How to control the washing water of the washing plant equipment, water quality inspection and softening treatment of the washing room.
the washing medium of the washing equipment used in the hotel and hotel washing plant is water.
the whole washing process, such as fabric washing, pre washing, main washing, bleaching However, in order to ensure the quality of washing,

How to control the washing water of equipment in washing plant

therefore, maintaining a good level of water quality is one of the important methods for clean cleaning.
so how to control the washing water of washing plant equipment? The details are as follows:8 J- M* z; 1% U8 V -}: B7 Z1, water identification method, such as hard water and soft water identification method 8 T6@    r# Z$ g; IPrepare the materials for testing.
for example, water, test tube, soap solution, etc., first pour the water into the test tube, and put the prepared transparent soap solution into the test tube properly. In the process of adding, try to keep shaking while adding, and then check carefully. If the water solution is not turbid, the test tube should be filled with water, And the foam formed by sloshing on the surface of the solution remains stationary for five minutes and does not disappear. So this water is soft water, and vice versa, hard water.

If there is white sediment in the water, it can be concluded that the water is temporary hard water. If there is no sediment, take out the water sample and pour it into the test tube, Then add a little of the prepared transparent soap liquid, and keep shaking while adding,If the water sample becomes more cloudy and the foam caused by swaying is rapidly disappearing, it can be concluded that this water is permanent hard water.
