摘要
FIELD: chemical industry and agriculture. SUBSTANCE: clinoptilolite is treated with a sewage water in a module consisting of two columns connected to each other in sequence. The sea water is passed through the first column at a temperature of T1 until the equilibrium on potassium is attained with the source water. Potassium concentrate is obtained by regeneration of the first column with the sea water heated to a temperature of T2. A finished product is obtained by passing the concentrate, cooled to the temperature of T1, through the second column until the equilibrium with the concentrate is attained. The processing temperature is chosen in correspondence with the consideration 50 C 50°CT2-T170°C 170 C. The relationship of clinoptilolite volumes in the first and second columns is chosen to be (2-3): 1. EFFECT: improved quality of finished product. 2 tbl, 2 dwg
