The Filter Press Instrument Test With Sadiment Product Analysis That Obtained in 2% CaCO3 Concentration

Abstract

Water is the most abundant element on earth, covering 70% of its surface and amount to about - about 1.4 thousand million cubic kilometer. Water is also one of the natural resources vital to the lives of everyday life - the day or for other purposes such as agriculture and industry. Therefore the presence of water in the community needs to be nurtured and preserved for staight life. The needs clean water from time to time increased rapidly, resulting in meeting the needs of both water quality and in sufficient quantity in a variety of purposes are faced with huge problems that have not been able to fulfill the needs of clean water. Therefore, the required water treatment is one of purification. Efforts can be made with the addition of purification and filtration agent. In experiments testing the performance of filter press equipment with water and the addition of CaCO3. From the results of experiment I, gained the most optimum plate frame license plate frame is the one with the percent weight of sediment 0.77% and water content of the vaporing 0,32%. From the results of experiment II, the optimum deposition results obtained at 30 seconds of sampling with a percent weight of sediment 0,72% and water content of the vaporing 0,37%. From the results of experiment III, the precipitate obtained optimum results on stirring for 40 seconds with a percent weight of sediment 0,67% and water content of the vaporing 0,92%. Of the three trials can be concluded that the longer the retrieval time and stirring time, the more it will increase the percent weight sediment and water content is vaporing. This is because the functions of filter press equipment running well. Keywords: Water, Filtrate, Time Sampling, Time Stir, Weight Sediment, Water Content of the Vaporing
