"Hartford City is one of four RDP EnVessel Pasteurization Systems located in the greater Indianapolis area. If you would like to come visit us at any time, please call ahead so that we can make arrangements to have the facility operating the day that you visit."

"Hi, my name is Waine Ritenour (far left)! I am the Plant Superintendent at the Hartford City
Wastewater Treatment Plant. This is most of my plant staff and our Project Engineer, Keith Bryant (far right)"

"Our new Administration & Laboratory Building!"


"Part of our new laboratory."

"The circular tank in the foreground was our anaerobic digestor. We had the cover removed
and it now serves as an extra aerated sludge holding tank. We are considering accepting
liquid sludge form surrounding communities. This will enable us to use our reserve
capacity with the Belt Filter Press and RDP System."

"We saved a considerable amount of capital expense by using our
existing Mechanical Mixers/Sludge holding tanks. We average
about 2% feed solids to our Belt Filter Press."

"Here is our Dewatering and Pasteurization Buildings and Storage Structure. The dewatering building
(foreground) was existing. The Pasteurization building (background) is new. We have two 30 ton silos in
case we choose to add a second amendment material. To date, we have only used high calcium quicklime."

"Here is our Ashbrook 1.5 Meter Belt Filter Press (BFP). Gene, our lead
BFP Operator, has increased the cake solids from less than 20% at
start-up to an average of 25%, at a cost of $18-$24 per wet ton."

"Here is our Small Community System ThermoBlender™. Using high calcium quicklime and supplemental heat,
we rise the temperature of the biosolids to about 160°F. This costs us $8-$10 per wet ton,
with the lower cost in the summer (biosolids are warmer) and higher in the winter (biosolids are cooler)."

This is our Pasteurization Vessel. It takes 30 minutes to go from the inlet point to the discharge point. We maintain a minimum of 160°F from beginning to end. We record product temperatures at least every hour. We knew before the process came on line that time and temperature and every particle were emerging important State and Federal requirements. I recently received a copy of the new Revised White House EPA publication and the words 'time', 'temperature' and 'every particle' are thoroughly discussed throughout the publication. We were recently inspected by US EPA Region 5 and passed with flying colors."

"We developed a Product Logo. We initially came up with 4 different logos. We then displayed all 4 when we had our open house. Our visitors that day voted for the Logo of their choice. This is what they voted for by an overwhelming vote.
Credit for the winning Logo goes to Robin on my staff."

"As you can see from the next two photos, we get pretty even distribution. Note: This field is a 160 acre property that the city owns. In 1999, our farmer grew feed corn and beans. This winter he will have a winter wheat crop."

"In the Spring of 2000, we set aside three acres for planting sweet corn. This corn in intended to be given away by our Mayor to any city resident for free."

"We had a very successful yield of corn. Each stalk averaged two
ears of corn and we had an occasional stock with three ears of corn."

"We had so much corn that we donated it to several food banks and assisted living facilities. Next year, we will probably on plant one acre, as we really had too much corn that had to be hand picked."

"In the past year (2000), during the spring, summer and fall we allowed our Class A finished product to sit outside of the storage building. This allowed Mother Nature to reduce the moisture content of our product. The product is then moved back into the inside storage area as you will see in the next photographs."
