| Abstract | A pilot scale prefilter was used to study the performance of horizontal flow prefilter using coconut fiber as filter medium. Three different lengths of 250 mm diameter PVC pipe 2.0 m, 3.0 m and 4.0 m were used as filtration unit. Coconut fiber was soaked, rinsed and used as a filter medium. The density of coconut fiber was 81.6 kg/cum after compaction.
Two experimental runs were conducted with a filtration rate of 1.25 cum/sqm-n and 1.0 cum/sqm-n. Turbidity, color and total coliforms were measured during the filter operation. The turbidity, color and total coliform removal efficiencies were about 67.3% - 89.6%, 41.2% - 53.2% and 86.3% - 92.5%, respectively. The filter runs were short due to exhaustion of coconut fiber.
Horizontal prefilter using coconut fiber can be used successfully as rouging filter it coconut fiber available in local market in low cost. |
