Stony Brook Researchers Unveil Tech for Newer, Cleaner Septic Systems

The Center for Clean Water Technology (CCWT) at Stony Brook University announced on Friday that its updated sewer system for wastewater treatment can be installed across Suffolk County as early as June 2022.

CCWT staff presented research at a Zoom conference and spoke to reporters about the latest developments in the fight against groundwater pollution. The technology is an on-site sewage system with nitrogen removing biofilters (NRAs) and would reduce the harmful chemicals 1,4-dioxane and nitrogen from sewage.

“This is great news,” said Adrienne Esposito, director of the Citizens’ Campaign for the Environment, which was also its turn. “We want to prevent pollution before it gets into the groundwater, and Stony Brook has found a tool to do that.”

Dr. Christopher Gobler, director of CCWT, said the NRAs have now moved from experimental to pilot in Suffolk. NRBs remove nitrogen from wastewater “in or better than a sewage treatment plant” and remove most pathogens and phosphorus.

CCWT expects that from June 2022 onwards, the NRAs for their own sewage treatment plants can be installed in the houses in Suffolk in order to cause “the homeowners only little out of pocket costs”.

Gobler stated that state, state, and local grants would be available to residents to help them pay for the installation, which would cost about $ 20,000. He added that the cities of Southampton and East Hampton also offer grants for the system.

CCWT’s research study on the effects of 1,4-dioxane and nitrogen on water quality and contaminant removal, “Removing 80-90% of Nitrogen and Organic Contaminants,” was published this month in the Journal of Ecological Engineering, an international peer , publishes verified scientific paper.

CCWT was founded in 2015 and started its NRB project in 2018. For more information, see
