Ballast Water Treatment

BIO-SEA Ballast Water Treatment

Global Electrical Solutions is turnkey partner for BIO-Sea Ballast Water Treatment Systems. The ballast water treatment system BIO-SEA combines mechanical filtration and high UV dose disinfection, without any chemical treatment, made with high marine quality components.


BIO-SEA systems are IMO and USCG type approved. Global Electrical Solutions has equipped many vessels with BIO-Sea systems, as well as for new building projects and turnkey solutions for retrofits projects, from onboard study till onboard installation (at quay, dry-dock or on voyage).

Best Technology

BIO-UV Group has more than 18 years of experience in UV technology (swimming pools, municipal, drinking water, aquaculture, waste waters, REUSE, ballast water treatment, etc.) ensuring optimum design and reliability.


BIO-UV Group designs and manufactures UV systems at its facility in France to maintain a high level of quality and efficiency and keep full control of the total production chain.


BIO-SEA is safe: being chemicals free, without explosive gases, zero by-product, zero active substances and zero induced corrosion in the pipes or in the ballast tanks.

Best Service

GES together with BIO-UV Group provides full support to the ship’s crew for complete understanding of the system - from detailed documentation to tailored servicing.


Our Service team remain available during and after the integration process.


We offer many training programs from face-to-face training during commissioning to the first ballast operation, or a multi-level computer-based training program (CBT). We also welcome to the training facility of BIO- SEA in France were ship-owners technical superintendents, crew and other stakeholders involved in the operation of our BWTS for hands-on real-operations training.

Best Performance

BIO-SEA is IMO and USCG certified, tested by first-class laboratories (DHI, NIVA). Due to the superior performance, BIO-SEA has the best UV USCG type approved system on the market with 0 hour holding time for fresh water (no holding time), and 24 hours for marine water at full flow.


BIO-SEA maintains top efficiency even with low water transmittance.


BIO-SEA systems are made with high quality materials (titanium, copper aluminum) and components from reliable and recognized European suppliers. We are providing the BWTS with the longest lifetime on the market.

Easy to use & maintain

BIO-UV Group offers ready to use and complete solutions.

The treatment process is fully automatic – there is no manual intervention required: easy to operate with low maintenance, the large touch screen simplifies the HMI.


BIO-SEA, thanks to the different communication protocols available (dry contacts, RS 485, auxiliary touch screen) can be fully integrated to all ship automation systems.


System design reduces moving parts (as well as onboard spare parts), which results in lower operational maintenance costs.


BIO-SEA UV reactors work independently, allowing the system to stay operational should one of the reactors require maintenance.
