Further was bent, refined and analysed. Best results were obtained palm juice withthe increase in phosphat acid the dose 80 mg/l and without floculan that is 91.37 oS; whereas forthe analysis of the content phosphat, turbidy, the colour and the content of the lime were 31,8 mg/l,14,8 mg/l, 2749 ICU, 483 mg/l that is in the increase in the dose of phosphate acid 80 mg/l andfloculan 2 mg/l.Keywords :Phosphat acid, floculan, palm juice sugar.
