Oxygenator - Diffuser of Oxygen (O2) and Ozone (O3)

The Static Diffuser “Oxygenator by PE” is used for

• Oxygen Transfer
• Ozone Transfer

in the Industrial Application and in the Process Steps, where the above elements are required and/or necessary and there is the presence of a fluid level. 
Usually to get the Transfer of Oxygen and/or the Transfer of the Ozone equipment with mechanical moving parts are commonly used, such as:

• Agitators with Nozzles
• Pale with Nozzles

and/or Similar Equipment.

The “Oxygenator by PE” Static Diffuser is free of any mechanical moving element, which permits:

• to Avoid the Contamination from the Mechanical Moving Parts
• Not to Maltreat the Fluid / Broth where these substances must be transferred
• to get Lower Energy Consumption
• to be Spare-Parts Free
• to be Maintenance Free to get a Better Mixing of the Fluid / Broth, while achieving the transfer of the Oxygen and/or the Ozone required by the Process Step

In accordance with the application, to get good Transfer Coefficient for the Oxygen and the Ozone we have chosen to apply our helier 4” structured packing - hsp helier 4” - and the helier 12” structured packing - hsp helier 12” - which have the following properties:

• High Specific Area (ASPEC = m2/m3 )
• Very Low Specific Pressure Drops (Delta P = mm H2O/m )
• NO ENGULFING VELOCITY no engulfing

Whose values were obtained through the experimental research carried out by the University of Pisa by the Equipe, under the coordination of Prof Nardini and Prof Paglianti)

The helier 4” structured packing is assembled so to build a “column” of different height, such as:

• with 7 ELEMENTS h = 0.8 m (Commercial Code = OXY 4” 7EL)
• with 5 ELEMENTS h = 0,6 m (Commercial Code = OXY 4” 5EL)
• with 4 ELEMENTS h = 0,5 m (Commercial Code = OXY 4” 4EL)

The helier 12” structured packing is assembled so to build a “column” of different height, such as:

• with 7 ELEMENTS h = 2.1 m (Commercial Code = OXY 12” 7EL)
• with 5 ELEMENTS h = 1,8 m (Commercial Code = OXY 12” 5EL)
• with 4 ELEMENTS h = 1,5 m (Commercial Code = OXY 12” 4EL)

This “column” includes

• a proper bracket system
• a support plate

for the anchorage in the Basin

• the Reactor
• the Fermenter / Digester
• the Lamination Basin with Laminar Flow
• the Post-Aeration Channel of the WWTP and/or the Aerated Lagoons
• where “Oxygenator by PE” the must be used.

The “Oxygenator by PE” Static Diffuser has been created, thought, designed and built to be installed Inside the Fermenters
with the precise aim to supply the Oxygen Required by the Fermentation Process

• Optimizing the Transfer Process
• Minimizing the Reactor’s Stop-Time for Maintenance
• Cutting the Contamination from the Mechanical Moving Parts
• Up-grading and Getting Uniform the Fluid Mixing inside the Rector
• Cutting the Cost of the Oxygenation Operation / Step

On the basis of the Technical Specifications given by the Client and/or the Plant Operator, information such as:

• Internal dimensions
• net available height
• liquid depth of the Broth / Culture Liquid
• available internal diameter
• operating conditions, in terms of Temperature (T in °C) and Pressure (P in bar )
• quantity of Oxygen to be Transferred
• request velocity for Oxygen Transfer

The Design Procedure foresees to choose:

• the Type of the Equipment to be Used (4 ELEMENTS 5 ELEMENTS 7 ELEMENTS Diffuser )
• the Number of Equipment to be Installed (Nº of OXYGENATOR)
• the Disposition inside the Reactor (Nº of RAWS)
• the proper Geometry to Distribute the Equipment inside the Fermenter (Distribution Geometry)

so to

• comply with the Technical Specification of the Client
• Optimize the Fermentation Process.

The best performance by the “Oxygenator by PE” Static Diffuser and the optimization of its use in the Fermentation Processes are achieved when the  “Oxygenator by PE” Static Diffuser  is combined with the Proper Bio-Chemical Digester

GG - Great Giò  that is, actually, in the development phase by PE Technicians.

The “Oxygenator by PE” Static Diffuser has been thought and designed for the  Ozone Transfer  inside the

• Hydric basins
• Water Tanks
• Post-Depuration Basins of the Waste Water Treatment Plant
• Post-Aeration Channels of the Waste Water Treatment Plant
• Channels with Fluid Laminar Flow

where it is necessary to:

• Disinfect the Water
• Sanitize the Water
• get Potable Water

so that the final water can used by human beings and/or by the animals of the animal breeding. 

On the basis of the Technical Specifications supplied by the Water Client and/or the Plant Operator, process engineering parameters such as:

• Internal dimensions of the Basin / Channel / Water Pipe of the Municipal Water System
• Water depth
• Working conditions, in terms of Temperature (T in °C) and Pressure (P in bar )
• quantity of Ozone to be Transferred

The Design Procedure consists in the choice of

• the Type of the Equipment to be Used (4 ELEMENTS 5 ELEMENTS 7 ELEMENTS)
• the Number of the Equipment to be Used (Nº of OXYGENATOR)
• the Disposition Inside the Basin / Tank / Channel (Nº of RAWS)
• the Geometry of the Equipment Distribution (Distribution Geometry)
• so to
• respect the Technical Specification of the Client
• Optimize the Transfer Process
