Abstract
PURPOSE: The ultrafilter which can generate the specified filtering pressure by the reduced consumption of electric power and the power cost, by introducing the inert gas, etc., into the balance tank in the circuit for filtering the stock solution so as to raise the internal pressure of the balance tank.
CONSTITUTION: The stock solution is introduced into the balance tank 1 through the stock solution feed port 2 and the prefilter 2'; the stock solution being supplied from the balance tank 1 is recycled by the stock solution pump 3 and is returned to the balance tank 1; under this condition, the stock solution is passed through the ultrafilter 4. The compressed inert gas or air is introduced into the balance tank 1, through the feed port 5 for raising the internal pressure of the balance tank 1 on purpose to make possible the required filtering pressure to be covered by this internal pressure. According to this mechanism, the pump of small size and low output can satisfy the requirement, so that the electric power consumption and the power cost can be reduced.
