bw-monitor gives you full supervision of the (de)ballasting process

With IMO’s ballast water convention (BWM/CONF/36) entering into force relatively soon, many ships will need to install a ballast water treatment system (BWTS). Ballast Water Monitoring A/S has decided to develop a monitor, which determines the efficacy of these systems in an in-line, on-time and reliable manner.

bw-monitor is developed in order to supervise the ballast water treatment system on board and give an alarm in case of malfunction. It is designed to monitor two positions before and after the filter and the disinfection unit.

In principle, viable organisms are detected according to a fluorescence signal from chlorophyll, which is detectable directly in the ballast water stream without chemical addition or extracted sample manipulation. Additionally, an indication of the presence of larger organisms is provided by a laser diffraction signal on the density of particles before and after the filter.

bw-monitor’s design

Design Description:

Excitation 430 and 460 nm
Emission 680 nm
F0 and Fmax is measured

Laser 650 nm
Power 230 VAC
Measuring frequency for fluorescence 8 kHz
Measuring frequency for laser diffraction 37 kHz

A measuring cycle takes around 0.5 sec and measures minimum fluorescence (F0), maximum fluorescence (Fm) and light scattering.

bw-monitor comes with intuitive software

The software has been specially designed to run on the PC that comes with bw-monitor. It will indicate the current state of the filter and disinfection system.

Moreover it will log the data, encrypt them and send to bwm-Cloud, and prepare the custom status rapport for the Captain after each (de)ballasting process.

Our mission is to build confidence in ballast water treatment.

The bw-monitor checks the performance of your ballast water management system. The bw-monitor continuously samples in the ballast line and provides data to you – immediately and independently: no interaction is needed from your crew.

The bw-monitor uses laser and UV fluorescence to detect particles and to monitor the viability of phytoplankton. Real-time, indicative compliance data can be followed both onboard and ashore, and all data can be logged for future inspection.
