PULP-PRESS WATER PURIFICATION METHOD

摘要

FIELD: food industry. ^ SUBSTANCE: method envisages mechanical purification of pulp-press water. One adds to water aluminium sulphate for pH to be 4.2-4.5. Water is mixed with ammonium condensates and alkalised with lime water with subsequent sedimentation of impurities in the sedimentation reservoir. Clarified water is heated and delivered for diffusion. After aluminium sulphate addition and a 4.2-4.5 pH value attainment pulp-press water is treated in a 0.23-0.30 T pulse magnetic field during 5-6 sec. ^ EFFECT: pulp-press water purification effect enhancement. ^ 1 tbl, 2 ex
