HS-OWS-5

Hansun Marine HS-OWS-5 is a marine oily-water separation system. It is normally installed in the engine-room bilge-treatment area between bilge holding arrangements and the approved recirculation or discharge piping. Its primary purpose is to remove oil from contaminated bilge water before any permitted overboard discharge. Unlike ordinary settling equipment, this system is integrated with oil-content monitoring and automatic stopping or recirculation functions required for compliant operation. The supplied record already contains the available concise model or rating information, so those existing figures are not duplicated here and no additional meaning is inferred from the model code. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Coalescer, filter or separation-stage fouling reduces separation efficiency and causes rising oil-content readings or automatic recirculation
Oil-content monitor contamination, blocked sampling lines or calibration drift produces unstable readings, alarms or discharge shutdown
Diverting-valve, solenoid or actuator faults prevent correct recirculation and cause sequence alarms
Feed-pump seal wear or suction-side air ingress causes unstable flow, poor treatment performance or visible leakage
Detergents or stable emulsions in bilge water overload the separation process and cause persistently high oil-content readings

Service & Maintenance

Inspect separation stages, filters, coalescers, pumps, monitor sample lines, automatic stopping devices and overboard valve arrangements. Verify that the approved treatment route cannot be bypassed and review operating records where required. Clean and check the oil-content monitor according to the approved procedure. Refer to the manufacturer documentation for the exact figure for flow, pressure and calibration criteria.
