    Solution:

    The transmission of light is reduced by the use of oil spill.
    Filtration of water can be done extensively by the use of ceramic candles.
    In a suspension the suspended particles are sedimented by the use of alum.
    Water with impurities is disinfected so that it can be used for daily purposes and disinfection of water is done by bleaching powder.
    Typhoid is a disease which is caused by a microbe known as Salmonella typhi is a water borne disease which spreads faster through water contact.
