UV BWMS 6000m3h ABS-approved
Wärtsilä Ballast Water Treatment Systems. The Wärtsilä Aquarius product line comprises ballast water treatment systems with two main technologies: UV-based systems (Aquarius UV/UVX) with filtration + UV irradiation and electro-chlorination (Aquarius EC) with filtration + side-stream electrochlorination. Both systems are approved for IMO MEPC.300(72) and USCG certification. The systems enable

Common failures & inspection points
Quarterly cleaning of quartz tubes, annual visual inspection of UV lamps, verification of UV intensity measurements by calibrated sensors, documentation of operating hours
Differential pressure sensor functional test (should automatically trigger backflush cycle at approx. 0.3 bar), visual inspection of filter element for damage/blockage, verification of differential pressure after backflushing (should reach < 0.1 bar)
Annual sensor calibration (preferably by manufacturer), metric verification of measured UV intensity against reference values, isolation test of sensor against environmental influence, verification of alarm thresholds and signal transmission
Verification of total residual chlorine (TRO) after treatment (must remain ≤ 0.1 mg/L), visual condition of EC cell for corrosion/wear, verification of static mixers for blockage, measurement of voltage ratios at EC electrodes
Functional test of automatic backflush valves (should respond reliably to sensor signal), visual inspection of all hydraulic lines and connections for leaks, verification of pump pressure regulator, flow rate verification against manufacturer specification
Verification of valid type approval certificates (IMO MEPC.300(72), USCG), control of ballast water record book with current entries, verification of conducted biological commissioning tests (required from 01.06.2022), verification of maintenance protocols and service records
