability to forecast seasonal hydrogen sulfide loading and make adjustments to prevent hydrogen sulfide emission.
This work will elaborate on the methods used and measurable results generated from the approach to odor control utilized by SD1.
INTRODUCTION Proper odor and corrosion control is a critical element in the long term satisfaction of stakeholders to the operation of wastewater collection and treatment systems. In 2005 the Sanitation District 1 located in northern Kentucky completed an upgrade to the odor control program in servicing the wastewater collection and treatment system. The odor control program upgrade included the following processes and changes:
Restructured odor control contract with focus on results.
Equipment upgrades.
Data based management of odor control points.
Vender accountability to odor complaint responses, service and reporting.
Multiple technologies and chemistries provided under one supplier.
Single source versus fragmented commodity purchasing.
The number of pump stations and length of force mains combined with the proximity of residents provide a high level of sensitivity to odor control by the district. Changes in the odor control program have reduced the number of odor complaints from greater than 50 in 2004 to less than 30 for all of 2005 and down to 2 pertinent complaints through five months of 2006. Better performance has allowed the district to focus on core activities with maintenance and operation of the existing collection and treatment system.

ABSTRACTThe paper will present results of a trial initiated in February 2004 by the San Antonio Water System (SAWS) to quantify the impacts of hydrogen peroxide injection prior to dissolved air flotation thickening of wastewater sludges.
Since February 2000, the San Antonio Water System has successfully used iron salts (FeSO4) for odor and corrosion control in the Dos Rios Water Recycling Center (WRC) collection system. In May of 2003, the Dos Rios WRC began receiving about 300,000 gallons per day of a mixture...
Odor control is a critical component of the Orange County Sanitation District’s (the Sanitation District) planning and operations. The Sanitation District’s two wastewater treatment plants (Fountain Valley, CA and Huntington Beach, CA) were isolated when originally constructed in the middle of the 20th century, but are now surrounded by high-density residential areas as well as highly used recreational areas, such as Huntington Beach and the Santa Ana River Trail. The Sanitation District has made odor control a...

The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility located in Hilburn. From the earliest stages of development,
RCSWMA has focused on odor control provisions for the...
`In four years, half of San Diego may be filling its glasses with tap water that once ran through its toilets,` reported the San Diego Union-Tribune recently. A plan to mix `repurified water` with the City`s raw drinking water reservoir could become a reality, thanks to the wonders of water treatment technology.
Such a possibility elicits various reactions including disgust, marvel and fear. Although the public generally trusts and admires modern technology, politicians and even scientists fear the grave repercuss...

Massachusetts became home to two new composting facilities that process MSW and biosolids. Nationally, the total number of operating plants is 19.
Since the mid-1980s, BioCycle has been conducting an annual, nationwide survey of municipal solid waste (MSW) composting facilities. From the late 1980s into the early 1990s, when it was projected that landfill capacity would drop and tipping fees would skyrocket, interest in MSW composting was high. About two dozen companies were marketing systems and equipment, and...
The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites.
The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of over 350 animals, including heifers and calves. Most of the herd is housed in freestall barns. About 90 percent of the...
In all, the 1990s have been good for the biosolids recycling community. Greater quantities of biosolids are being beneficially used than ever before, there are national biosolids regulations that are widely accepted as a good baseline, and there is an extensive, accessible network of researchers, practitioners, advisers and public officials who when combined, provide thousands of years worth of valuable knowledge and experience.
We end this decade, however, with perhaps a greater challenge than we started with —...
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...
When a composting facility is at the edge of the cliff with regard to public acceptance or regulatory approval, it must decide to play or fold. Playing means adapting and moving up the evolutionary ladder. Folding means the perceived cost is too much to bear. When I was manager of the Cedar Grove Compost facility in Seattle, Washington (see preceding article, “Composter Bounces Back From The Brink”), we decided to play. The specific measures taken at our facility are described in that article; in this report,...
The largest composter in the state of Washington, Cedar Grove Compost Company in Seattle, had its hands full of challenges in 1997 — confronted with a half million dollar fine, a lawsuit, and angry neighbors. With the adoption of an Environmental Management System (EMS), the compost facility has turned its precarious situation around and stayed in business, while dramatically cutting odor problems. With a generally satisfactory full year under its belt, the composter is looking forward to even better results in...

Sustainable development in this rapidly changing region has become an imperative, and must take place in the complex context of a diverse and changing ecosystem, political transition and evolution toward market economies.
The region is heading towards integrating environmental components into sectors like...
Twenty-five miles west of Dayton, Ohio is the county seat for Preble county - Eaton, Ohio, population 8,000. As the only city in this largely rural county, Eaton finds itself the focus of residential and commercial development transforming it into a bedroom community for Dayton as well as Cincinnati 50 miles to the south.
Participating in this transformation is the Eaton Wastewater Treatment plant. From the original facility in 1909, the Eaton plant has upgraded and expanded to a treatment capacity of 1.9...
Three technologies that are most commonly used to treat halogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation.
Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is `activated` for this purpose by processing the carbon to create porous particles with a large internal surface area (300 to 2,500 square meters per gram of carbon) that attracts and adsorbs organic molecules...
Introduction:
As for in situ solidification/stabilization (S/S), ex situ S/S contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Ex situ S/S, however, typically requires disposal of the resultant materials. Under CERCLA material can be replaced on site.
There are many innovations in the stabilization and solidification technology. Most of the innovations...
Introduction
The utilization of fungal biodegradation involves the controlled usage of these specially cultivated fungi to treat contaminants.
White Rot Fungus
White rot fungus has been reported to degrade a wide variety of organopollutants because of its lignin-degrading or wood-rotting enzymes. Two different treatment configurations have been tested for white rot fungus, in situ and bioreactor. An aerobic system using moisturized air on wood chips is used in a reactor for biodegradation. A reactor was used...
The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the process is more difficult to verify.
Physical/chemical treatment uses the physical properties of the contaminants or the...
There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use of lower-dose pesticides has been a key contributor to the fall in weight of active ingredients sold in recent years....
On 12th March 1997, the European Commission adopted a proposal from the Environment Commissioner Ritt Bjerregaard on a European Union strategy to combat acidification. The strategy will, by 2010, reduce significantly the extent of the areas in the European Union where the tolerance of sensitive ecosystems to acidity is exceeded. Main elements of the strategy include establishment of national emission ceilings for each acid rain pollutant; ratification of the UN protocol on further reductions of sulphur emissions;...
` 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...
INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology.
Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of `dry` operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the kiln exit have proven an effective alternative to infiltration air. Typical installation locations are shown in the dry...

The first case history covers oily waste water treatment at a major aluminum beverage can manufacturing plant. The second case describes treatment of waste water from a multi-plating bath section of a major wheelchair manufacturing facility. The mechanisms of separation effected by both UF and RO are described at the molecular...
A process for manufacturing explosives produces an ammonium nitrate-laden wastewater, which can be successfully treated with reverse osmosis (RD). Key to RD use is balancing the competing waste solution chemistry requirements of the two target solutes, to enhance the performance of the particular RD membrane chosen. While the EPA requires only the reduction of the N03 and NH4+ discharge levels one manufacturer has chosen the approach of reusing both permeate and concentrate streams to `close the loop.` A lab-scale...
