ACO Water Maker WM3

The ACO Marine WM3 is a water treatment unit with extremely low energy consumption designed for recycling wastewater from wastewater treatment plants as potable water. With a physical size comparable to that of a small domestic refrigerator it produces Drinking Water and technological Pure Water in a range of capacities. This device is equipped with the RCS System and all other special features supplied as the standard in this class for ensuring perfect purity and sterility of water.

 

ACO WM3 – THASMS (hybrid technology of asymmetric selective membrane separation) can treat any type of input water and effectively removes all forms of biological, bacteriological, mineral, gas or toxic contamination. The treatment process converts treated effluent water by purification into the equivalent of pure, clear springwater. This is achieved purely by the physical processes of the system with no requirement for any chemicals.

ACO WM3 offers unrivalled benefits

  • High-efficiency water purifying technology
  • Suitable as a grey water treatment solution, subject to specification
  • Produces water for any use: demineralised (sensitive technical/sanitary applications) or potable drinking water
  • Highly affordable compared to traditional solutions. Reduced liklihood of membrane blockage means less pressure to pump the water through the system
  • Electronic monitoring & control
  • Small units, they can be modified to fit any system
  • Works with all standard marine power source including solar
  • Environmental benefits of reduced water pollution and sustainable water use
  • Reduces load on vessel’s main fresh water generation by utilisising additonal sources from pre-treated wastewater

The ACO Marine WM3 purifier range is suitable for use on board all vessel types and can effectively recycle wastewater treated effluent into drinking water, or high quality technical water for such applications as general surface cleaning, laundry, showering, toilet flushing, engine cooling – indeed any fresh water requirement.

Amazing Purity

Regardless of the source of the water to be treated, 100% sterility of the treated water is guaranteed and closely monitored by the control system. The water is sterilised more than ten times by a combination of several technologies, including non-chemical sterilisation by ozone, all of which combine to destroy any bacteriological and biological contamination. A special function of the WM3 unit even removes dead bacteria. The entire process is based on physical, natural processes controlled by the integral computer and our in-house software. The resultant water contains no bacteria (living or dead), undesirable metals and toxins nor any biological, gaseous or other forms of pollutan.

The ACO WM3 can take this one step further and add vital minerals to produce perfect, mineral balanced, drinking water of unbeatable quality.

The ACO WM3 sterilisation procees is so effective all types of produced water can be stored in vessel holding tanks for at least 120 days without any further treatment.

Typical forms of pollutant encountered in marine wastewater

  • Pathogens: (giardia lamblia, salmonella, shigella, typhoid, yersinin enterocolitica, viral hepatitis & others)
  • Non-metallic contaminants: (phosphates, nitrogen and others)
  • Metallic contaminants: (aluminum, arsenic, barium, cadmium, copper, chromium, iron, lead, lithium, manganese, mercury, molybdenum, nickel, silver, uranium, and zinc)
  • Non-metallic contaminants: (acids, ammonia, nitrate, phosphates, boron, chloride, cyanide, fluoride, radium, selenium, sulfates and various radioactive isotopes)
  • Synthetic organic contaminants: (pharmaceutical drugs, chlorinated solvents, hydrocarbons and polychlorinated bi-phenols (PCBs) and others)
