Floating surface aerators are secured using a:

• A. Power cable
• B. Guide wire
• C. Discharge guide
• D. Draft

Answer: (B)

Floating surface aerators stay in place by a tether called a guide wire mooring that runs from the float to a fixed anchor. This setup keeps the aerator at a set radius, resisting wind, currents, and wave action so mixing remains even and the unit won’t drift into other equipment. The power cable merely supplies electricity and isn’t meant to secure the unit; the discharge guide directs flow, not anchoring; and draft isn’t a standard method for securing floating equipment. Using a guide wire is the proper way to maintain position and safe, reliable operation.
