New Water Maker

Posted by Irina Tabakina

ACO Marine launched a new water recovery system that is designed to give vessel owners greater capacity to reuse the treated effluent from wastewater treatment plants.

The ACO Water Maker WM3 converts treated wastewater into pure distilled technical water for such applications as general surface cleaning, laundry, showering, toilet flushing, engine cooling, etc. According to ACO Marine, the unit has extremely low energy consumption and reduces a ship’s need to take on fresh water in port or to make its own water through reverse osmosis or flash evaporation – both high energy consumers.
It is suitable for use onboard all vessel types and can be easily retrofitted to ACO Marine’s Maripur and Clarimar wastewater treatment solutions in addition to third party systems, the manufacturer said. A typical unit has a footprint not dissimilar to the size of a small domestic refrigerator, with water-making capacities ranging from 6,000 to 24,000 liters per day.
The water maker reduces the kilowatt power per liter of water produced compared with conventional methods and can cut wastewater dumping significantly. The unit also fulfils the function for vessels requiring freshwater generation redundancy. The ACO WM3 uses a hybrid technology of asymmetric selective membrane separation (THASMS) to treat any type of input water and remove all forms of biological, bacteriological, mineral, gas or toxic contamination. The unit can also take this one step further and add vital minerals to produce mineral balanced drinking water.
