The current unit
used was fitted with 4 cylindrical low pressure mercury lamps
which emit 100 W (W) power each placed in quartz sleeves. The
product was pumped through the reactor at a constant flow rate of
4000 l hr with Reynolds value (Re) of 7500.
The cleaning in place (CIP) was modified. Trisol 2000 was used
at 0.5% at 65 C for ±30 min, followed by rinsing with ±25 C water
for 10 min. P3-oxonia (2e10% peracetic acid and 20e60% hydrogen
peroxide)was added to the final rinse water at 1% at ±25 C for
±15 min.
