X-Flow

Compact 33

The Compact 33 is a tubular 5.2 mm ultrafiltration membrane very well suited for the separation of biological sludge or any other high solids application in which high effluent quality is required. Separating at 0,03 micron, this membrane filter allows only water and dissolved matter to pass, rejecting everything that is undissolved. The filtrate can either be used directly in many applications, or be fed into another (RO) treatment system to remove the dissolved matter. The construction of the Compact 33 allows for backflushing from filtration side to feed side, a cleaning process applied in various heavy-duty operations.

  • Tight cut-off at 0,03 micron
  • Applicable to total suspended solids levels up to 15 g/l biomass
  • High tolerance to hypochlorite cleaning
  • High flux rates 
  • Easily interchangeable
  • Also available with the X-Flow Helix technology, to  enhance flux and herewith performance by providing enhanced mixing and efficient removal of the cake.

Functional Description

for high solids applications

The Compact 33 holds 5.2 mm tubular UF membranes, capable in treating streams with solid concentrations up to 15,000mg/l. The module can be applied in a Crossflow configuration. With operations in the typical cross-flow mode, and given the limited capacity per module, multiple modules can be connected in series to create the required capacity.

Our engineers can support you in determining the ideal plant size, number of membranes, best setup and configuration for your specific purposes.

Fields of application

The Compact 33 finds its use primarily in the separation of oil-water mixtures from produced water and in high solids applications, such as separating clean water from biological sludge in membrane bioreactors (MBR’s). The filtrate will be free from solids of any kind and typically have an SDI of < 3, making filtration with the Compact 33 a good pretreatment method for Reverse Osmosis if all dissolved matter needs to be taken out.
The Compact 33 can be used for the following applications:
  • Sludge separation in Membrane bioreactors (MBR’s)
  • Produced water in oil & gas, mining, etc.
  • Purification of yeast solutions
  • RO pretreatment of feed waters high in suspended solids
