Major Wastewater Treatment Cost Improvements at Food Plant
Mar 31, 2014
The subject company operates two production facilities close to each other, producing salads and a range of other specialty foods. There is a single centralized wastewater treatment plant at one site: the wastewater from the other site is brought in by a continuous trucking operation. Over the past few years production volume has grown, and it has become increasingly evident that the capacity and performance limitations of the wastewater treatment plant were creating a bottleneck, and also a barrier to any future expansion of the food production operation.
Historically, the amount of wastewater treated was close to 400 m³ per day, but this had been steadily increasing year on year. As a result of a planned expansion program over the next five years, wastewater volumes were now expected to increase to around 800 m³ per day, an increase of up to 100%. This was of concern to management on site, as the current configuration and performance of the plant had already for many years consistently failed to meet the standards in place for the level of Chemical Oxygen Demand (COD) allowed in the final effluent by the local authorities.
