EcoGuardian BWTS

General Information

Hanla IMS Co.,Ltd has developed eco-friendly EcoGuardian system for treating Aquatic Invasive Species in a ship's ballast water. Treatment method is side-Stream type which enables the system to be remotely installed away from the ballast lines. The EcoGuardian system can be installed separately by unit. So relocation of other equipments and additional engineering can be minimized.


Treatment Method :

Ballasting [ Filtration + Electrolysis (Side-stream) ]
De-ballasting [ Neutralization ]

Biological Efficiency :

Compliance with IMO D2 performance standard

Utility Required :

Control air [6-7 kgf/cm2] for pneumatic valve
Fresh water for rectifier cooling

Installation Type :

1. Skid mounted / 2. Containerized / 3. Separate

EcoGuardian Key Features



Automatic backflushing filter unit removes large organisms.

Automatic backflushing operation starts when the pressure difference between the water inlet and outlet reaches a certain value.

The side stream of the ballasting water goes through the electrolysis unit that generates the high concentration of TRO (Total Residual Oxidants). The consentrated stream is then injected back to the main ballasting line.

Electrolysis unit (including electrolytic cells, rectifier/ transformer, booster pumps, conductivity sensor and degassing devices) produces sodium hypochlorite solution in situ which disinfect the residual planktons, pathogens, larva or spores.

Neutralization unit adds sodium thiosulfate solution into the treated ballast water to neutralize the residual TRO during de-ballasting.

Control system including PLC, HMI and auxiliary equipment.
