"Estudo do carvão do coco babaçu como material poroso para filtros".

Abstract

The work presented in this dissertation concerns a study of babaçu coconut coarse as a porous material for filter, using double bed made up of a coarse layer upon a sand one. The sdudy have presented the characterization of the ma teria! according to the A.W.W.A standard, as wel 1 as the results of filtration tests performed in a water trea^ tment plant at Alto Branco, Campina Grande - Paraíba. In the stage of tests the performance of layer compound by Sand-babaçu is balanced with a sand-antrac i t e , which is used in water treatment plant. The basic para meters chosen to analyse the performance of the materi al were' the head of lose in several leveis in the filter and the turbidity removal of the treated w a t e r . The turbidity includes several other factors, that affects the filtration. The same consideration is true for head loss which makes it possible to find out the retention capacity of flocs by filtering media. The babaçu coconut coarse have presented a' good performance, and can be considered as a new option for the water treatment plant, mainly in north and northeast of Brasil, where babaçu exists in great quantity.
