Film processor

Abstract

The invention provides a film processor which comprises a shell and a rolled film assembly. Filler is arranged in the shell and used for reducing the space capable of containing raw water or concentrated water inside the film processor. Compared with the prior art, the space capable of containing raw water or concentrated water inside the film processor can be reduced to the maximum degree, so that the amount of the raw water or concentrated water needing to be replaced is reduced, and the purpose of reducing the consumed water yield to the maximum limit is achieved.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a membrane processor. Background technique [0002] When the current reverse osmosis membrane water purifier is shut down, the solute in the concentrated water on the raw water side of the reverse osmosis membrane will pass through the reverse osmosis membrane. The bigger the water purifier is, the longer the shutdown time will eventually be. When the water purifier is restarted, the initial TDS value of the effluent will increase significantly, or even exceed the standard. The water quality is obviously not as good as the effluent water quality in stable operation. The water purifiers in the prior art solve the above-mentioned problems by connecting a produced water return pipe to the reverse osmosis component water production pipe and connecting it with the inlet pipe of the high pressure pump. [0003] However, the existing water purifiers use the water return pipe...

AI Technical Summary

Problems solved by technology

[0003] However, the existing water purifiers use the water return pipe to introduce the produced water into the membrane processor, and replace the raw water or concentrated water in the membrane processor by the produced water to solve the above problems, which will cause another problem: it needs to consume a lot water production, resulting in waste of water production
