Fluidizing teeter water is introduced over the entire cross-sectional area at the base of the teeter chamber through evenly spaced water distribution pip As the feed enters the main separation zone it expands into a teetered or fluidized bed as a result of the rising current of water...

wastewater lift design because if the wastewater velocity is below 3 ft/sec there will not be enough energy to scour the pipe of solids Conversely water flowing above 9 ft/sec can scour the pipe material and damage the force main The final constraint is that the Hazen-Williams Equation should not be used on force mains larger than...
