The Falmouth Water Quality Management Committee convened on October 23, 2024, to discuss advancements in wastewater treatment technology that promise to enhance local water quality while minimizing energy consumption. A key highlight of the meeting was the presentation of a new recirculating media filter system, which is set to replace older methods that have proven less efficient.

The new system utilizes a trickling filter technology that has been refined over the years. Unlike traditional sand filters, which require a larger footprint and higher maintenance, the recirculating media filter significantly reduces space requirements and energy use. According to the presentation, this innovative approach can treat up to 25 gallons per day per square foot, compared to just 3 gallons with older systems. This efficiency translates to an annual electricity cost of approximately $50, primarily for lifting water, making it a cost-effective solution for the community.

The committee also discussed the limitations of extended aeration systems, which are less suitable for small flow applications due to their susceptibility to varying conditions. The new technology not only improves nitrogen removal rates—achieving about 50% efficiency—but also minimizes sludge production, which has been a concern for property owners. The system is designed to operate continuously, reducing the risk of property owners disconnecting it due to high electricity bills.

In addition to the main topic, committee members addressed the importance of ensuring that the denitrification component of the system is adequately sized to handle the wastewater effectively. The meeting underscored the commitment to improving Falmouth's water quality through innovative and sustainable practices.

As the town moves forward with implementing this advanced wastewater treatment technology, residents can expect enhanced environmental protection and a more efficient use of resources, paving the way for a cleaner and healthier community.
