At A&J Fabtech, we can offer picket fence thickeners in a range of high quality materials and sizes entirely dependent on your specifications. Experience in the water treatment industry and industrial processing that spans a quarter of a century ensures A&J Fabtech has the expertise to realise your optimum sludge thickening system.

Our picket fence thickeners utilise rotating blades of vertical rods with horizontal supports, which are driven via a central motor on a vertical axis to separate sludge and waste water to the tank bottom outlet and top sluice respectively.

We can provide a complete turnkey package for our customers that incorporates processing tanks, picket fence mechanisms, motors and all required access systems to enable a complete installation.

Standard sizes can be catered for between 1.6 metres and 16 metres in diameter, with larger diameters also available if required.

A&J Fabtech picket fence thickeners can be specified in various grades of steel including mild, galvanised and stainless.

Options for picket fence thickeners include:

  • Inlet diffusers
  • Scum control
  • Sludge blanket monitoring
  • Real-time sludge loading monitoring
  • Sludge feedback systems

Our dedicated design, manufacturing and installation teams can ensure short lead times for our customers. Installation times can also be minimised via pre-assembly and pre-wiring of picket fence thickeners, meaning less work is required to be carried out on-site. This can ensure that your new system is operational within the shortest possible timeframe from initial sign off.

We also offer electrical and mechanical testing of systems in-house, whether it has been manufactured by us or not.

Our engineers can also conduct site surveys to ensure the optimum design is created at the point of specification.

Expert maintenance teams are on hand to offer continued support throughout your assets operational lifetime. Furthermore, we can provide full refurbishment of equipment, irrespective of the original asset installer.
