A weir is a device used to measure wastewater flow. Weir overflow rate (or weir loading rate) is the amount of water leaving the settling tank per linear foot of … tsop vs modchipThe overflow rate is defined as: Overflow rate (v o) = Flow of water (Q (m 3 /s)) /(Surface area of settling basin (A(m 2)) In many countries this value is named as surface loading in m 3 /h per m 2. Overflow rate is often used for flow over an edge (for example a weir) in the unit m 3 /h per m. The unit of overflow … See more Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the … See more Although sedimentation might occur in tanks of other shapes, removal of accumulated solids is easiest with conveyor belts in rectangular tanks or with scrapers rotating … See more Potable water treatment Sedimentation in potable water treatment generally follows a step of chemical coagulation and flocculation, which allows grouping particles together into flocs of a bigger size.
