Abstract

In this paper. the equation of multi-staged countercurrent washing process was derived under the condition of different wash ratio. and practical process was simulated by romputer according to the cquation. At the same time. the suspension of caleuim sulphate and citric acid in citric acid proluction was taken as research object and the test of cake filtration and wash was condueted. The resul showed that the value obtained from tests basicallyaccorded with the data calculated.

Keywords：cake fltration: wash: citric acid: computer simulation
