Sand Filters - filtration units for suspended solids and turbidity removal
Sand filters clarify moderately turbid water by passing it through a bed of graded sand. Filtration level depends on sand grain size and filtration rate. Backwashing cleans the filter by reversing flow and lifting the sand bed. Air injection before backwashing can reduce water use during cleaning: removes suspended particles from water using a- PRODUCT
