SiCURE<br />
Siemens 2 7<br />
The SiCURE ballast water management<br />
system from Siemens uses a combination<br />
of physical separation and a proprietary, ondemand<br />
treatment with biocides, produced<br />
in situ from seawater, without <strong>the</strong> addition<br />
of chemicals. The system is based on three<br />
phases: filtration, electro-chlorination, and<br />
demand-regulated control logic.<br />
The main functions of <strong>the</strong> filter in <strong>the</strong><br />
SiCURE system are to remove or break<br />
larger organisms using a 40µm weave wire<br />
screen, and to provide reliable, non-stop<br />
operation at high sediment loads while<br />
minimising backwash flow. The biofouling<br />
control provided to <strong>the</strong> filter assures<br />
its reliable function and minimises<br />
maintenance requirements of<br />
<strong>the</strong> system.<br />
For electro-chlorination,<br />
SiCURE oxidises and<br />
eliminates aquatic<br />
invasive species<br />
(AIS) with sodium<br />
hypochlorite (NaOCl).<br />

and heat transfer systems of land-based,<br />
offshore and shipboard installations.<br />
Potentially <strong>the</strong> most efficient method<br />
of hypochlorination is <strong>the</strong> production on<br />
demand of sodium hypochlorite in situ,<br />
electrolytically, through use of a concentric<br />
tube electrode (CTE). This hypochlorination<br />
technology is known in <strong>the</strong> maritime industry<br />
as <strong>the</strong> Chloropac system and is produced by<br />
Siemens <strong>Water</strong> Technologies.<br />
