| Popis: | Suspended solids problem in water is an issue as old as water treatment itself. Suspended solids can be causativeto eroding through abrasion of impellers, pump casings, pipes and other water works related appurtenances.It is therefore appropriate that suspended solids must be removed as early as possible in the water workstreatment facilities. It is usually done at the river/lake intakes to reduce the coarse particulate matter thatwould otherwise adversely affect the water works thereafter. The fine particles that will escape the entrapmentat the intake works would therefore require further and more effective system that would remove this fraction.By and large this removal process is achieved by chemically aided process such as coagulation/flocculationunit operation. This process is expensive and demands high level trained personnel to man them. In the samevein then a simple and effective system is proposed. This is a swirl or grit removal system that does not needany chemicals, moving parts or even highly trained personnel to operate them. This paper is looking at thetheory of the “Tea Cup Effect” and how it has been used in practice to remove or reduce suspended solids fromwater. The paper gives some examples where such devices have been used and how effective they have been. |
