Langh Tech launches ballast water treatment system
A Finnish shipowner, operator and marine engineering group has launched an inhouse-designed filtration and UV- based ballast water treatment system
The newly launched Langh Tech LanghBW600 ballast water treatment system (BWMS) has been retrofit installed, without drydocking, on 2007-built, 907-TEU feedermax container ship Linda.
In a livestream presentation from the vessel, Langh Tech chief commercial officer Laura Langh-Lagerlöf introduced the new BWMS, which consists of a UV treatment system, Hydac filtration system and a simple-to-use operating system.
“The system has been running for a month on Linda with very good experiences,” said Ms Langh-Lagerlöf.
Langh Tech product manager Kim Tervonen was on hand to present some of the finer details.
The installation on Linda appeared to be extremely compact, which will appeal to those operators of similar size vessels. Features include an independent cooling system so that it can be placed in standby mode if cargo operations are halted, and the slide out reactor array, allowing easy access for cleaning without interfering with the wiring.
“Extremely easy and simple and does not take much time or effort,” commented Mr Tervonen on the lamp cleaning process.
Each reactor array can process 300 m3 per hour. For high flow rates, more reactors can be added in parallel. A boost pump can be fitted to ensure pressure and a back-flush pump can be fitted, too.
The system does not require any hold time when operating in IMO areas, said Mr Tervonen.
Mr Tervonen noted that the 20 micron Hydac AUTOFILT RF14 filter is working well and to specification. “We have not been able to clog the filter a single time,” said Mr Tervonen.
The LanghBW600 has completed land-based testing and is currently being Independent Lab (NIVA) tested and undergoing classification by DNV with a view to receiving IMO and USCG type-approval in early 2022.
