Our SDB polymers could be used in clarification of sugarcane process. After the extraction of the cane juice, mixed juice from the extraction mills need to be purified by adding heat, lime and a flocculants. The lime will be used as a suspension of calcium hydroxide in a sucrose solution, which will form a calcium saccharate compound. The enzymes in the juice will be removed by heat and lime and the PH will be increased from a natural acid level of 5 - 6.5 to a neutral level. When heating over 100°C, the neutralized juice is treated with other types of flocculants and pumped to a clarification vessel where the mud settles and the clarified liquor overflows which could be used to the evaporation stage for further processing of juice clarification.

PAM application for sugar cane refining in three main aspects:

• Sugarcane juice clarification: about 105℃, bagasse precipitation - filter cake,14-20 Brix
• Syrup concentration: 85-90℃, so that the syrup is concentrated to 65Brix
• Sewage treatment: squeezer / generator cooling water, equipment cleaning / floor cleaning / boiler dust removal wastewater, evaporation / crystallization condensate, etc

SDB team will help our customers to choose the right flocculants for the sugar refining process.
