Mr. Harrington:Then give them 3 options <br /> Chair Baumgaertel: I would rather have their engineer come up with the option and present <br /> that. They have come up with something but to me it is not a workable option. The layer cake <br /> system, is something that is near and dear to me because I have worked on it a long time. <br /> Mr. Harrington: What type of layer cake is acceptable to you? What do they need to do to it to <br /> make the numbers that would be acceptable to you? <br /> Chair Baumgaertel: The best option of the designs that we have worked on would be the box <br /> technology which is very similar to Nitran. The box technology that we have at the test center <br /> and seen in field results in Suffolk County and Long Island area because they have installed <br /> some of these down there. <br /> Mr. Harrington: Did you say box B O X, box technology? <br /> Chair Baumgaertel: Yes,the box. It is a leach field that has a wire underneath it to catch all the <br /> nitrified effluence coming from the leach field and that goes into a tank full of wood chips for <br /> denitrification. It's very similar to the Nitrex system installed on Main Street. Instead of using a <br /> water bio-filter for nitrification, it's utilizing a single pass low rate sand filter for primary <br /> nitrification and then into the wood chip denitrification tank. That is the design we have been <br /> working with but that comes with the scientific caution that we don't have as to the efficacy of <br /> that in a larger flow like this would be. We have not done that research. I know of the <br /> technologies out there that are not the non-proprietary ones that demonstrated some <br /> performance data that are capable of doing those larger flows. It would be the first two that <br /> come to the list but it's not a totally exhaustive list but would be the Nitrex technology and the <br /> newer Nitro technology,the large flow which I believe they call the 10KM, I don't remember <br /> what the designation is for the larger flow but they do have a cluster flow size system that <br /> might be able to accommodate this. If they were to look at those, I think the performance data <br /> I have seen from those is better and more reliable. Again, it's not an exhaustive list,there may <br /> be other technologies out there that I am not aware of that could be used here. I would not <br /> want to just recommend, it's not a formal recommendation of those two options. <br /> Mr. Harrington: Something formal must be presented to Town Counsel. Can we put these <br /> forth as a recommendation to see if the owner would agree to any of those systems? In my <br /> opinion it is highly unlikely that the owner would do that because they wanted to shy away <br /> from any of the manufactured type of systems that carried the heavy O&M with them. But if <br /> this is where we can get the best nitrogen removal from the property, this is where we need to <br /> be. If you're leaning towards fighting the good fight all the way through,this will give them <br /> something and if they agree to it; it will be a win-win. <br /> Ms. Patel: Is the owner looking for something cost-effective to him? Is that the reason why <br /> he's fighting not putting in a new Title 5 system? I'm wondering if he's trying to find some cost <br /> effective method to do this, is there some funding that we can propose? <br />
