    multiple removable filter elements (“filtration tentacles”)
    attached to a cartridge head plate. Each filtration
    tentacle consists of a central perforated tube surrounded
    by a specialised membrane. A removable oil-resistant
    polymeric gasket provides a watertight seal between the
    cartridge and the deck. A JellyFish® membrane filtration      Tentacles

    cartridge is depicted in Figure 2.


    The cartridge length is 1,372 mm. The dry weight of
    a new cartridge is less than 9 kg, and the wet weight
    of a used cartridge is less than 23 kg. No heavy lifting
    equipment is required during exchange.


    The filtration tentacle membranes provide a large surface
    area, resulting in high flow and suspended sediment           These values translate to a conservative design
    removal capacities. A typical JellyFish® cartridge with       membrane filtration flux rate (flow per unit surface area)
