Ice Melting Aeration

The Problem

Ice formation in cold climates can present problems including structural damage to moored boats, floating barges and dredges, dams, pilings, docks, and breakwaters.

The Nelson Environmental Solution

The primary mechanism for effective ice melting in a body of water is to mix slightly warmer, denser water from the bottom of the pond to the underside of the ice layer at the surface. This circulation or thermal de-stratification is achieved using either LINEAR or MAT fine bubble aeration.

In large ponds or lakes that have a significant bottom area, heat from the bottom soil is transferred into the water on a continuous basis. The aeration diffusers change the warm water density by introducing air into the water. This reduction in density combined with the pumping action of the bubbles produces optimum warm water circulation and subsequent ice melting.

In small or shallow water bodies, mixing creates full destratification and results in equalized temperatures throughout the body of water. Water and air scouring continues to reduce ice even after destratification occurs. This scouring action reduces the structural strength of the ice minimizing the potential of damage caused by ice pressure.


Ice melting with the LINEAR aeration system is extremely effective. Given sufficient water depth and volume, ice reduction rates of 1" per hour of operation are typically observed even at ambient temperatures of -30°C.
