Novel Environmentally Benign Technique for the Removal of Fluoride, Arsenic and Coliform from Wastewater
Keywords:
Fluoride, Arsenic, Coliform bacteria, Homemade bio-sand filter.Abstract
An environmentally benign homemade bio-sand filter is used for the removal of fluoride, arsenic and coliform from drinking water. This method is facile at rural area and has low cast. The physiochemical analysis of water samples had been done before and after the treatment time with filter using standard methods. Optimum operating time was determined for maximum removal of these impurities by running experiment for 2,4,6,8 and 10 hours respectively. The maximum reduction of fluoride, arsenic and coliform bacteria in percentage was 81.4, 91.1 and 100.
