Forward Osmosis pilot

Forward Osmosis pilot

The Convergence Inspector Forward Osmosis (FO) was developed to quickly evaluate the performance of forward osmosis membranes and processes. The unit includes an in-line chemical cleaning line that allows the user to perform cleaning studies, biofouling tests, fouling test, permeability tests and more. Furthermore, in-line conductivity sensors allow live measurement of retention.

Forward Osmosis pilot

The Convergence Inspector Forward Osmosis pilot system was developed to quickly evaluate the performance of forward osmosis membranes and processes. The unit includes an in-line chemical cleaning line that allows the user to perform cleaning studies, biofouling tests, fouling test, permeability tests and more. Furthermore, in-line conductivity sensors allow live measurement of retention.

The system can be customized to allow the user to perform Pressure Retarded Osmosis experiments. The system is designed with dual pumps; one for the feed solution and one for the draw solution. Thus flow and pressure of the feed and draw solution can be controlled separately.

The user-friendly software interface records flows, temperatures and pressures and allows the creation of individual test scripts. Whether you want to perform permeability tests with several different pressure or flux steps or simulate on-field operation with cleaning steps, the FO Inspector has you covered. It also allows automatic calculation of permeability, retention, TMP (trans-membrane pressure) and other user defined calculations. The system allows you to attach all kinds of flatsheet or spiral wound membranes and thus makes it extremely flexible.

The system is highly customizeable and can for example be designed to support pressures up to 69 bar, include additional sensors, in-line chemical dosing, in-line heating or automated recovery control and has many more options available.

Optionals:

  • In-line pH measurement
  • Customized flat sheet membrane modules
  • Customized flow- and pressure range (higher or lower)
  • In-line chemical dosing
  • Upgrade to chemical resistant Hastelloy/Duplex components
  • Heating system (includes heat exchangers and heating bath)
  • Feed & bleed recovery control
  • Pressure control of feed and draw solution
