きる。When applying pressure between the fixed end plate and the movable end plate by tightening the nut of the filter plate group, it was necessary to measure the dimensions between the fixed and movable plates and tighten them (Y) in order to compress the gasket appropriately. By providing the protrusion l as in this embodiment and making the thickness of the gasket frame 3 a required amount l thicker than the protrusion 12, the protrusion abuts against the door plate and the nut cannot be tightened once more. The filter plate group, the partition plate, and the relay plate can be easily compressed to the optimum state by simply tightening the nut once until no longer possible.

They are organized into multiple groups (3 groups in this construction) heading downstream, and similarly supply the stock solution from the liquid supply port J on the fixed end plate, and finally collect the concentrated liquid from the drain loco/ provided on the same fixed end plate. While draining
The filtration efficiency is improved by passing the concentrated liquid that could not pass through the upstream set of filter plates through each downstream set of filter plates.
