Mechanical Separation: Conventional Tanks vs Spherical
	One of the most technical "comments" we get is that a conventional tank separates solids and liquids better than a spherical tank. There are two parameters involved: One, the distance from inlet to outlet which is termed the "Sewage Travel" and two, the speed of the effluent movement from inlet to outlet termed the "Sewage Velocity." The greater the travel and slower the velocity will result in the best mechanical separation. As it turns out a conventional tank has a greater travel, but because is a narrower tank; it has a greater velocity. The spherical tank has less length and sewage travel, but is much wider resulting in a slower velocity. The bottom line is that all things considered there is no significant difference in mechanical separation by either tank design.
