Tank Mixing

Tank Mixing using Jet Mixers

Tank Jet Mixers are mass momentum exchange devices. They use pressurised liquid energy, provided by an external recirculating Pump, to entrain, mix and pump a secondary in-tank liquid, to achieve bulk mixing.

 

Importantly, our Tank Jet Mixers have no moving parts. This provides unrivalled reliability, giving you complete peace of mind.

 

Operators choose this reliable technology for many applications across multiple industries including;

 

 

This includes blending, solids suspension, dilution, heat distribution, pH control, temperature control and homogeneity.

Advantages of Tank Jet Mixers

No moving parts inside the tank

Virtually maintenance free once installed

Quick mixing times (3-Parts Suction within the tank to every 1-Part Motive fluid)

Custom designed to suit specific fluid properties and Tank geometry

Suitable for suspension of solids and mixing sludges

No limitation on tank size, multiple mixers can be installed

Can be ‘through-the-wall’ designs, so no access required for installation

Fast-track design, manufacture and deployment available

Tank Jet Mixers : Principle of Operation

In operation, pressurised motive liquid is discharged through the Jet Nozzle into the suction chamber. The change from pressure energy to kinetic energy (velocity) creates a region of low pressure that entrains liquid from within the Tank via open suction ports.

The motive and suction liquid streams combine and mix under high shear conditions in the Jet Mixer Diffusers and the resulting intimately mixed fluid is discharged into the bulk of the Tank liquid as high velocity turbulent jets.

Flexible Design & Layout Options

Each Tank Jet Mixing system is custom designed to suit the mixing requirements. We offer both single or multiple Jet Mixer arrangements, as required.

 

Transvac Jet Mixers are often supplied with an angle-creating, flanged spool to direct flow through a Tank wall or are mounted on an in-tank manifold to evenly distribute the mixing energy.

 

Standard Transvac Tank Jet Mixing systems entrain 3-parts suction liquid for every 1-part motive liquid.

 

The size, number of Jet Mixers required, and system layout depends on the Tank volume, mixing time, temperature, liquid compositions and mixing duty.

 

Transvac can supply Jet Mixers only with support spools or in-tank manifolds. Alternatively, Transvac can provide manifold designs, which can be made locally.

Typical Applications & Fluids

  • General Mixing / Blending
  • Municipal and Industrial Sludges – Digesters mixed to promote ideal process conditions. Pre and post digestion sludge holding tanks mixed to prevent stratification
  • Odour control – Municipal / Industrial sludge balance tanks mixed to prevent anaerobic conditions (optional atmospheric air entrainment to assist process)
  • Radioactive waste mixed on Nuclear Power stations and waste processing centres (exotic material used)
  • Mix corrosive / hazardous waste on effluent treatment plants
  • Homogenisation of epoxy liquid in paint production
  • Mixing of food products including wine, soft drinks, sauces etc
  • Blending of lube oils on petroleum plant
  • Blending effluent containing Glycol on pharmaceutical process
  • Neutralisation mixing duties using phosphoric, hydrochloric and sulphuric acids on water treatment
  • Agitation of resin beads for water treatment
  • Mixing styrene without generating static

Materials of Construction

Tank Mixers can be manufactured in virtually any material, carefully chosen to suit the process conditions;

 

  • Stainless steel
  • Carbon steel
  • Polypropylene
  • PVCu
  • PTFE
  • GRP

 

Hygienic designs are also available for the food / pharmaceutical industry as required.

Mixing proven through CFD

 

CFD modelling is perfectly suited to studies concerning Tank Mixing Solutions. Transvac can offer a detailed CFD analysis to optimise the arrangement of Jet Mixers in tanks to avoid fluid bypassing or stagnation.

 

Transvac can assess the quality of mixing based on various installation options, including manifold layouts; Jet Mixer inlet elevations; and angles. This is particularly beneficial for larger tanks where stagnation can be difficult to predict without CFD.

 

More complex studies can be undertaken focusing on the mixture’s physical properties as well as fluid concentrations.
