Hydrolysis Acidification

This study aimed at the application conditions of environmental materials in sweet potato starch wastewater by hydrolysis acidification process. The removal rates of COD and soluble protein were investigated to find suitable natural setting time, the quantity of acidic steeping liquor and pH. The results showed that traditional fermentation not only consumes time but also scarcely removal efficiency in short time. 40% acidic steeping liquor was added as an optimum dosage for effective treatment. In addition, the effort of pH (3.0-9.0) on the hydrolysis acidification of wastewater was investigated. The removal rates of COD and soluble protein reached 26.9% and 76.3% respectively at pH4.0. Therefore, pH was adjusted to isoelectric point that can effectively reduce the burden of subsequent wastewater treatment.

Pre Treatment

This study aimed at, pre-treatment of sweet potato starch wastewater and acquisition the application conditions of environmental materials though coagulation precipitation. The removal rates of COD and turbidity were investigated by process to find kind and quantity of suitable coagulant, quantity of coagulate aids, pH and setting time. The results showed that poly aluminum ferric chloride (PAFC) was chosen as an optimum coagulant for effective treatment. The optimal coagulation precipitation conditions were determined as follows: pH8, dosage of PAFC 1200mg/l, PAM100mg/l, sedimentation time 30 min. At optimum conditions of coagulation precipitation stages, the removal rate of COD and turbidity reached 25.8% and 67.5%, respectively. Therefore, coagulation process reduced the burden of subsequent wastewater treating.

Anaerobic Sludge Blanket

A pilot-scale upflow anaerobic sludge blanket (UASB) reactor was used to study the sweet potato starch wastewater treatment performance and its influencing factors. Under normal temperature conditions, the operating parameters of sweet potato starch wastewater from UASB treatment was optimized, and the better conditions from different influent CODcr concentrations was obtained. The impacts from trace elements MgCl2, FeCl2, CoCl2, NiCl2 on physiological and biochemical characteristics of anaerobic granular sludge was developed.

White sweet potato starch (Ipomea batatas L.) and avocado seed starch (Parsea americana Mill) derived from local plants have the potential to be developed as agricultural products. Starch is a hydrocolloid compound as a potential local resource to be utilized. Glycerol function as an anti-freezing which is hygroscopic. This study aims to determine the ratio of white sweet potato starch with avocado seed starch and the concentration of glycerol for making edible film. This study was an experiment using a completely randimized factorial design with 2 (two) main factor consisting of a comparison of white sweet potato starch and avocado seed with 3 levels: P1 = 35%:65%., P2=50%:50%., P3=65%:35% and glycerol concentration with 3 levels: G1=1%., G2=2%., G3=3%. The best result reasearch were content of 23.03% (tratment P1G1), solubility of 55.57% (treatment P3G2)., swelling test of 9.83% (treatment P2g3)., elongation of 8.18% (treatment P3G2)
