Custom solutions are available upon request.    


Header lateral systems consist of a series of screens laterals to either a central header or hub, allow designers to provide uniform flow through treatment media (ion exchange, sand, catalysts) at a wide range of flow rates and for a variety of vessel sizes and shapes. 
A typical vessel would utilise a header lateral assembly at the top to distribute inflow evenly across the bed surface. A second assembly, located near the vessel bottom, could collect the treated flow and pass it either through the vessel sidewall or by attaching the laterals to a central manifold out the vessel bottom. For a counter-current flow, a similar distribution and collection system can be designed.
