ABSTRACT Water is a very important substance for human life, so more water is needed. Peat water is surface water resulting from the accumulation of plant material residues in a large volume with a pH ranging from 3-5, in general this makes peat water not meet the requirements for clean water quality, but in water shortages it forces peat water to be processed into clean water. Peat water …
viii ABSTRACT Magnetic susceptibility and composition of magnetic particles from natural sand iron oxide, at Rokan River in Riau Province were characterized as a function of the rotating speed of ball milling tubes. Samples were separated into the magnetic particles from non-magnetic particles using Iron Sand Separator.
Water pollution is a major problem that requires proper treatment. 4-nitrophenol (4 NP) is an organic water pollutant which is very dangerous for living things because it has mutagenic, phytotoxic and cytotoxic effects.
