26 for illustrative purposes only a single representative module 28 is shown in fig1 2 and 3 of course the number of module in a given installation will vary based upon a consideration of many factors as known by persons of skill in the art it is important to note however that the design of the clarifier support structure is especially suited to maximize the flow of liquid through the modules 28 as shown in fig1 the module 28 that is adjacent to the longitudinal truss 24 one truss 24 is shown in fig1 snug right up to the truss 24 thereby preventing liquid from flowing upwardly between the module 28 and the longitudinal truss 24 similarly the module 28 which is adjacent to the lateral truss 22 snug right up to the truss 22 thereby preventing liquid from leaking i e flowing upwardly between the module 28 and the trusses 22 and 24 a baffle 30 is supported on the main major transverse truss 22 it serves to direct the flow of liquid entering the front of the tank 12 downwardly in order to maximize the flow of liquid into the lower rear portion of the tank 12 thereby maximizing the flow of liquid upwardly through the modules 28 in the upper rear section of the tank 12 in indicated by arrows in fig3 turning now to the details of the structure which supports the module support members 26.
