At the end of the article “Projects To Get CPF Cash” [East Hampton Press, October 8], Bud Dunbar is quoted as saying, in reference to a technique alleged to have been developed at the Stony Brook Center for Clean Water Technology, “It has the potential to get nitrogen numbers down way … into the single digits, which none of the commercial technologies have.”

This is most disappointing, as Bud knows that his statement is incorrect, and that there is little new in the center’s technique.

It is well known that the Nitrex technology (which the center technique tries to emulate) reliably achieves total nitrogen (TN) of 3+/- mg/L and has been around since 2001 and independently proven by Barnstable County, Massachusetts, in 2001, the U.S. Environmental Protection Agency in 2004, Suffolk County in 2013, Florida in 2013, and numerous other states, including Utah, which has recently approved its use to achieve TN levels below 2.5 mg/L.

At Captree State Park in Bay Shore, Nitrex is currently achieving effluent TN of 4 mg/L for wastewater that has 2.5 times the amount of nitrogen compared to that of residential wastewater. Similarly, at Connetquot State Park. Nitrex is also permitted by Suffolk County with the Hampton Boat Houses project serving 37 townhouses recently approved by the county to accept and process wastewater.
