What is RO Membrane?
RO membrane is the most essential of the RO filters. Only pure water can travel through this membrane, which is a thin, semi-permeable layer with minute pores. In the filtration of water, RO membrane is crucial.
What is a Sizing Flow Restrictor?
All reverse osmosis systems require sizing flow restrictors (also known as Flow Controls or Capillaries). The Flow Restrictor must be suitably sized for the capacity of the RO membrane.
Flow Restrictors maintain the proper ratio of reject (to drain) and permeate (product) flow by applying pressure to the reverse osmosis membrane element.
How is membrane size and sizing flow restrictor interconnected?
To keep the system running at peak efficiency, the Flow Restrictor is inserted at the reverse osmosis membrane at regular intervals.
The flow rate is shown on the flow restrictor by a number in millilitres per minute. The flow restrictor should be matched to the production rate of your reverse osmosis membrane. As a result of the sizing flow restrictors, RO membrane sizes vary.
The table below provides recommendations for choosing an inline flow restrictor for your RO membrane

50 gpd |
420 or 525 |
75 gpd |

100 gpd |
800 |
What are Insert Flow Restrictors?
The insert flow restrictor is a piece of plastic that fits inside the RO membrane housing's brine outlet or inside the tube at the membrane housing's connection.
-If the "Insert" is in the connector fitting, you'll need to remove the connector and examine inside it.
-If it's at the tube's end, you can see it by unplugging it from the connector.
These must be placed appropriately in order to function properly, and they are not as simple to use or update.
