Here is a typical commercial denitrator design. Some comes with added feature like ORP adaptor and additional inlet for feeding.
Advantage 1. Top cover can be remove easily for maintenance. 2. Recirculation pump to prevent dead spot. 3. ORP facililty for auto flowrate controlling. Disadvantage 1. Cost. 2. Sometimes over-rated. 3. Poor instruction manual. |

You are talking about my NR1000. Yes, it is pretty expensive to replace the pump head and that is why I am into DIY!

Till date, I am quite confident to achieve 20 l/hr and trying to do a 30 l/hr. To get close to zero, you will need to have 1 complete turnover a day......this means 1000/24=approx 42 l/hr. You might need 2 units of 1m tall denitrator to do that. There is a commercial unit that is this height, NR5000 from aquamedic.
