MAN Diesel and Turbo has granted approval for the Langh Tech water treatment system

Langh Tech is expanding its water treatment technology into new areas after working in close cooperation with MAN Diesel and Turbo.

It has developed a water treatment system to be used for cleaning the process water of Exhaust Gas Recirculation (EGR) systems.

In the EGR process, approximately one third of the exhaust gas is recycled back into the engine, first removing the particles from the redirected gases with a small scrubber. The process water from exhaust gas washing is continuously cleaned during EGR operation and this is where Langh Tech’s water treatment technology is applied.

The water treatment is based on membrane filtration, this means that the operational costs can be kept low and the waste consists only of small amounts of compact dry sludge.

First tests of the system were performed in Copenhagen in December 2015 using a small-scale prototype built into a container.

Since then, the process has been fine-tuned and Man Diesel and Turbo has granted approval for the Langh Tech water treatment system to be used in combination with the EGR process.
