专利汇可以提供Separating method using membrane专利检索,专利查询,专利分析的服务。并且PURPOSE: To treat waste lig. with inexpensive equipment, by treating raw lig. contg. proteins, amino acid, succharides, e.g., waste lig. from food manufacture, with filter medium made of copper with lattile defects, the with semipermeable membrane so as to prevent propagation of microorganism.
CONSTITUTION: While waste soln. from which starch of potato or corn has been recovered, or soybean waste soln. in manufacture of "miso" (Japanese seasoning) or "tofu" (bean curd) passing through a filter medium made of copper with a number of lattice defects, e.g., woven or unwoven cloth, or net, each made of copper fiber, the microorganism contained in the waste soln. is made extinct, then it is treated with a semipermeable membrane. Hereby, decline in water penetration through the semipermeable membrane due to adherence of microorganism to the membrane, lowering of performance of the semipermeable membrane due to attack by microorganism, and lowering in MW of proteins due to microbiological degradation can be restrined effectively.
