PRO-5-DJ REVERSE OSMOSIS RODI | MARINE AQUARIUM RODI FISH FILTER
High Volume* | Low Waste* Portable + Wall Mountable Reverse Osmosis RODI Purifier Marine Aquarium
We supply these systems with a manual first flush valve (see image 13) so you can direct the first bit of water produced out the waste line then through the RO to which allows resin to last longer. This flush valve can also be set to increase your operating waste ratio which is required in some areas where the TDS of the local water is high.
* high volume pre-membrane filters and resin cartridge can handle higher volumes than the standard filters allowing less frequent filter changes i.e. with these systems standard pre-filters will need to be changed every +/- 7,500 litres produced and high volume pre-filters every +/- 25,000 litres produced.
*Two RO membranes configured in series to reduce average waste from approximately 60% to around 35%. In this standard setup, the waste stream from the first membrane is further purified by the second membrane, significantly improving overall recovery.
Note: At your request membranes can alternatively be configured in parallel to increase flow rate, though this will result in a higher waste ratio. A series configuration—where the permeate from the first membrane feeds into the inlet of the second—is particularly beneficial when dealing with high-TDS source water, such as groundwater or bore water commonly found in WA and other regional areas.

Note: Testing of flow rates, waste ratio's and TDS readings were done with water at 28 degrees Celsius, 80psi water pressure and feed water with a TDS reading of 105ppm.
SYSTEM INCLUDES:
- Powder coated, mild steel folded bracket
- 3x 10"x2.5" white opaque or clear tinted filter housings [vertical ones]
- 1x 10"x2.5" 0.5uM poly spun sediment filter
- 1x 10"x2.5" Matrikx CTO high volume carbon filter
- 1x 10"x2.5" jumbo post RO mixed DI resin filter [2.5x as much resin as in line post DI filters]
- 2x high quality reverse osmosis membranes connected in series [flow rate depends on selection in drop down menu]
- 3x meters of high pressure 1/4" | 6mm water filter tubing
- 1x opening + closing housing ring spanner
- 1x standard* sink mixer diverter connector
- 2x garden tap connectors for 1/2" + 3/4" taps
- 1x manual first flush valve
Supplied with a tap connector to fit 1/2" + 3/4" garden taps [measures 20mm + 25mm in diameter respectively] as well as a standard* sink mixer diverter valve
* Standard mixer taps refer to a mixer tap where you can unscrew the aerator on the end of the tap and will be left with either a 20mm female thread or a 23mm male thread. If you have the 20mm female thread you'll need to use the inside to outside thread converter [supplied with the diverter valve] to connect but if you have a 23mm male thread after removing the aerator you won't need to use the thread converter
Easy to carry around and great for topping up freshwater aquariums, caravanning, camping and home use + produces 190-685 litres per day depending on mains water pressure, feed water quality and system selected
The reverse osmosis process results in the purest possible water and results in the total dissolved solids (TDS) count dropping by between +/- 99.9% and 100% with a post membrane DI
This purification process is commonly considered to be the most effective method of purification available to the public and will consistently produce the lowest level of contaminant.
RO will reduce/remove all of contaminant in the feed water including chlorine, fluoride, volatile organic compounds, disinfection by-products and heavy metals
