Waste water treatment Aerators

Submersible Aerators

These radial submersible aerators represent a very flexible and versatile aeration system to be utilized in industrial water treatments and wherever the mixing process requires air introduction.

Homogenization and equalization, biological oxidation, sludge stabilization, flotation of grease are just some of the processes in which the radial aerators can be employed.

The S.C.M series is characterized by extended expulsion channels. These ducts are removable, and they are properly prolonged and shaped in order to increase contact time and area of influence.

Thanks to their solid structure, the submersible aerators can easily be installed and subjected to maintenance operations with no need to empty the tanks or stop the plants.

Surface Aerators

The low-speed aerators are suited to pump big water quantities with reduced absorbed power. They are mainly used in waste water treatment plants for biological treatment of wastes and in lagooning systems. ASP-F version has been created for stationary installations. This version is equipped with galvanized painted steel rotor, or, upon request, stainless steel rotor. The rotor may alternatively be made from fiberglass (ASP-V variant), reinforced internally by a steel frame. For installation in tanks or lagoons without a gangway or platform, or for variable liquid levels, the version for floating installation.

Submersible aerators Air-Get

The Air-Get system is based on the principle of coupling a submersible pump with one or more ejectors. Motor pumps with different power ratings and hydraulic properties may be coupled with ejectors with different flow rates so as to meet the demands of a wide range of applications. The liquid sucked by the pump is conveyed through one or more ejectors and this process causes a pressure drop that allows the air suction to occur through a pipe communicating with the atmosphere. The Air-Get system configuration allows this system to particularly be useful in case of oblong rectangular tanks and round or ring-shaped basins .
