Removal Cyanobacteria by Diatomite Filter from Raw Freshwater and Potential Use in Watering Domestic Animals

Abstract

Abstract:Growing harmful cyanobacteria in freshwater cause several poisoning episodes of livestock, wild and domestic animal. Conventional surface drinking water treatment utilizes coagulation; flocculation, sedimentation, filtration and disinfection are inadequate and require great financial means or application in watering domestic animals. The filtration of raw freshwater by diatomite is very simple without use of chemical products. Samples of locally diatomite were dried ant calcined and tested to verify their efficiency to removal cyanobacteria cells from raw freshwater. The results obtained shows that filtration by calcined diatomite improve high efficiency to removal cyanobacteria and decrease the level of microcystin in the filtrate solutions.
