Spiral aerators provide efficient aeration with strong directional mixing in wastewater treatment systems.
They are particularly useful in emergency situations where other aeration plant has broken down or needs supplementing, and where horizontal flow is required, such as in oxidation ditches and aerated lagoons.
Spiral aerators have been used in a wide range of applications, from polluted surface water lagoons at several major UK airports to large oil refineries, and from sewage works to landfill leachate lagoons.
Mounted on GRP floats, the aerators are perfectly suited for lagoons and tanks with fluctuating water levels.
A bracket-mounted option is also available for mounting to bridge structures or tank walls where the water level is constant.
Spiral aerators do not have any submerged bearings or couplings, which are the traditional source of maintenance problems. Only stainless steel and GRP components are used below water level.
Their reliability and low-maintenance design makes them suitable for remote and unmanned sites.
