- uniform flow through whole construction

1 Sparging with GKN sika porous metal:- uniform flow through whole construction - uniform small bubbles for effective gas transfer- long residence time of bubbles in liquid- high contact area gas / liquid- reduced dissolving time for gas in liquid- reduced gas quantities forequal results ( drilled pipes)- 100% seamless construction for best corrosion resistance- easiest installationGKN spargers are available in several stainless steel alloys (standardis AISI 316L) as well as in nickel based alloys or titanium. Pore sizes from - 200 m are available. All spargers come together with customer designed connection, readyto be serves- Food and beverage industry- Pharmaceutical industry- Chemical & industrial industry- Pulp and paper industry- Petrochemical industryWith applications like:- Aeration - Agitation - Bioremediation - Carbonation - Chlorine bleaching - Column flotation- Dewatering - Fermentation - Gas/liquid reactions- Hydrogenation - Oil flotation - Oxygen - Oxygen stripping- Oxygenation - Ozonation - pH control- Steam - Volatiles stripping Dynamic (in-lline) spargers Working principle: gas is pumped through a porous sika IS tube direct in to the the velocity and turbulence of the flowing liquid, dynamic sparging is one of thecheapest and most efficient sparging systems.

2 Due to the shear effect, extremely smallgas bubbles are separated from the porous tube additional improvement of gas dissolving manifold construction (similar to cross flowfiltration units) are (tank) spargersStatic sparging is usually used in batch productions and / or lower quantities of liquids. Designs with only one sparger aswell as christmas tree shaped manifold designs are offers also the new seamless bended tube down to 400 mm diameter! Therefore also areas close to tank walls can besparged with one spargerExample with three spargers(christmas tree)Example with a bended tube(close to tank walls) ! " !
