Marinfloc

Since the start of Marinfloc in 1994, they are the leader in innovative systems for treatment of waste water on ships and offshore units. The treatment equipment include bilge water, drill slop, black and grey water and oily sludge. The success of Marinfloc is found in their knowledge and long experience in marine engineering. They take pride in the fact that all Marinfloc technology is thoroughly developed on board ships and offshore installations to meet onboard conditions and not just to fulfil regulations that do not mirror reality. To clean water Marinfloc use the flocculation technology as it is proven to be the far most effective method. The effluent water quality from all our treatment units supersedes all current regulations.

All our equipment is fabricated in Sweden at our factory in Varekil to meet the highest quality standards and we only use top quality components and materials. Our dedicated service organization consists of skilled service engineers and we offer quick response to assist a customer if required.

CD-0.25

product opties

The CD unit is a dissolved air flotation and flocculation unit that treats bilge water to below 5 ppm. The technology enables treatment of bilge water of various composition as the operator can adjust the dosage to the current conditions at hand. It was developed onboard ships not simply to fulfil the MARPOL requirements but to meet onboard conditions.

 

Key benefits

  • Flocculation technology: no cartridge filters nor centrifuges required
  • Adjustable to the ship’s specific bilge water composition
  • 5 ppm type approved
  • Low energy consumption for low carbon footprints
  • Can be integrated with the Whitebox®
  • Low operational cost

The treatment process

The process can be divided in five stages: Oil separation, Aeration, Flocculation, Flotation and Filtration.

  1. Oil separation. Free oil floats on water and is separated in the oil descaler by gravity to the sludge tank.
  2. Aeration. Air is dissolved in the water under pressure.
  3. Flocculation. Flocculation chemicals are added and coagulate emulsions, chemicals, and particles to flocs.
  4. Flotation. The dissolved waste from the aeration process is released into the flocs that are lifted to the top of the flotation tank and removed to the sludge tank.
  5. Filtration. The clean water from the flocculation process is filtered to 0-5 ppm before being discharged overboard.

Max capacity 0.25m³ per hour.

The Marinfloc Whitebox® is a failsafe overboard discharge monitoring and control unit. It is installed between the Oily Water Separator (OWS) and the overboard valve. It prevents non-compliant discharge of bilge water and helps to protect the crew from accusations as it presents the evidence of the vessels activities regarding discharge. Apart from logging it also helps prevent illegal discharge from occurring.
All vital discharge data is recorded and linked to the vessel’s GPS; the Whitebox® houses all necessary monitoring and control equipment for the overboard discharge. A digital recorder stores all critical data such as oil content, valve settings, flow via the oil content monitor and overboard flow, door open/closed, vessel position, and time.

 

The Whitebox can also monitor sewage overboard pump or STP running if connected.The data is stored in a secure digital format in the recorder and the history can be presented on the display or on a separate computer. That enables the crew to present the discharge data to USCG, Vetting, Class or port state and can prove that the operations have been compliant. The data is so detailed that extensive analysis can be made for preventive and performance reports.

 

The OCEAN GUARDIAN® can be connected to the Whitebox that can close the three way valve in the Whitebox when the vessel passes the 12 nautical mile line anywhere in the world. The Whitebox can also be used to monitor the discharge from the clean drains such as drains from the AC system or air cooler drains from the main engine. This type of water is generally very clean and could be pumped directly overboard which is approved by most classification societies. However as it may contain oil we recommend to discharge it through the Whitebox and if oil is present it will be directed to the bilge water tank for treatment by the OWS. This will greatly reduce the daily bilge water yield and the operation time and running costs of the OWS.
