|
| TWO SYSTEMS – MULTIPLE SOLUTIONS – ONE WAY TREATEMENT |
| |
| 1. THROUGH FLOW ELECTROLYSIS-ELECTROCLEEN ™ (ECS) |
| |
|
| |
|
Techcross Electro-Cleen ™ System (ECS) is one of the most effective ballast water
management systems utilizing electrolysis. ECS treats all incoming ballast water by
in-situ production of hypochlorite with combined effects of electric shock and hydroxyl radical in
the Electro Chamber Unit (ECU). This simple disinfection processing is so powerful
that it destroys cell membrane of microorganisms and prevents re-growth, needing only
one-time treat-ment. It means ECS contributes to reduction in time and operating
cost. Techcross has upgraded ECS through continuous research and development involving
and approvals with Classification Societies and Flag States to better performance.

2. Electro-Chlorination Technology – Slip Stream Method
Disinfection principle——Core technology
When seawater flows through the
electrolyzer, decomposition reactions take place on
the electrode surfaces, with chlorine produced at
the anode and hydrogen gas at the cathode. Chlorine
gas can be dissolved in water to produce
hypochlorous acid and hydrochloric acid rapidly:
|
Cl2 + H2O → HOCl + Cl- + H+
So the whole reaction is:
NaCl + H2O → NaOCl + H2↑
Sodium hypochlorite solution as a very effective
germicide can be kept in ballast water for a certain
period to effectively kill the plankton, spores,
larvae and pathogens contained in the ballast water.

ECS-HYCHLORTM
SYSTEM
TECHCROSS HYCHLOR ELECTROCHLORINATION – SIDE STREAM
DOSING SYSTEM
The
ECS-HYCHLORTM System adopts a disinfection technology combining
filtration with indirect eletrolysis. It consists of filtration, electro
chlorination unit and neutralization units with some of accessories.
The filter unit is mounted directly on the main ballast pipeline to eliminate
larger microorganisms and suspended solid than 50㎛
in size. The organisms and solids are filtered out by filtration unit and
discharged along with ambient water, using auto back-flushing function. During
de-ballasting, ballast water does not pass through the filtration unit.
The indirect electro chlorination unit operates only during ballasting to
disinfect microorganisms filtered out at first by the filtration unit. Only 1%
of total ballast water flows to the electro chlorination unit to be used to
generate the highly concentrated TRO. This concentrated TRO is injected to the
main ballast line to be mixed with the rest of ballast water and maintain
maximum TRO concentraion of 5.0mg/L.
The neutralization unit neutralizes the residual TRO by using sodium thiosulfate
as the neutralizing agent before discharging the treated water overboard during
de-ballasting. The maximum allowable discharge concentration of TRO is 0.1mg/L.
