Ci y, six mo o s and h ee pumps a e employed, whe e he subme sible pump mo o unc ions o ex ac aw wa e om wells, he
eed pump ans e s wa e o he cla i ie ank, he dosing pump supplies chemical eagen s, he backwash pump and oo blowe
a e used o cleaning he il a ion ank, and he dis ibu ion pump deli e s ea ed wa e o consume s.
Field measu emen s show ha he main p o ec ion o he subme sible pump mo o is a 160 A MCCB, whe eas he calcula ed a ing
is 290 A. The main p o ec ion o he eed pump and backwash pump (1 and 2) in he ield uses a 100 A MCCB, while calcula ions
show 73.5 A and 72.5 A. The dosing pump mo o uses a 6 A MCB in he ield, wi h a calcula ed alue o 3.6 A. The oo blowe
mo o u ilizes a 20 A MCB in he ield, while i s calcula ed a ing is 30.75 A. The dis ibu ion pumps (1 and 2) use a 125 A MCCB,
whe eas he calcula ed p o ec ion a ing is 202.5 A.
Fo he conduc o sizing, a 4 × 35 mm² NYY cable is ins alled o he subme sible mo o , while i s calcula ed ampaci y is 145 A.
The dosing mo o uses a 3 × 2.5 mm² NYY cable wi h a calcula ed capaci y o 1.8 A. The eed pump and backwash pump use a 4
