METHOD AND SYSTEM FOR RECYCLING FOOD PROCESSING RESIDUAL LIQUID AS RESOURCE

摘要

PPROBLEM TO BE SOLVED: To provide a method and a system for recycling a food processing residual liquid as a resource which are low in cost and suitable for commercialization. PSOLUTION: The method for recycling a food processing residual liquid as a resource has a pretreatment process for solid-liquid separating the food processing residual liquid into a solid fraction having a moisture content of 80% or less and a liquid fraction from which solids having a particle size of 1 m or more are removed, and a membrane concentration process for dewatering and concentrating the liquid fraction obtained in the pretreatment process to separate it into concentrated values and treated water. The system for recycling a food processing residual liquid as a resource has a pretreatment means for solid-liquid separating the food processing residual liquid into the solid fraction having a moisture content of 80% or less and the liquid fraction from which solids having a particle size of 1 m or more are removed, and a membrane concentration means for dewatering and concentrating the liquid fraction obtained by the pretreatment means to separate it into the concentrated values and the treated water.
