|Wastewater treatment in the "Food and Beverage Industry" takes many forms. It
can range from simple pH control to biological systems reducing high BOD loads in
the thousands (mg/L) to 30 mg/L and even lower.
|Many plants install normal wastewater treatment technology that can cost $ MM's
more than should be spent ... and still give performance problems. Sadly, plants
and plant operators blame themselves for filamentous growth conditions and the
accompanying odor problems, or for difficulties in holding effluent to standards ...
when the problems are with the technology selected or the lack of proper
wastewater characteristics and biodegradability data.
|We will include examples of proper technology for food and beverage operations,
and both cost savings and cost avoidance detail, in this page as we develop it.
|When selecting the wastewater technology you must completely understand what is being
discharged and what your discharge permit calls for.
|Example of how critical this can be ...
|1. With most USA beverage plants the average BOD5 level can be 3,000 - 4,000 mg/L and even
higher. Periods of 10,000 - 15,000 mg/L BOD5 are not unusual. For most aerobic processes
this can spell major problems ... no matter how well designed, engineered or run. Aerobic
processes and filamentous problems were made for each other at very high loadings.
|2. With beverage plants outside of the USA, Japan and most of Europe, the returnable bottle is
common. This usually gives a beverage plant wastewater effluent in the 700 - 1,200 mg/L
range (BOD5). Just right for aerobic systems ... perhaps too weak a "consume" for anaerobic.
|3. Then you have plants that are partially sugar or HFS production and a heavy production in
bottled water or diet beverages. Current production and future plans/market needs must be
part of the technology selection process.
|4. Understanding the impact of the various waste streams can allow the savings of a large capital
expense in building the plant ... plus reducing operating expenses. With an existing WWT
plant major cost avoidance expenditures are often possible.
|5. For a number of reasons, it is most often not smart to build a wastewater system based on
future anticipated loadings. It is smart to leave room for expansion ... or introduction of new
