Open or Hybrid Scrubber System

Closed Loop systems are designed in accordance with the ships actual operational pattern (sizing of systems including tanks such as holding tanks and circulation tanks + residue)

Selecting a water treatment system

Technologies:

• Conveyor belts

• Ceramic filtration

• Multi layer filtration

• Centrifuges

• Combination of the above

Environmental considerations:

• What are the future limits for bleed off

• Bio Accumulative Substances

• PAH (Oil)

• Power consumption

• After treatment of residues (handling/storage)

• Type of coagulant and or flocculants + cleaning agents

OPEX versus CAPEX

• Low cost and high operation cost or ?

• EEDI/XI, CII

User friendly:

• Low maintenance

• Complexity – ease of use

• Reliability

• Training (“touch and go” crews)

• Easy to read manuals

Connectivity:

• Control system integration

• Realtime remote access

• Data logging & Reporting

Future:

• Upgrades to stricter regulation ?

• Scrubbers + Carbon Capture Storage CCS Technologies

• Fluid cleaning/filtration

• Still EGR systems
