Pompano Beach, Florida, October 19th: The City of Cape Coral has awarded Vertex Water Features of Pompano Beach, Florida a contract to install and test an AirGate bubble curtain system across the mouth of the Mandolin canal. The purpose of the bubble curtain is to block cyanobacteria in the river from entering and contaminating the Mandolin canal and its associated waterways.
Vertex AirGate systems have proven to be successful in Monroe County and highly effective in blocking floating seaweed and light debris from entering and polluting multiple Florida Keys canals, marinas and private dock areas from Key Largo to Big Pine. The application of this technology to block floating cyanobacteria blooms has not previously been attempted as it will be on the Mandolin canal.
Vertex Water Features has agreed to install and run the AirGate system for a three-week test period during which City of Cape Coral personnel will evaluate the system’s ability to block cyanobacteria from entering the canal. If the AirGate system proves ineffective in blocking cyanobacteria, the city may elect to extend the testing period or have Vertex remove the system and the city will not incur any costs.
The equipment includes a 12-horsepower compressor system that supplies air through hoses to forty-four membrane bubble diffuser assemblies lined up across the bottom of the 240-foot-wide Mandolin canal mouth. Air from the compressor system exits the membrane diffusers forming a wall of bubbles across the canal. This wall of bubbles pump water to the surface forming large boils, similar to a natural spring, of outward flowing water that provides the kinetic energy to push and deflect away floating cyanobacteria trying to enter the canal from the river.
Installation of the AirGate system is scheduled to begin Monday, October 22nd and be completed and operating by end of day Wednesday, October 24th.
