    In a steadily operating vertical secondary clarifier, there exist a sludge-water interface and a compressive interface and four zones of different settling characteristics :.a clarified zone, a flocculent settling zone, a transition zone and a compressive zone. For a given sludge, the position of sludge-water interface depands on the upflow velocity , and the position of the compressive interface depands on the concentration and the velocity of under - flow . Generally, the sludge - water interface which contributes to clarifying ability is primarily influenced by the surface area of the tank , and the height of water surface above the inlet is the secondary factor . As to the compressive interface which contributes to compressive ability , the depth below the inlet is the primary and the surface area is the secondary factor.
