Clean Water Flux pilot

Clean Water Flux pilot

The Convergence Clean Water Flux (CWF) pilot system was developed to quickly measure water permeability through membranes at reproducible temperature and pressure. The CWF is used to quantify the permeability of microfiltration and ultrafiltration membranes. It is defined as the volumetric flow through a certain membrane area at a certain pressure.

Specifications

Feed flow range: 8 – 45 L/h
Pressure range: 0,1 – 16 bar
Pressure accuracy: < 0,1 %
Temperature range: 0 – 60°C
Dimensions: 40 x 21 x 29 cm

Clean Water Flux pilot

The Convergence Clean Water Flux (CWF) pilot system was developed to quickly measure water permeability through membranes at reproducible temperature and pressure. The CWF is used to quantify the permeability of microfiltration and ultrafiltration membranes. It is defined as the volumetric flow through a certain membrane area at a certain pressure. It can be used for example to quantify membrane performance before and after membrane fouling took place.

Before testing takes place a crossflow flush makes sure that no air bubbles are present on the membrane and complete wetting took place. Afterwards the system will provide a flow through the membrane at a constant pressure. The permeate flowrate is monitored using a high precision balance.

The system comes with an A7 flat sheet membrane module (membrane size: 50 x 80 mm), but fits all kinds of hollow fiber and flat sheet modules provided by the end user.

With the integrated touch screen the user can easily set up his own experiments.

Optionals:

  • Different flow and pressure ranges
  • High precision flowmeter
  • Flat cell closing system for fast replacement of tested membrane
  • Several membrane modules
