Studies regarding water clarification by fast ascending and descending filter in multiple homogeneous layers [articol]

Abstract

In this paper are studied the processes of rinsing water by using fast ascending and descending filter equipped with multiple homogeneous layers. In the rapid filtration descending to show the structure and characteristics of the types of materials, quantitative and qualitative changes occurring in the process of rinsing whit evidence of the parameters determined. Instead the fast ascending filtration with multiple homogeneous layers is a similar process to that of the rinsing water by decanting suspension static or dynamic type. The comparative experimental researches of ascending and descending filtration under the same filter structures, turbidity and speed filter,put in evidence the performance and cycle times of water filter.
