Description

The D-D 125 Gallon RO Unit, is a 3 stage, 125 gallon a day reverse osmosis unit with all connections for installation.

Reverse osmosis water is essentially free from chlorine, nitrates, phosphates and heavy metals and is an ideal base for making up salt solutions.

Tap water is generally full of pollutants and the effect on your aquarium can be quite severe depending on how bad the water is in your particular area, fueling algae and diatom blooms which must be then maintained by chemical methods.

D-D have a comprehensive range of RO units to suit every application and depth of pocket but offer 3 main units with either 50, 75 or 125 G membranes.

The three stages consist of :

1 – A 10″ 5 micron pre-filter to remove sediments and particles from the mains water to protect the membrane from clogging and extend it’s life. This is housed in a clear membrane to allow you to monitor the colour and life of the disposable element. We recommend that this low cost filter element is changed at a maximum interval of 6 months.

2 – A 10″ 10 micron block carbon filter. This carbon filter is designed to remove the chlorine from the water. In the UK the chlorine levels are generally not high however we still recommend that you change this element every 6 months.

3 – The RO Membrane and housing. This stage holds the membrane itself. All D-D membranes are high quality thin film membranes the membrane is semipermeable: it allows water molecules pass through while acting as a barrier to dissolved solids (i.e.: mineral chemical contaminants). In general a membrane will last about 2 years (depending on water quality in your area), especially if regularly flushed. The best way to test the membrane is using a TDS meter to determine if the quality of the water has deteriorated.

All D-D RO Units come complete with the following:

  • Flow restrictor with integral membrane flushing valve.
  • Self-piercing tap connector.
  • 2m of 1/4″ RO tubing in white, blue and orange.
  • Saddle valve for the waste pipe return.
  • Filter Spanner.
  • Full instructions.

Optional Extras include:

  • DI Resin Pod – Provides an extra final stage of filtration to remove the last 2% of contaminants that the RO Unit leaves behind.
  • Garden Tap connector – Allows the unit to be connected to an outside garden tap fitting and some washing machine taps, rather than directly plumbed into pipes

Please Note:

When choosing the size of RO unit remember that the output flow will vary greatly with temperature and mains pressure. The 75 gallons quoted on the membrane refers to US gallons at a standard pressure and temperature of 25C. In practice the supply water is never this warm and therefore the flow rate is reduced.

If as a rule of thumb, on any manufacturers RO units, if you expect to get half of this tested output in practice then you will not be disappointed.
