voice This video is for providing an operation and installation for the Electro-Cleen System, the ballast water management system
developed by Techcross.
00:4 subtitl (title) Ballasting
8 e
voice ECS is one of the most effective disinfection systems using electrolysis. ECS treats one time at ballasting with certainty using a
simple composition of equipment – ECU, ANU, PDE, TSU.
01:0 subtitl ECU (Electro Chamber Unit)
3 e - Disinfects ballast water
- BASIC UNIT : 150B, 300B, 450B, 600B, 1000B
- CAPACITY : ~ 1,000㎥/h
- TYPE : ECU A / B Type, Ex-ECS A / B Type
- POWER CONSUMPTION : 3kW/100㎥/h (30psu)
voice ECU is the main equipment for disinfection of ballast water.
01:1 subtitl ANU (Auto Neutralization Unit)
5 e - Neutralizes TRO at discharge
- BASIC UNIT : 5000T, 10000T
- TANK CAPACITY : ~ approx. 200 Liter
voice ANU is designed to neutralize any remaining residual TRO prior to discharge. It is used during de-ballasting and stripping only.
01:2 subtitl PDE (Power Distributor Equipment)
6 e - Supplies power to ECS components and monitors the state of power supply in real-time
- BASIC UNIT : PDE12, PDE24
voice PDE supplies the necessary current to the chamber after converting 440V AC to DC depending upon the salinity of the water
enabling operational controls and facilitating ECS electrolysis.
01:3 subtitl TSU (TRO Sensor Unit)
7 e - Checks TRO values during ballasting and de-ballasting
- TYPE : TSU, Ex-TSU
voice TSU measures TRO concentrations during ballasting and de-ballasting to maintain the proper TRO concentration levels for efficacy
disinfection and neutralization.
01:4 subtitl FMU (Flow Meter Unit)
7 e - Monitors operation of ballast pump and allows ECS to operate upon ballasting
voice FMU is installed in between the ballast pump and inlet of ECU. It monitors operation of the ballast pumps and assists in the proper
functioning of ECS during ballasting.
01:5 subtitl T-Strainer
9 e - Protects ECU from sediment under 3mm
voice T-strainer helps to protect ECU from large sediment ensuring effective and efficient operation of ECS.
02:0 subtitl -
7 e
voice As the ballast water flows in the vessel, ECU is receiving the required current and voltage from the rectifier enabling them to
electrolyze the ballast water and kill micro-organisms by electrochemical actions.
02:1 subtitl ①Electric Shock ②OH- Radical ③Hypochlorite (02:26 부근에서 자막)
4 e
voice The electric energy and the production of oxidants such as hydroxyl radical and hypobromite which can oxidize cell membranes and
cell walls to disinfect organisms.
02:4 subtitl (title) Ballast Tank
1 e TRO (Total Residual Oxidants)
voice After treatment, the treated ballast water is stored in the ballast tank during the voyage. During this period, TRO, the residual
hypochlorite remains active in the ballast tank, preventing any re-growth of microorganisms for up to 30 days after treatment.
03:1 subtitl (title) De-Ballasting
4 e
voice ECS does not need to re-treat during de-ballasting. Before discharging the treated ballast water from the ballast tank, TSU examines
the TRO concentration.
03:2 subtitl (title) Neutralization
0 e
voice ANU doses sodium thiosulfate to reduce TRO value down to 0.1ppm before discharge. The neutralized water no more needs to treat.
03:4 subtitl (title) Various Installation References
6 e
voice Techcross provides various installation solutions for each project to meet the needs of the shipyards and the ship owners.
03:5 subtitl (title) 1. Tanker (On-deck Room)
0 e ECS in On-deck Room
voice This is one of the general installation references on Tanker. If there is no pump room but submerged ballast pump, you can make
safety room on deck. Explosion-proof type ECU and other equipments are installed in this room with skid-mount type; the other non-
explosive equipments in engine room for Aft Peak Tanks.
04:1 subtitl (title) 2. VLCC (Pump Room)
7 e ECU in Pump Room & Engine Room
Electronic Sub assembly in Foam Room
Voice If your vessel has both pump room and engine room, you can install Explosion-proof type ECU for ballast water in pump room and
non-explosive ECU for Aft Peak Tanks in engine room. At this time, electronic sub assemblies are in on-deck or foam room.
04:4 subtitl (title) 3. Tanker (Engine Room)
2 e Ex-ECU in Engine Room
Electronic Sub assembly in On-deck Room
voice Some Tankers which have no pump room but submerged ballast pump can install the non-explosive ECU in engine room with setting
an additional ballast pump. This design is possible because ECS does not require re-treatment at discharging. Even though the
additional will need to be added in the engine room, this is a much more economical solution.
