Options and Accessories Available  (order separately) 

AMI's SY Series Seawater RO Systems are available with a wide variety of optional add-on equipment.  All assemblies include hardware and mounting equipment for easy upgrade to your new or existing system installation.

Wall Mount Filter Cartridges

Includes mounting bracket and Isolation Valves to close the line when changing the filter cartridge. 

Pretreatment Options Available:
  • Oil/Water Separators protects the membranes from oily or polluted water sources.
  • Plankton Filters trap suspended solids larger than 100 micron, thus providing additional protection for the system’s prefilters, which extend the prefilter element life.
  • Commercial prefilters provide longer intervals between necessary filter cleaning and replacement.
Post-treatment Options Available:
  • pH Neutralizing Filters raise the pH of the RO fresh water. Filters are self-limiting to correct pH only excessive enough to reach a non-aggressive equilibrium.

Prefilter Assembly for Reverse Osmosis RO System

Media Filters

AMI Media filters feature fully automatic backwash for easy, trouble free maintenance. 

  • Multi-Media Filter for sediment filtration to approximately 10 microns.
