  • Fluid Substances
  • Water and/or Similar Liquids.

What is used for : to Transfer Oxygen and Ozone

The Static Diffuser OXY – 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 .

No Contamination – Better Mixing – Higher Efficiency

The OXY – 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

TECHNICAL CARACTERISTICS of the Oxygenator by PE

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 – helier 4” – hsp 4″ – – and the helier 12” structured packing – helier 12” – hsp 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

see the experimental data reported in the  helier Book whose values were obtained through the experimental research carried out at the University of Pisa , by the Equipe, under the coordination of Prof Nardini, Prof Paglianti and  Dott.ssa Brunazzi.

The helier 4” structured packing is assembled 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 the Oxygenator by PE are to be installed.

Oxygen Transfer: the OXY and the Fermentation Process

The OXY – 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 Reactor
–   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 a velocity for Oxygen Transfer

 

The Design Procedure foresees to choose :

► the Type of the Equipment to be Used          (4 ELEMENT – 5 ELEMENT – 7 ELEMENT Diffuser )
► the Number of Equipment to be Installed    ( of OXYGENATOR)
► the Disposition inside the Reactor                   ( 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  OXY – Oxygenator by PE Static Diffuser and the optimization of its use in the Fermentation Processes are achieved when the Oxygenator by PE is combined with a Proper Bio-Chemical Fermenter , porposely designed for .

Ozone Transfer : the OXY and the Water Disinfection

The OXY – 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 be 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 :

  • Optimize the Transfer Process

Oxygenator by PE : Materials and Product Data Sheet

In accordance with the usual requirements of the Process to transfer oxygen and/or Ozone , the Oxygenator by PE Static Diffuser is built with Proper Materials .

For the above Application the following MATERIALS have been chosen :

–   Structural Part           =   SS AISI 316 L
–   Structured Packing    =   from   HDPP   to   PPS

Hereby we report the  Equipment Data Sheet  of the Static Diffuser we design , build and supply . The Main TECHNICAL PROPERTIES are reported .

Oxygenator by PE : an “ad Hoc” Design

Either in the case of Oxygen Transfer for the Fermentation Process and in the case of Ozone Transfer for the Water Purification , for each Client Application  we study and design the best solution to :

–   comply with the Technical Specification received by the Client
–   optimize the Process Step

for which we choose the most suitable OXY – Oxygenator by PE .

Hence the Oxygenator by PE Static Diffuser is an “ad Hoc” Product and constitute an “ad Hoc” System that must be  :

  • sized
  • designed

case by case and application by application .
