Background:
This bottling plants products ranges in sugar strength from 10% to 0.1% in their beverages. The cost to the plant for discharging high strength sugar solutions to the city sewer can be as high as $20,000.00 per-month. If the plant reduces the concentration of their waste below the discharge permit, then huge savings can result.
Problem:
To catch the sugar load as a result of product changes on each bottling line in plants with up to 5 individual lines. The waste sample that is to be analyzed is a mixture of the product to be bottled plus run off from the bottling/canning machinery. As a result the sample contains a significant amount of oil and grease.
Solution:
The LAR Elox 100 measures the strength of the waste in the sump when full. The analyzer starts a measurement cycle and a result is obtained in less than 30 seconds. The result is reported and the effluent in the sump is either pumped to the city sewer or to a holding tank, for high-level sugar solution. The high-level sugar waste is then taken away by truck or sent to an in-house treatment plant.
Conclusion:
By using the Elox 100 as an intelligent switch, the cost savings to the plant have the potential of reaching $20K x 12 = $240K per year. This application has the potential of being duplicated at all soft drink bottling plants that pay large surcharges for discharging high COD/BOD waste into the City sewer.
LAR has now installed over 15 Elox 100 units in this particular manufacturer's plants throughout the U.S.
