News Summary
The Coronado City Council is considering the use of nanobubble technology to address water pollution from sewage flows. Presented by Councillor Amy Steward, the technology aims to enhance water quality and ecosystem health. Nanobubbles can deliver oxygen deep into water, helping to restore nutrient cycling and combat harmful bacteria. A successful case study at Lake Elsinore has inspired the Council to explore this innovative solution further for Coronado’s water challenges.
Coronado City Council Explores Nanobubble Technology to Combat Water Pollution
During a recent meeting, the Coronado City Council discussed the introduction of nanobubble technology aimed at tackling water pollution issues related to sewage flows. Councillor Amy Steward presented this innovative method, which promises to enhance water quality and promote healthier aquatic ecosystems within the city.
Nanobubbles, which are gas bubbles that measure 2,500 times smaller than a grain of salt, possess unique properties that allow them to remain suspended in water without rising to the surface. This enables them to deliver essential elements like oxygen or ozone deep into the water column and sediment for an extended period, often lasting days or weeks.
The core objective of applying nanobubble technology is to mitigate pollution that leads to depleted oxygen levels in water. Low oxygen situations encourage the growth of harmful anaerobic bacteria, which in turn produce toxic byproducts such as methane and sulfides that threaten marine life. By introducing oxygen through nanobubbles, the environment can promote aerobic bacteria that assist in breaking down these contaminants, thus aiding the restoration of nutrient cycling in aquatic settings.
Benefits of Nanobubble Technology
The potential benefits of implementing nanobubble technology include:
- Reduction of unpleasant odors in water bodies.
- Lowering levels of E. coli and fecal coliform.
- Prevention of hydrogen sulfide production.
- Enhancement of resilience against contamination in aquatic ecosystems.
Case Study: Lake Elsinore
Councilmembers Steward and Kelly Purvis traveled to Lake Elsinore to examine a successful case study involving the use of nanobubbles. The lake had previously been burdened with severe pollution, which led to it losing its designation as a ‘lake.’ However, after the implementation of three barge-mounted nanobubble systems, water clarity improved, and algae blooms diminished significantly.
In 2022, Lake Elsinore faced a six-month closure due to toxic algae growth but saw transformative changes following a 2023 investment in nanobubble technology. The company chosen for this project, Moleaer, reported almost immediate improvements, revitalizing both wildlife populations and recreational opportunities, as observed by Councilmember Purvis during their visit.
Moving Forward in Coronado
Given the encouraging results from Lake Elsinore, Councillor Steward and Councilmember Purvis view the success of nanobubble technology as a promising option to explore for addressing water pollution in Coronado. Steward plans to continue her research into the viability of nanobubbles, focusing on how they could potentially be applied beyond Coronado to other cities facing similar sewage pollution challenges.
The Coronado City Council remains dedicated to ensuring clean water for the community. Nanobubble technology is being considered as a key facet of a broader strategy to combat the ongoing sewage crisis, demonstrating the council’s commitment to environmental stewardship and public health.
