一项研究进行了设计,构造ting and evaluating of an effective biosand filter. Different types of charcoal mixture such as bamboo, coconut and wood and carbon mat as an important filter media was used for the modification of biosand filter. The filter had seven layers with gravel, sand, carbon mat and charcoal which were responsible for filtration process. The filtered water analysed in every 20 min interval. The raw ground water pH was 6.12 while it passes through bamboo, coconut and wood mixture filter, the filtered water showed higher pH value. The filter in which mixture of charcoal used as filter media showed better removal efficiency of turbidity compared to control filter without charcoal and mat. The value of turbidity in filtered water of charcoal mixture filter was below 2 NTU which is the permissible limit of drinking water according to World Health Organization but for control it was average 14 NTU. Initially the flow rate was higher and gradually decreases with time. The flow rate of the Biosand filtered water decreases significantly with increase in turbidity. The charcoal based filter showed better removal of iron (II) (95-98%) compared to control (73-76%). The charcoal based filter resulted tastier water by enriching of water with mineral like sodium and potassium.
