The solids will settle and fall through the slot and begin to digest in the bottom.

An Imhoff tank is a structure designed to provide primary wastewater treatment. This process is known as chaining. First the sewage enters the upper sedimentation tank whose bottom has sharp inclinations.

The Imhoff tank is a primary treatment technol-ogy for raw wastewater designed for solid-liquid separation and digestion of the settled sludge. 1362 Sludge Withdrawal It is desirable to keep as much di gested sludge as possible in the tanks to promote digestion of the fresh sludge. Sedimentation volume 581 litres and digestion volume 1388 litres suitable for 19 people with equivalent pro-capita water supply of 150 litres per inhabitant per day.

Occasionally the slot will plug and the recommended course of action is to drag a chain along the slot. The first chamber should be at least half of the total length in case of more than two chambers and a length of 23 of the total length should be considered when there is only two chambers exist.

Other Imhoff tank or sludge digester may speed the development of these conditions particularly where the raw solids loading is near the design value. It is provided that 092m2area and 03meters depth is needed for sedimentation when the sewage inflow rate is 10litres per minute. Design of absorption system.
