Aeration and Mixing System

Submerged Aerators

Venturi-type submerged aerators ensure an efficient combined mixing and aeration action and they are especially suitable for homogenization tanks and storing water from the first rainfall.
They are made by connecting submersible pumps with power levels up to 30 kW to channel-type hydraulic units with large free passage combined with “OXY” series ejector devices.
OXY 80 and 150 units have a polyurethane (Vulkollan) diaphragm, easily replaceable without dismantling the pump from the ejector thanks to a patented system.
The OXY80 device has a flange suitable for connection to electric pumps having size 80 and 100 delivery ports.
For unbeatable versatility, Zenit has created three different product lines,called respectively:
• OXY
• SYSTEM OXY
• JETOXY

OXY submerged oxygenation systems are used in civil and industrial wastewater and sludge treatment plants, or whenever combined oxygenation and mixing are required. These systems can be installed without emptying the tank.
In OXY devices, the liquid conveyed is mixed with the air by the “Venturi” effect, creating a mixture containing medium-fine air bubbles that increase the contact surface area and provide highly efficient oxygen exchange.



JETOXY 50
JETOXY50 SYSTEMS comprise a Venturi-type ejector coupled to a submersible electric
pump rated from 0.37 to 1.5 kW with open multi-channel or vortex impeller.
JETOXY SYSTEM models can be selected on the basis of the performance curve best suited
to requirements, optimising consumption.
