D-D Reverse Osmosis 75 US Gal

The D-D Reverse Osmosis 75 US Gal is an excellent choice for creating your own high purity aquarium water. The D-D three stage units come with A 10" 5 micron pre-filter to remove sediments and particles from the mains water which extends the life of the membrane. This pre filter is housed in a clear container so you can tell when the cartridge needs to be changed by discolouration. The second pre filter is a 10 micron block carbon filter. This carbon filter is designed to remove the chlorine from the water and is worth changing every 6 months. The final stage of the D-D Reverse Osmosis 75 US Gal is a film membrane which is rated for flow at 25C and 50 psi. In practice however the fluid output from the membrane will vary according to water pressure and temperature. At lower temperatures all RO units used will produce a decreased flow rate by approximately 30% at 15 centigrade and by 50% at 9 centigrade. This must be taken into account when choosing the model suitable for your particular needs. Increasing the incoming water pressure by fitting a D-D Booster Pump will normally increase the flow rate considerably as they operate at 8 bar pressure and are particularly useful in areas where the mains water pressure is low or where the optimum flow is required from the unit. In addition the D-D Reverse Osmosis 75 US Gal comes 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.
