The calculation of wet solid volume:

1. Filter area standard: according to Chinese National Standard GB, each 1m2 filter area equals to 15L solid volume.

2. Before filtering: Volume V1 (m3), according to experience, the slurry consistency a=97.5%~99.2%

3. After filtering: Voume V2 (m3), the cake moisture after filtration b=75%

4. Filtering cycle: the filter time or frequency t.

5. Solid volume balance method: V1*(1-b) =V2*(1-b), to get V2=V1*(1-a)/(1-b).

6. Filter area: =1000*V2/15/t=1000*V1*(1-a)/(1-b)/15/t

7. For example, there is a hardware factory whose wet slurry volume (to be discharged into the slurry tank) per day is V1=6.0m3, its slurry consistency is a=98.0%. Now they are planning to filter this slurry 1 time per day, the filter area needed will be =1000*6.0*(1-98%)/(1-75%)/15/1=32, according to the calculation we suggest to use a 40m2 filter press XMY40/870-U.
