  • Page 4 Scope of delivery Seawater R.O. AQUATEC :  High-pressure pump with electric motor, pump head in Duplex-stainless steel 1.4462.  Feed pump 230 volt.  GFK membrane housing and membrane-element.  1Filter housing included charcoal filter-cartridge for fresh water flushing.
  • Page 5 Introduction The principle of reverse osmosis (RO) In natural sciences and technology, osmosis is perceived as the directed migration of molecules through a semi permeable membrane. The chemical and physical structure of the membrane determines which molecules are able to pass and which are not. For this reason, it is called semi-permeable, which means as much as halfway or partial permeability.
  • Page 6 Note: If Aquatec is run in brackish water or in low-salt water, the fresh water production must not exceed the displayed value! In this case, regulate the pressure under continuous observation of the produced amount of water until the normal level of fresh water production is reached.

    Long term preservation (mothballing) of the plant 1 Description: Prior to a longer period of shutdown, the Aquatec has to be preserved with chemical no. 3 (Biocide). After mothballing, the plant can be shut down for 6 months, depending on the environmental conditions.
  • Page 12 Long term preservation (mothballing) of the plant 2 A standard 1/2” hose can be used for this purpose, which should be fitted onto the HP threaded connector of the high pressure pump to drain the water out into a bucket. Then drain the all the water from the pump, which is important if there is a risk of frost, if possible it is also preferable to blow pressurized air through it in the direction of flow, for this purpose remove both hoses.
  • Page 13 9) If there is no change in freshwater output, repeat the procedure 1 to 7 with chemical no. 2 (Acid). Attention: Prior to a longer period of shutdown, the Aquatec has to be preserved with Biocide after cleaning and flushing. Caution: At every recommissioning after cleaning or mothballing, divert the product water over the test-outlet for the first 30 minutes to rinse the chemical completely out of the system.

During assembly of the hose nozzles and fittings, few windings of Teflon-tape have to be wrapped around the screw thread against screw direction as tightly as possible.
  • Page 19 Installation guide page 2 Filter housing For a good sealing of the filter housing, please lubricate the O-rings in the filter bowls with the included acid-free silicone grease. Mount the filter housing at an easily accessible place. Connect the filter inlet with the outlet of the feed pump and the filter outlet via PVC hose with the high-pressure pump.
  • Page 20 Installation guide page 3 Fresh water flushing system Mount the filter housing for the charcoal filter at an easily accessible place between the fresh water pressure system and the pre-filter housing. Install the hose connections corresponding to the flow diagram. Attention: The maximum pressure in the inlet (seawater, fresh water flushing) must not exceed 2.5 bar.
  • Page 21 Installation guide page 4 High-pressure hose, to be cut into two parts according to your needs. To allow a flexible assembly, the high-pressure hose is provided as one piece of 4 meters (13.1 feet) with a V4A high-pressure fitting at both ends. Please fit the required lengths accurately before cutting the hose.
  • Page 22 Installation guide page 5 Attention: Secure the high-pressure connection fittings in the plastic end caps of the pressure pipe against twisting with a 19 mm open-ended wrench (not necessary on end caps fittings secured with metal strips) and tighten the union nut of the high-pressure hose with a 17 mm open-ended wrench with approx.
  • Page 23 Installation guide page 6 Tank for membrane conservation and cleaning The tank has to be mounted above the system to ensure the flow to the plant. If this is not possible, an additional feed pump has to be installed. The tank can be fastened to any plane surface with the help of the enclosed webbing and the plastic long eyelets.

  • Page 39 Dimensions Glossary Coarse filter (strainer) is mounted behind the thru-hull fitting beneath waterline and protects the feed pump from gross contamination. Feed pump provides for a good inlet to the high-pressure pump and extends by the inlet pressure the lifetime of the sediment filters. Sediment filters are mounted in front of the high-pressure pump and prevent the entry of smallest particles in the high-pressure pump and membranes.
