Visit site
Rotex brush aerators are horizontal-shaft surface rotors used for oxygen transfer and directional mixing in wastewater treatment. Aerators are commonly custom-designed for installation in existing oxidation ditches or to replace ageing equipment to improve oxygen transfer and mixing efficiency. Rotex brush aerators are efficient aerators with a standard aeration efficiency of 2.0kgO2/kWhVertex low-speed surface aerator
Visit site
Vertex low-speed surface aerators offer constant efficiencies over the entire lifetime of the system, which can often be up to 30 years. They are suitable for a wide range of applications including tanks of any shape and size, oxidation ditches, MBR and SBR systems, lagoons, ponds, mixing tanks and buffer tanks. They are designed so that the
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

SFA enviro
Manufactures floating and fixed aerators, decanters and mixers for sale or hire. Aerators work on the basis that liquid is aspirated via the suction cone and is pumped axially up through the cylindrical volute, after which its flow is bent from axial to radial, ensuring that maximum kinetic energy is transferred to the water surface. Also offers a
