Spargers

Porvair offer a complete range of porous materials for gas/liquid contact applications across a variety of industries, including:

  • Food and beverage
  • Waste and water treatment
  • Chemical process
  • Pharmaceuticals.

As a manufacturer of porous media and elements, we are able to specify, design and manufacture the most efficient product for a given application.

The key to efficient gas transfer is to generate very high volumes of fine bubbles. It has been shown that a 1mm (0.04”) bubble has 6 times the gas/liquid contact than that of a 6mm (0.24”) bubble. Therefore, we recognise that bubble size is essential to optimise mass transfer and reduce gas consumption and energy costs.

Elements are available in Sinterflo® sintered porous stainless steel or Vyon® sintered porous polyethylene or Polypropylene.

Stainless steel spargers are supplied in stainless 316L and higher alloys such as Inconel® and Hastelloy® for very aggressive applications. Being manufactured from such resistant materials, Porvair spargers are cleanable and if necessary heat or steam sterilisable.

The elements are designed and manufactured from uniform, fine, controlled pore size media to achieve excellent performance in the distribution of a large number of small gas bubbles for a higher interfacial area. 

Typical applications

  • Intrusive and non-intrusive tangential pipeline spargers:
    • For the treatment of wastewater
    • Volatile stripping
    • Steam injection 
  • Tank spargers:
    • Fermentatio
    • Agitatio
    • Bioremediatio
    • Oxygen strippin
    • De-watering
    • Dissolved air flotation processes used by major oil companies 

Features and benefits

  • Rugged, fixed pore media.
  • Bubble size can be controlled by a wide range of available media pore sizes.
  • Temperature and corrosion resistant materials of construction.
  • High quality, all-welded, robust construction.
  • Higher diffusion rates from smaller sparging elements.
