Floating aerators are secured using robust anchoring systems. In most installations, the unit is anchored using anchoring rope connected to a heavy concrete anchor positioned at the bottom of the water body.
Depending on the water body’s dynamics and edge layout, units can alternatively be tethered from the side bank using tension lines attached to a durable galvanised MS structure.
The anchoring system prevents the aerator from drifting freely while still allowing it to accommodate changes in water level. The exact arrangement depends on the site’s depth, water movement, and operating conditions.
Our floating wetlands are anchored to prevent them from drifting excessively across the water body. Depending on wind patterns, currents, and lake geometry, they are either secured to the bottom bed using anchors with flexible marine ropes, or tethered to the shoreline via structural tension lines.
Anchoring is particularly important because, as water levels fall, an unanchored floating wetland can drift toward the shoreline and eventually become grounded. Once grounded, it may no longer remain fully afloat.
We therefore generally recommend anchoring the floating wetland in the deeper section of the water body, where it can continue to float even when water levels fluctuate.
Aerator placement is site-specific and depends on the size, shape, depth, pollution sources, water movement, and existing dissolved oxygen conditions.
Where possible, aeration near the inlet or the point where polluted water enters the water body helps begin oxygenation early. Aerators are also effective when placed near dead or stagnant zones and corners.
For symmetrical water bodies, a central position works well. For long, irregular, or kidney-shaped lakes, deploying multiple staggered units ensures uniform circulation.
The final placement should therefore be determined based on the specific characteristics of the lake or pond, with the objective of improving circulation and minimising stagnant or oxygen-depleted dead zones.
Floating aerators require adequate water depth to operate safely without disturbing the bottom sediments.
We generally require a minimum installation depth of approximately 4 to 5 feet from the water surface to the bottom. This prevents the high-velocity jets from drawing up mud, clay, or sand, which can cause cloudiness and wear down the internal machinery.
If a water body becomes shallower than the recommended operating depth, the aerators should be switched off until adequate water depth is restored.
The required operating time depends on the water body’s size, pollution load, dissolved oxygen levels, aerator capacity, and other site conditions.
As a general operating range, our systems are typically run for approximately 6 to 8 hours per day. For general lake management and aesthetic upkeep, 10 to 16 hours a day is also common.
For severe lake remediation, wastewater pre-treatment facilities, or heavily polluted urban drains, continuous 24/7 operation may be recommended for optimal water health.
Automatic timers in the control panel can be used to manage the operating schedule.
If you are running the system on a restricted schedule, night-time operation is critical.
During the day, aquatic plants and algae produce oxygen through photosynthesis. At night this process reverses and they consume oxygen, causing dissolved oxygen levels to crash just before dawn. Running the aerator at night prevents these dangerous oxygen dips.
