Abstract
chitosan may be used to reduce the bacterial load of water. Material prepared according to the method of Radhakrishnan & Prahu (Res. Ind., 16(4): 265(1971)) used in 1% solution in 1% acetic acid was added at 10 ppm level to contaminated water and allowed to stand for 45 min. Cultures of E. coli, Staphylococci and a mixture of the 2 were inoculated into ordinary and muddy water. Bacterial load was determined, and it is shown that chitosan has excellent qualities as a coagulant/water clarifying agent, especially for muddy waters or those contaminated with suspended matter or bacteria.
