WASHING METHOD OF POSITIVE PLATES
The washing method of positive plates is described as follows.
1. Firstly, pour water on the upper side of plates in the trolley and open drain to remove extra powder.
2. Stop the drain.
3. Fill the trolley with water.
4. When it is completely filled put air pressure hose and switches it on so that water gets into motion.
5. Continue the same for 15 min.
6. Shut off air and water valve.
7. Use Ph meter or Ph paper to check for acidic condition of trolley.
8. After washing, if Ph is correct i.e. at 4 then don’t drain the trolley and proceed to drying section.

NEGATIVE PLATES WASHING SYSTEM
The procedure used for negative plate washing is given below.
1. Trolley is filled with water & plates are placed in trolleys, and then bring trolley to washing area.
2. Firstly, pour water into the trolley through pipe.
3. When trolley filled open the drain such that plates don’t exposed to the atmosphere.
4. Set the rate of water flow accordingly so that plates don’t expose to atmosphere.
5. Continue the same for one hour.
6. Check Ph after every 15 minutes.
7. In the last 15 min check Ph after every 5 min.
8. When Ph standard achieve stop drain.
9. pH should be 4 – 5 on the completion of the process.
