Advantages Of Membrane Filter Press System |
|
| |
 |
Reduced cycle time versus standard recessed chamber press. |
|
Cake discharges better than standard recessed chamber press. |
|
Produces drier cake than other forms of dewatering (centrifuges and belt presses). |
|
Produces better quality filtrate (captures more than 99.8% of all solids). |
|
Uses less chemicals for coagulating the sludge particles. |

Automatic Cake Discharge |
|
Four hydraulic closing cylinders, positioned at the corners, give even distribution of closing load over gasket sealing surfaces. |
|
Each filter press offers only static loading to foundations (no dynamic load) thereby making building design or steelwork simpler and cheaper. |
|
Because the closing load is balanced between the four hydraulic cylinders these presses can be used with maximum number of chambers (I.e. 200 chambers on 2000mm press). |
