Abstract
In a process for clarification of liquids, especially raw juice by continuous crosscurrent filtration, which for improvement of the filtration output is run with a high solid portion in the retentate circulating circuit, during the starting phase an additional retentate discharge from the retentate circulating circuit takes place, which is relatively small in comparison with the retentate discharge taking place during the stationary operating phase. By this measure, a further improvement of the filtration output is achieved.
