2 mill/30 y = 66666 Kr/year
66666 Kr/year / (5410,8 m3 + 3836,8 m3) = 7,21 Kr/m3 |
20 40 years
1,5 mill/30 y = 50000 Kr/year
50000 Kr/year / (871,74 m3 + 1342,88 m3) = 22,58 Kr/m3 |

Min. 4 years for the filters *
0,45 mill/20 y + 0,075 mill/4 y =
41250 Kr/year
41250 Kr/year / (10808 m3)
= 3,82 Kr/m3 |
* The Filtomat filter is estimated to last
2 years when it is used 24 hours a day and water is filtrated.
The estimated lifetime for the filters at VS is: (20*24*365*2) m3/y
/ (4769 + 6012) m3 = 32 y
The filters are not destroyed by filtration but by time and cleaning. A conservative
estimate lifetime guess is 4 years. |
