March 2007
In June of 2006, TPS announced the award for construction of a ThermAer™ Process at the Heart of the Valley WWTP in Kaukauna, WI near Appleton. This state-of-the-art 26.4 MGD facility is now in the final stages of startup. The system, including the patent pending SNDR (storage nitrification/denitrification reactor) will be completely operational by the end of April 2007. The plant combines primary and secondary material to be treated in the largest operating ATAD in the World. Please call Thermal Process Systems to set up your visit.
ThermAer Sales are Heating Up
July 2006
Notice of Award has been received on three additional projects. Construction on the Heart of the Valley ThermAer Process for the expansion of the Appleton Wisconsin WWTP has begun. This facility is being expanded to treat up to 26.4 MGD of wastewater from this growing community. McMahon and Associates, Inc. is providing engineering services and opted to catapult this facility into the 21st century by including the well established ThermAer Process for Class A treatment of the biosolids produced.
Additionally, Thermal Process Systems received notification of Award for projects in Towanda, PA and Franklin, IN. The Towanda WWTP in the sensitive Chesapeake Bay Water Shed, with very strict nitrogen and phosphorous limitations, fully evaluated the ThermAer Process and determined that it was the best fit for meeting both the objectives of the WWTP including lowering disposal costs and producing a Class A biosolids material and the objectives of the local regulations providing minimal recycle of P and N to the headworks of the water treatment system and ultimately the water discharged from this BNR plant. The design engineer is Stiffler, McGraw and Associates out of Hollidaysburg, PA.
Franklin, Indiana is replacing their 1st Generation Fuchs ATAD with the 2nd Generation ThermAer. The WWTP loves the ATAD type technology and estimates that the upgrade will reduce additional processing costs associated with the current plant operations by greater than 50%. Engineering and oversite are being conducted by Commonwealth Engineering, Inc. out of Indianapolis, IN.
Delphos, Ohio
June 2006
Construction is competed on the TPS 2nd Generation ThermAer Process located in Delphos, Ohio. This is a "grass roots" facility in northwestern Ohio that replaces the older facility across (town) the street.
The new Delphos facility utilizes MBR technology to treat up to 6 MGD of wastewater per day. The solids from the MBR will be treated in the ThermAer reactor. A storage-nitirfication-detrification reactor (SNDR) will also provide the facility with the ability to reduce recycle loads on the plant while producing a completely stable and odor free Class A material.
Check back for progress of this installation. The startup of this system is planned for the fall of 2006.
Marshall, Minnesota
May 2006
The City of Marshall, Minnesota recently awarded Thermal Process Systems an order for the patented ThermAer™ process for the production of Class A biosolid material. Construction at the plant will transform two existing anaerobic digesters into the 2nd Generation ATADs followed by a storage/nitrification/denitrification reactor (SNDR). This construction is to begin immediately with operations scheduled to commence in the first quarter of 2007. TPS will update the website with construction pictures as the facility progresses through change from Class B to Class A biosolid production. Please feel free to contact TPS or you local manufacturer’s representative to receive a process evaluation on how you can convert your Class B WWTP into a state-of-the-art Class A biosolids production facility.
Morehead, Kentucky
April 2006
TPS’s newest 2nd Generation ThermAer™ process has been in operation for over six months. The results have been very impressive with total solids reduction in excess of 50%.
The Morehead WWTP previously operated two existing anaerobic digestion tanks. As part of a plant expansion, the two digesters were retrofitted into one ThermAer™ reactor and one storage nitrification/denitrification reactor (SNDR) for additional post processing of the treated biosolid material. This batch fed unit operation, provides the facility with the ability to produce Class A Biosolids and the flexibility in the storage tank to campaign dewater on weekly batch runs without sacrificing quality. Additionally, the SNDR allows for campaign dewatering without significant shock loadings to the remainder of the plant. The ammonia is reduced by <70% in this nitrification/denitrification process operation. The plant operations personnel are overjoyed with the success of the project and the lack of odors in the off gas from the biofilter.
We will be issuing a new case study on this installation very soon. If you need additional information, do not hesitate to contact you local manufactures representative or TPS directly. Site visits are welcome and encouraged. Please call TPS to set up your individual tour.
Bowling Green, Ohio
May 2005
TPS’ newest 2nd Generation ThermAer ATTAD process has been in operation for almost two months. The results have been very impressive. The initial data show total solids reduction of almost 65% and there have been no odors detected.
