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

Potentially the most efficient method
of hypochlorination is the production on
demand of sodium hypochlorite in situ,
electrolytically, through use of a concentric
tube electrode (CTE). This hypochlorination
technology is known in the maritime industry
as the Chloropac system and is produced by
Siemens Water Technologies.
