88% Reduction in Total Suspended Solids - LG Sonic

Data-driven technology

The Quiport International Airport, Mariscal Sucre, has a reservoir built to control the runoff generated by rainwater, and the capacity to retain a storm with a return frequency of 100 years.

Previously, the reservoir had a problem with excessive algae growth, increasing PH levels (<7) as well as organic matter levels. This made it attractive for the wildlife found in the ecosystem adjacent to the airport, which represented a risk to the aerodrome’s operational security (a danger of impact between the wildlife and the aircrafts), for which it was necessary the use of chemical products (algaecides), to maintain partial and temporary control.

MPC-Buoy installed in the Quito airport reservoir.

In 2015, a study of options for algae control considered the MPC-Buoy system as the best choice because it provided a long-term solution and a low environmental impact since it does not generate hazardous waste or health risks for operators. Since the installation of the LG Sonic ultrasound units in early 2017, the use of chemicals has been significantly reduced, which it also reduced the manpower and hours of work required to control the algae.

The use of this system also allowed to keep a real-time record of the water quality parameters, observing a reduction of 88.36% in the total solids and therefore also the turbidity of the water body, additionally a significant reduction in algae on the surface in sample analysis.

“Regular monitoring of the rainwater reservoir shows a positive impact of the MPC-Buoy system on algae control and improvement in water quality“.