This university town plant originally operated a conventional aerobic digester. Integration of existing tankage with new oxygen transfer equipment is now utilized for liquid biosolids storage and nitrification post processing. This portion of the process reduces the ammonia by over 60%. Reactors were constructed to house the new ATTAD units. These reactors are continuously fed on alternate days to maintain pathogen kill and maximize volatile solid reduction (VSR).
Additional details are forth coming and can be found in the Bowling Green Applications Report. If you wish to receive a copy, phone or email us and we will be happy to send one.
Grand Traverse County
Traverse City, Michigan
August 2004
TPS has recently received a purchase order for a ThermAer™ATAD in Traverse City, Michigan. This ‘grass roots’ facility is being constructed to process and treat 100% of the septage generated from local communities. We believe this to be the first membrane bioreactor process that will discharge directly to an ATAD Reactor for digestion.
Thermal Process Systems’ representative, Solberg & Knowles, has worked closely with Gourdie-Fraser Engineers to iron out the technical issues associated with treating this particular type of wastestream. This ‘fast-track’ project is expected to be in operation within the next 12 months.
Please contact Thermal Process Systems today to discuss your particular ‘special’ digestion application.
Yorkville - Bristol Sanitary District
July 2004
The Yorkville, Illinois ThermAer™ has now been operating continuously for over nine months. During this time, average total solid reduction has been 50% with volatile solid reduction at greater than 65%. The Class ‘A’ biosolid end product is very stable and also odor free.
Recent contract performance testing documented the absence of mercaptans and H2S in the ATTAD off-gas stream. Additionally, the biofilter odor control system has been very effective in removing ammonia produced in TPS ATTAD unit with an overall ammonia reduction of >99.99%.
The Yorkville-Bristol Sanitary District plant personnel love the simplicity of our process. They have been very gracious in allowing numerous tours of the newest 2nd Generation ATTAD operation. Please call Thermal Process Systems at 219-663-1034 to set up a tour and take a look for yourself.
Brunswick County, North Carolina
May 2004
Thermal Process System’s patented ThermAer™ Autothermal Thermophilic Aerobic Digester was the basis for solids digestion system to be installed in Brunswick County. This “grass roots” treatment facility located in the southeast corner of North Carolina is designed to treat average local flow requirements with the ability to scale up to 2x to 3x the load during the peak tourist season. Conceptual engineering and equipment selection was done by HDR, Engineering. The detail plant design was completed by McKim & Creed from their office in Wilmington, NC. HDR is now responsible for construction administration and oversight at the facility.
This project includes two completely automated ATAD reactors followed by an integral biosolids nitrification/storage tank. Additionally, the TPS Biofilter/odor control system will treat the off-gas airstream from the process. This will be the first “Second Generation” ATAD in the state of North Carolina. Startup of the system is scheduled for December 2005.
Congratulations to our representative PROSYS Sales for a job well done!
Greenfield Indiana Waste Water Treatment Plant
December 2003
The City of Greenfield's Biofiltration System, for the current wastewater treatment plant renovation, has been shipped and is now on site and awaiting installation. This innovative design includes a fully automated, low maintenance, biofiltration bed and separate wet scrubber. Although, similar to the Missoula Montana packaged biofilter concept installed in November 2003, this biofilter unit has been designed with the process components, piping, and control unit pre-assembled and ready for a quick and easy on-site installation.
Biofiltration is the often the first choice as a proven and effective method of treating odorous gas generated from various process operations including wastewater treatment plants, pump stations, composting facilities, and solid waste processing facilities. Thermal Process Systems has designed and installed over 30 biofilter systems with capacities ranging from 100 scfm to over 60,000 scfm. The City of Greenfield provided the design parameters including unit capacity of 1,500 scfm, removal of 99% of the average 15 ppm H2S (Hydrogen Sulfide) concentration and 95% removal of the 50 ppm ammonia concentration. The TPS Biofiltration system was selected because of its:
- High removal efficiency
- Low capital cost
- Low installation cost
- Low maintenance cost
- Low operating cost
The biofiltration media bed, soaker hose header system, and control panel (click on thumbnails to enlarge) shown below are installed and scheduled for start-up in the Spring of 2004.
Missoula Montana
November 2003
Here are two pictures of our "Biofilter Package". Since most of it arrived pre-assembled there is very little assembly work required. The large tank is a biofilter bed and scrubber in one while the small shed houses the water piping, fan, recirculation system, electrical components, and control panel. The majority of the system arrives already built so after placement there is very little work outside of external connections.
