scrufilter for effluent sludge

 

Effluent sludge

Need help with your septic tank conversions and sewage treatment options?


The Scrudrain sludge thickener

The Scrudrain sludge thickener improves upon conventional sludge thickeners by the use of an Archimedian screw, which has a polyester filter cloth attached, to form a drum with a screw inside. The rotation of the drum filter is achieved using an adjustable geared motor.

The filter cloth has a long life because it is not under tensile stress. The Scrudrain sludge thickener is supplied complete with control panel, washing pump, all ancillary items and are factory tested in order to minimise installation time.


Why use the Scrudrain for
sludge thickening?

  • Sludge with 0.5 – 3% dry solids can be thickened to 5 – 15% dry solids.
  • CE approved design manufactured using high quality AISI304 Stainless steel.
  • Variable rotation speed to control the concentration of the thickened sludge.
  • Can thicken up to 60m³ sludge per hour.
  • Low polyelectrolyte consumption.
  • The Scrudrain sludge thickener is supplied complete with washing pump and control panel, factory tested and ready to run.
  • 2 year warranty on all working parts.

The Scrufilter

The Scrufilter can be used to improve effluent sludge in many scenarios, including improving the discharge from sewage and effluent treatment plants, water recovery from industrial processes and filtration of surface water and well water.


Why use the Scrufilter to
improve effluent sludge?

  • Microfiltration for solids removal down to 20 microns.
  • CE approved, compact high capacity unit.
  • Flows up to 60 cubic metres per hour.
  • Range of screen sizes available: 20, 30, 40, 60, 80 and 100 microns.
  • Simple to install, no civil works required.
  • The Scrufilter is simple to maintain with screen plates can be changed insitu. Screens available in polyester and stainless steel.
  • 2 year warranty on all working parts.

How the Scrufilter works

See image to the right. Using a 40 micron cloth a reduction of 70 to 80% of the suspended solids is possible for the majority of tertiary treatment applications. The reduction in suspended solids is accompanied by a reduction in the COD, BOD5, phosphorus, nitrates and other substances. Custom designed filter sizes are available on request.
