Clarifier for water - having set of inlet weirs with array of inclined riser cells below them to encourage settling of solids

摘要

Settling tank is for purifying water and consists of a settling space with inlet and outlet branches. Below this is a collection sump for accumulated sludge. Part of the settling space is divided into a radial array of cells one above the other, each inclined to the vertical. These cells are formed from pipes radiating from a central well down which the water flows. To leave the settler, it then flows up the inclined pipes to a final weir. The inclination of the pipes to the horizontal is 30-60 deg.C. Used for clarifying and purifying water. The settling effect is enhanced by the increased surface area across which the water must flow.
