Case study: Aeration

Water Utility companies and major airports

The challenge

Waterbodies support aquatic life which is dependent upon oxygen within the water to live. Oxygen levels can be depleted in waterbodies by events such as pollutions or algal blooms.

Depleted oxygen levels can lead to damage to the aquatic life including fish deaths, this in turn leads to regulatory enforcement action, financial penalties and reputational damage.

The solution

There are two principal methods of aeration that can be employed to boost oxygen levels in a waterbody, chemical aeration and mechanical aeration. Our water quality experts will determine the most appropriate aeration solution through consultation with our client and key stakeholders including the regulator.

Mechanical aeration solutions may include deployment of venturi, splash and compressor based bubble solutions. Chemical aeration solutions will include regulated dosing of the waterbody with hydrogen peroxide (H2O2).

The results

A chemical dosing operation can be completed within several hours and will result in an immediate and sharp boost to the oxygen level in the waterbody, the elevated oxygen level can then be monitored to ensure full recovery.  Mechanical aerators can equally be deployed within a few hours and will gradually increase oxygen levels in the waterbody and can remain in situ to help to sustain the elevated oxygen levels.
