The Convergence Inspector Membrane Distillation pilot was developed to evaluate the performance of membrane distillation processes. It is suited for direct contact membrane destillation (DCMD), air gap membrane destillation (AGMD) and vacuum assisted membrane distillation (VAMD). Also standard multifunctional membrane destillation cells can be delivered with the system.

The Convergence Inspector Membrane Distillation pilot was developed to evaluate the performance of membrane distillation processes. It is suited for direct contact (DCMD), air gap (AGMD) and vacuum assisted membrane distillation (VAMD).
It consists of two circulating loops of fluids, one hot and one cold. Inside a membrane module both streams are in non-wetting contact with the membrane. The temperature difference between both sides induces a partial vapor pressure gradient. The membrane lets certain compounds diffuse which condensate again on the cold side. Two balances placed at both feeds allow the calculation of permeation rates. The system comes with a flat sheet membrane module that can be used in direct contact or air gap method configuration.
The setup comes with isolated tubing that allows both feed streams to be circulated with minimum heat loss. It is also equipped with plate and frame heat exchangers and can be connected to any heating or cooling bath (baths are optionally available).
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 at several different flow or temperature steps the MD Inspector has you covered. It also allows automatic calculation of permeability, TMP (trans-membrane pressure), temperature gradients and other user defined calculations. The system allows you to attach all kinds of modules and thus makes it extremely flexible.
The system is highly customizeable and can for example include additional sensors, in-line chemical dosing or vacuum assisted permeation for vacuum membrane distillation (VMD) and has many more options available.
