Sugar Processing Sugar
Concentration Duracon* RO-5
4040C-30D P1
The Duracon family of proprietary thin-film reverse
osmosis membrane elements are characterized by
high sodium chloride rejection. The A-Series membrane has an average rejection of 99.2% on 2000
ppm NaCl at 25°C and 225 psig.
The Duracon RO-5 4040C-30D P1 Elements provide
high flux rates at operating pressures up to 1,200
psi (8,274 kPa). This element is designed for daily CIP
and periodic hot-water sanitation, while still maintaining element integrity. They are typically used
for concentrating sugar in food-related processes
requiring stringent sanitary procedures. Applications include protein and sugar concentration, lactose recovery and waste water applications
requiring reduction of BOD.

Clean water flux (CWF) is the rate of water permeability through the membrane
after cleaning (CIP) at reproducible temperature and pressure. It is important to
monitor CWF after each cleaning cycle to determine if the system is being
cleaned effectively. CWF can vary ± 25%.

Hot Water Sanitization Recommendations: Elements should be cleaned with
approved CIP procedure and flushed with fouling-free clean water before sanitization process. Feed pressure during sanitization should not exceed 40 psi and
the crossflow should not cause higher than 2 psi pressure drop per element.
Heating rate to sanitizing temperature should not be higher than 5°C/min and
cool down rate should be the same.
