What are the chemical used in washing recyclable glass bottle in carbonated beverage industry?
An automatic bottle washing machine is usually used for this purpose. Washing occurs in a closed loop (CIP) through the following steps: • Primary rinsing using soft water at 25 0C, 10-60 sec. to remove dust. • Disinfecting using indirect-steam at 70 0C, 15-60 sec. • NaOH (3% concentration) rinsing at 80 0C, 15 min to remove label and contaminanats. • Direct cooling at 50 0C using soft water. • Final rinsing at 25 0C, 15-60 sec. with soft watre.
The soft water from cooling and final rinsing steps is recycled and used in the primary rinsing step. Large amounts of alkaline wastewater is generated from the unit and dumped at once at the end of the shift to the plant sewer system.
