    PENGOLAHAN AIR GAMBUT DENGAN MEDIA FILTER BATU APUNG
    (2013-01-07) Edwardo, Anderson; Darmayanti Lita; Rinaldi
    Peat water is surface water sources are often found in the province of Riau, dark brown to black (124-850 PtCo), high value of organic (138-1560 mg / l KMnO4), and acidic (pH 3.7 to 5.3 ). Conditions of this water showed that the peat water still requires special processing before it can be used as a source of drinking water. One alternative treatment to reduce color of the peat water is the pumice filter. The purpose of this experiment was to study the use of a pumice stone in peat water processing. The principle of this peat water treatment was the process of acclimatization for 6 days in advance to grow biofilms in layer of pumice filters that have been filled with pumice stone and gravel. Once it was done running for 7 samples. In the pumice filter occured adsorption process, filtration process and biological activity by micro-organisms. This experiment used pumice filter reactor, with three variations of the filtration rate was 0.25;1,5;5.0 m/h and thick pumice stone was 60 cm. The best results were obtained in this experiment was the filtration rate 0.25 m / h and 60 cm thick pumice, where optimal efficiency in reducing peat water colors at 94.15%, reduced organic content at 89.78%, increased pH value at 64.58%, and reduced value of turbidity at 98.51%. This result suitable with water standards of PERMENKES No.416 / MENKES /PER/IX/1990, except for the organic content parameters.
