Langh Tech has launched a new generation of water treatment system upgraded with new membrane technology to increase water cleaning capacity.

The new type of membrane filter element provides a 50% increase in water cleaning capacity compared to the previous elements, without increasing the size of the water treatment units.

This system has been tested onboard Langh Ship’s M/S Marjatta since the first half of 2017 with test results confirming that water cleaning capacity was increased by 50% without compromising any other system parameters.

On the market

Langh Tech said that the first set of second generation systems have already been delivered to a customer.

This second-generation water treatment system is available for both exhaust gas recycling (EGR) and SOx scrubbers and is suitable for sea water, as well as fresh water systems.

The Langh membrane filtration technology was initially developed by Industrial and Ship Cleaning Services Hans Langh, for purifying dirty wash water.

Langh later developed the membrane filtration-based SOx scrubber closed loop water treatment system and installed the first unit onboard a multipurpose vessel in 2013.

Since then, the company has been installed on fifteen vessels, with installations to an additional six vessels currently in the pipeline.

In 2015, Langh Tech tested the water treatment system with EGR scrubber water at the MAN Diesel & Turbo premises in Copenhagen.

The water treatment system has been granted MAN Diesel & Turbo approval which states that the Langh Tech water treatment system technology is applicable for two-stroke EGR.
