What does sewage restrictor mean in practice?
The capillary or valve throttles the concentrate to a value that ensures the required pressure and flow along the membrane surface.
When does it matter?
Sludge in the restrictor increases recovery and the risk of scaling, while an element that is too large directs an excessive amount of water to the sewage system.
Which solutions are related to it?
The concentrate stream is measured by volume, compared with the permeate and a restrictor selected according to the GPD and feed conditions.
