Scanship AS products

The international focus on discharging wastewater in coastal waters is increasing. New standards for discharge and various regulations are driving the maritime industries to process all wastewater onboard. To meet new demands and future requirements, Scanship offers a complete system for wastewater treatment, the Scanship AWP (advanced wastewater purification).

Scanship incinerators are designed in a multi-chamber configuration, semi-pyrolytic, having low flue gas emissions within IMO MARPOL regulations. The incinerators are also capable of meeting EU regulations, which is in accordance with the future general demands for air emissions. The automatic feeding technology is developed to secure a homogenous combustion and low dust emission. The solution is also optimal for burning sludge from foodwaste and wastewater. It can be equipped with a fully integrated Sludge Oil Burning System.

Onboard a modern cruise ship a substantial amount of foodwaste is collected from galleys, pantries and preparation. To align with future requirements, the cruise industry chooses to process foodwaste onboard. Scanship has developed an efficient vacuum system for collecting, transporting and further processing of foodwaste. Transportation by vacuum reduces the need for complicated pipelines and pumps. It is hygienic with minimal odour and does not have any infectious water in circulation between feeding stations and the processing equipment. Vacuum transport ensures safe transport through the pipes to the central processing system. Vacuum transportation also contributes to the homogenizing of the food waste before further processing. The Scanship Foodwaste System meets requirements of the U.S. Public Health and U.S. Coast Guard regulations as well as the European HACCP standards.

Clean water is a precious and valuable resource, and turning yesterday’s waste water into tomorrow’s asset is Scanship’s forte. Scanship’s success in providing and servicing water treatment systems that meet or exceed the most rigid standards and regulations for the cruise line industry, in the most sensitive environments, are deeply rooted in broad expertise and experience treating wastewater.

The Scanship scrubber water treatment system is designed to purify wash water from marine scrubbers in hybrid and closed loop operating modes. The system will operate in accordance with MEPC.258(68) (2015) and US EPA VGP sec 2.2.26 (2013). The wash water treatment system collects inlet water from the scrubber wash water collection tank. The purification process is based on chemical precipitation where dissolved solids and suspended particulates are aggregated into particulates through a coagulation process assisted by a flocculant and coagulant. The particulates are thereafter separated in a dissolved air flotation process. As a secondary process, the water is filtrated by a rotating non-pressurized drum filter specially designed to remove the finest particles, if any.

The availability of a plentiful, safe, clean water supply for use aboard ships has long been taken for granted. It could be bunkered in port or produced with waste heat, cheap fuel, and air conditioning condensation aboard the ship. That situation is rapidly changing. Growing populations, more and bigger ships, changing environmental and natural resource conditions, rising fuel prices, environmental footprint concerns, and greater awareness of water borne pathogens are all putting pressure on ship and port water supplies, world-wide.
