RO DI MARINE FISH AQUARIUM REPLACEMENT WATER FILTERS HRO-3-DJ RODI FILTER
Marine Fish Aquarium Replacement Water Filters - HRO3-DJ Reverse Osmosis Rodi Water Filter Packs
This jumbo [12"x2.5"] pre-filter can used for between +/- 4,000 litres to +/- 4,500 litres of RO DI water produced [assuming a 1:1 waste to pure ratio and average chlorine levels].
Membrane flow is rated in GPD [gallons per day] at 55psi so on average a membrane will produce at the following flow rates: 50GPD = 8 Litres Per Hour, 75GPD = 12LPH, 100GPD = 18LPH, 150GPD = 22LPH and 200GPD - 33LPH.
The Pentek 100GPD TLC membrane is a new generation membrane that has a higher rejection rate [98%] versus standard TFC membranes [96%] and the Pentek TLC membrane can deal with feed water TDS levels up to 4x what standard membranes can and you can download the Pentek TLC performance data sheet here.
Our resin is highest food grade mixed bed deionising resin and can also be supplied loose so you can refill your existing refillable in line filter, or in a filled refillable in line filter. The post RO DI filter with this listing is for the jumbo [12"x2.5"] size which holds almost twice as much DI resin as the standard 10"x2.0" one.
All water contact parts are manufactured from high quality food grade plastics or stainless steel
