Coca Cola Bottling Company
Originally Line 2 had two Crown Simplimatic water rinsers, each with 12 spray nozzles, running approximately 400 bottles per minute. The water usage rate delivered to the empty bottles was approximately 8 gallons per hour per rinser. Water rates charged by San Antonio Water Systems were approximately $.001/gal water and $.004/gal sewer. This water system contributed to significant empty bottle handling issues, which translated to filler downtime. Incoming water from the city aquifer is high in alkalinity, which resulted in rapid and massive lime scale buildup along the rinser discharge and air conveyor. The lime deposites on the equipment severely impeded production efficiency while intensifying sanitation costs and bottle scrap. Also, water residue leftover in the containers prior to the filling process contribtute to foaming at the point of fill, thus decreasing syrup yield.
Operations proposed to replace the two water rinsers with two waterless PET bottle rinsers (model AV-B1000). These rinsers required a minimal investment in parts and would realize significant cost savings. The City of San Antonio recognized the significance of this water savings project, and offered the San Antonio facility a water conservation rebate for significant water savings.
